OEM for fan 

Radiators, as the name suggests, are devices that radiate heat. In older cars, the fan used to operate with the assist of an engine. In Germany, the Günter brothers created an option design and style combining evaporative cooling and surface radiators spread all over the aircraft wings, fuselage and even the rudder. The most obvious, and typical, resolution to this dilemma was to run the whole cooling system below pressure. Therefore, timely detection and correct disposal of overheating can efficiently decrease losses. This transmission cooler is like a radiator within a radiator, except, of course, when as an alternative of exchanging heat with the air, the oil exchanges heat with the coolant in the radiator. Or, you could get rid of the fan and clutch altogether and set up an aftermarket electric fan kit to cool the radiator. The bypass system is a passage that makes it possible for the coolant to move by way of the engine and then to bypass the radiator to balance the temperature. We can clearly see that the 27mm Denso core flows much more airflow for a offered static pressure. This causes the fan to spin faster for improved cooling. With a shorter heating time and greater heat capacity, you can use your energy far more efficiently and significantly decrease your heating fees. Bear in mind, with out the radiator fan the only way to draw cool air via your vehicle’s grille and into the engine is by motion. These scenarios can quickly grow into bigger issues for your cooling system and your engine. When the valve is shut, fluid flows back towards the reservoir but doesn’t return, triggering the clutch to slip and also the fan to turn more gradually. Parts and accessories for your Volvo like your Volvo radiator are created accessible by Volvo Components and Auto Parts Volvo radiators would actually give your Volvo far better and enhanced performance. The radiator is a large matrix of small pipes, and when the coolant passes via the cooling cores of the radiator, it cools down, eliminating the heat it has accumulated from the engine. If you do not repair the leaking, you will sooner or later smell burnt coolant from beneath the vehicle’s hood. To shield your engine, get a replacement fan as quickly as possible by ordering from right here at You can discover a variety of components for your automobile here, for what ever you drive. Employing flash evaporation, it sprays out fine water particles that evaporate speedily into the air and lowers the apparent temperature to up 25-30 degrees Fahrenheit. Your auxiliary fan assembly can be located straight in front of the radiator and directs colder outdoor air across the radiator fins. As steam is significantly much less dense than water, a correspondingly larger surface location is required to provide sufficient airflow to cool the steam back down. Following I’d completed rebuilding the engine last spring, I reinstalled the original radiator and electric fan, as there didn’t appear to be something naturally incorrect with either of them (the radiator appeared totally free of apparent corrosion when I peered inside, and the cooling fan, even though it looked like it originally powered Churchill across the English Channel, spun smoothly when tested). In most circumstances, an electric fan forces the cool air from outdoors into the radiator, thus speeding up the cooling approach. Oil filled radiators are normally the initial selection, although you can also acquire the variety that has a heating element in the bottom of the heater and a grill exactly where the warm air is expelled towards the prime of the heater. Collectively with the radiator , a vehicle fan contributes to the cooling of the engine of a vehicle. As soon as the fins are heated, they release heat into the air, cooling the engine. The AC Delco Auxiliary Fan Assembly increases cooling of your car’s coolant. Verify for leakage frequently: The coolant might leak at the hoses or the cap which would leave the radiator inoperable right away. If there is voltage operating to the cooling fan, you possibly have a undesirable fan. For the test rig, I’ve built an exhaust collection chamber that’s fundamentally a extended piece of 8″ PVC with insulation, a bunch of flow spreader tubes, and an MCR120 radiator mounted to the face of it. The anemometer hot wire sensor is then mounted to the back of this to measure air speed by way of a smaller port. Sometimes, a clogged radiator can be “rodded out.” If the radiator then passes a new flow test, it can be reinstalled for further use. The flow of the liquid coolant determines the actual cooling capacity of the radiator. The radiator is filled with a liquid coolant, typically a mixture of water and ethylene glycol.

An aircraft radiator contained in a duct heats the air passing via, causing the air to expand and gain velocity. Engine-driven fans are usually regulated by a fan clutch from the drivebelt, which slips and reduces the fan speed at low temperatures. The cooling fan does not have a clearly defined service life. This makes use of a single surface blended into the fuselage or wing skin, with the coolant flowing by way of pipes at the back of this surface. Several aircraft were built utilizing their design and set quite a few performance records, notably the Heinkel He 119 and Heinkel He one hundred Nevertheless, these systems essential several pumps to return the liquid from the spread-out radiators and proved to be really tough to hold operating properly, and had been considerably much more susceptible to battle harm. One particular of the benefits of electric fans is they come in all types of distinct sizes from slimmer profiles to those with different widths and heights. As the coolant spreads more than the prime of the radiator tubes, it transfers heat to the air. Unbolt the fan shroud from the cross member and slide it back more than the mechanical fan but do not remove it. Use care not to loose the clips that the fan shroud and electric fan bolt to. If they break or get lost, you can get replacements at most hardware stores. If you are adding an electric fan as an auxiliary cooling source you can use a pusher style. Yet another consideration for folks who may possibly be concerned with excessive fan noise is the blade shape, this is exactly where s-blade electric fans come in compared with straight bladed fans. In a vehicle, motor oil is pumped all through the engine block to lubricate the components, but this is insufficient to overcome the tremendous heat generated. General and to summarize the cooling technique of your car – be it vehicle, truck, or SUV does exactly what its name suggests – it removes, reduces and fundamentally its function is to take away heat from your engine method expelling this waste heat into the nearby air. Thermal kind cooling fan clutch There are two easy kinds of fan clutches: thermal and non-thermal (also termed torque limiting”). Engines need to have heat to operate effectively, but demand effective cooling—especially in functionality applications—to remove as much energy-robbing heat as achievable. This is called the Meredith effect , and higher-overall performance piston aircraft with nicely-designed low-drag radiators (notably the P-51 Mustang ) derive thrust from it. The thrust was significant sufficient to offset the drag of the duct the radiator was enclosed in and allowed the aircraft to attain zero cooling drag. Auxiliary fan assemblies enhance the circulation of cold air by means of the car’s coolant program, specifically when the auto is idle. There are two varieties of fans, electric and mechanical. They occasionally run following the engine has been shut off to bring the temperature back to regular specifications. In addition, most fan clutches are thermal, so they engage and disengage according to air temperature to make positive the vehicle will not get overcooled. Interestingly, storage heaters had been initially created for the duration of the strikes of the late seventies and there is an argument that the government encouraged their use at this time as they were keen to hold the power stations running to make the country dependent on the coal business. The fins conduct heat from the tubes and then transfer it to the air flowing via the radiator. Driven by a pulley (like the manual fan), the insides of the clutch has fluid that produces internal friction that couples with a bi-metallic sensor equivalent to a thermostat. This indicates that fan heaters will blast warm air into a area quite quickly, but as quickly as they are turned off, the room will cool practically immediately. If there is a dilemma with it, you will not be in a position to turn the fan blade very easily when the auto is off and the engine is cold. The following three forms of electric heating consume electricity “on demand” unlike storage heaters. When things go from negative to worse, and your broken radiator fan causes a disastrous overheating episode, you might have no other choice but to get a replacement for your radiator unit. The cooling fan relay is generally beneath the hood. It need to cool the antifreeze that circulates through the block and head passages and reduces the engine temperature. If the fan is not operating even when the vehicle is heating up there may well be a difficulty with the wiring.

In case you notice the engine generates heat more quickly, there need to be some thing incorrect with the cooling mechanism and it requirements maintenance. The engine of a vehicle has a combustion chamber exactly where continuous explosions take location and as such the engine heats up quite rapidly. A radiator is responsible for handling further energy or heat that the engine produces to perform well. Cooling fans are categorized by cubic feet per minute (cfm) ratings. A corroded or broken radiator can swiftly grow into bigger troubles for your cooling system and your engine. The excessive heat of the engine compartment and harsh components of the road also contribute to premature failure of radiator fan elements. The radiator caps are a vital element of the cooling technique and are prone to fatigue and wear, and this might lead to loss of stress handle. Contemplate two cooling systems that are otherwise equivalent, operating at an ambient air temperature of 20°C. These fins heat the air that moves more than them and cool the oil as they cool. Initial check the fuse to the cooling fan, if undesirable, replace it. When the car is acquiring hotter than regular and the fan should be on, unplug the fan wire. Price of the fans aside, push + pull on radiators has usually worked fairly well and a great way to get a bump in functionality without having rising noise too considerably a lot more. Some of the much better electric fans can push over 3,000 cubic feet of air per minute and have ten blades. Following you have repaired the leaks, it is advisable to refill the cooling program with a high high quality coolant. This component controls airflow and minimizes the effort your fan has to make in order to support your cooling program. The radiator’s job is to maintain the coolant cool so that when it returns back into the engine, it is able to absorb far more heat. Most of the fuel power in a automobile is converted into heat (around 70%), and it is the job of a car’s cooling method to take care of that heat. An electric element is concealed within the radiator, which heats up and radiates heat out evenly from the front of the radiator. The auxiliary fan assembly improves air circulation by way of the radiator so that the coolant is successfully cooled. Their principal advantage is that they are less complicated to repair than the recently manufactured radiators. Aside from the radiator, the cooling program is composed water pump, freeze plugs, head gasket, thermostat, hoses, heater core, fan clutch and radiator fan. As you would know, all internal combustion engines produce power by burning fuel and this energy drives the wheels of your car. The purpose of the radiator in your Nissan Altima is to maintain the engine from overheating. The cooling technique comprises of: the radiator, radiator fan, water pump, thermostat, stress cap, bypass method, hoses and heater core. If the thermostat is broken, it can’t signal the radiator to cool the engine down at the appropriate time, hence causing the engine to overheat. These may be either oil-air radiators, as for a smaller version of the main radiator. Radiator Cooling Fans transfer heat blown through it by the fan. Many tubes are arranged parallel and the superheated liquid flows from the inlet even though the fins conduct the heat from the tube and transfer it to the air, blown by the fan by means of the radiator. Usually, there are two kinds of cooling systems employed in a car: liquid cooling and air cooling. An evaporative cooling program may well operate among 80°C and 110°C, which at very first glance seems to be much significantly less temperature distinction, but this evaluation overlooks the enormous amount of heat power soaked up throughout the generation of steam, equivalent to 500°C. The flex fan has gained recognition in the higher-efficiency car and racing circuit. Everyone who has utilized an electric heater knows that they dry out the air. The most affordable explanation was that the fan that came mounted on the radiator merely was inadequate to the job of pushing sufficient air through it. Make the most out of all the heat generated by your radiator with this Normal Radiator Fan from Radfan, which will not only leave you feeling cosier but also save you income in the long run. The Valeo auxiliary cooling fan is an electric fan that pushes outside air over the radiator to hold it cool. Keep your heating bills in verify by producing the most of the warmth your radiators pump out. My replacement heat sink is a Nactua NH-D9DX i4 3U (not an affiliate link), chosen because it’s got great cooling capacity and it doesn’t overhang the ILM (that is, it goes straight up, and the memory that is next to the ILM will not result in a clearance problem).

Hence, typically, liquid cooling systems shed capacity as the aircraft climbs. Later, fans were added to the kit to improve the cooling impact. A fan belt operates the engine’s cooling fan. The car’s cooling technique is one of the car’s most critical elements and keeping it in perfect situation is the important behind a reputable automobile. Heat from the coolant in the radiator core tubes is transferred to the fins and to the air flowing via the radiator, thereby lowering the coolant temperature. Allowing as well much flow of coolant to the radiator would outcome in the engine getting over cooled and operating at reduced than optimum temperature, resulting in decreased fuel efficiency and increased exhaust emissions. For small radiators or electric radiators, there are various attachments that enable this to function with practically any option. The liquid coolant, generally a mixture of water and ethylene glycol, is added by way of this cap. Hot right after absorbing all the heat in the engine block, the coolant enters the radiator through the radiator’s upper hose. They take far more punishment from the heating and cooling each time the motor is started than wiring ever does. This averaging involves the average of the fan rpms at the time of the test as nicely as all the temperatures. The Coolgate HD has very excellent all around efficiency being one of the couple of slim radiators to be tuned in the middle with far better than average overall performance at really slow speeds. The radiator fans operate quickly to offer enough airflow to your engine and to maintain it cool. If your radiator has overheated one too numerous times, it is possibly best to appear for replacement radiators in North Hollywood. Step 1: Find the radiator drain plug – normally close to the lowest point of the radiator – and open it to drain any coolant into a catch basin. Some fans are portion of the crankshaft or water pump, which implies they turn all the time. Unfortunately, the design and style of these aluminum radiators are such that they either have no fan brackets on them, or brackets are produced particularly for the fans they’re sold with and usually no drawings are obtainable online to see if the holes line up with a Spal fan. For maximum cooling place your fan on the highest attainable setting. No matter how gutsy its engine is, it cannot perform generally without a cooling method. A lot of high-overall performance aircraft nonetheless suffer intense overheating problems when idling on the ground – a mere 7 minutes for a Spitfire five This is related to Formula 1 cars of nowadays, when stopped on the grid with engines running they demand ducted air forced into their radiator pods to stop overheating. The radiator is the major component of a vehicle’s cooling method. PWM controlled fan with an distinctive 9 blade style is engineered to create greater airflow whilst keeping quiet. The Pure Duo fans guarantee a lot more efficient cooling overall performance under intense operation. A car’s engine has several components moving constantly to create energy. When the auto cools down, you can pop the hood and open the radiator cap. The Volvo radiator is a sort of heat exchanger developed to transfer heat from the hot coolant that flows through it to the air blown through it by the fan. As opposed to the primary fan, the auxiliary cooling fan is driven by electrical energy. Speedcomfort is a radiator fan that promotes convection of warm air from your radiator around your home. Subsequent the fans are elevated to 2200RPM and heat elevated to 300W and information logged and extracted once again. When installing a radiator, your mechanic ought to often use silicon tape (plumbers tape) when they connect to the oil fittings and they must also tighten any nuts exactly where the radiators connects to hoses that carry coolant. Coolant should be replaced in your radiator on a routine basis in order to sustain a appropriately-functioning radiator and engine. When the height of the completely opened valve is not significantly less than 9 mm, the thermostat can be place into the water for heating inspection. They have effective air movement and high-powered motors to produce greater speed in order to cool a humid air. I took a trip to MicroCenter (probably my new favourite shop) and checked out their selection of 120mm fans. The water pump circulates the coolant by means of the engine. The auxiliary fan assembly maximizes air circulation by means of the radiator so that the cooling method is appropriately cooled. If you can’t see something, hold in thoughts that your radiator fan functions hardest when your engine is idling.

The engine could be able to remain cool at low speeds simply because it’s not working as challenging and not creating as considerably heat. From time to time you may possibly want to function on the radiator or on other components of the car’s cooling system and you have to be really cautious when undertaking so. The radiator’s fan is quite powerful and dangerous and you ought to disconnect its wires that come from the battery (the fan is typically electric driven and commanded). Placed behind the radiator – even though protected from the dirt and grime, and to a particular extent the rainwater hitting the front of the auto – the conditions are considerably hotter, to the possible detriment of the fan’s electric motor. Even so, as spring turned to summer time, I discovered that the car’s temperature gauge would drift into the red if I got caught in hot traffic, and if unchecked, the car would puke coolant out from below the radiator cap. Engine radiator fans transfer the excess quantity of heat that is made by the car and as a result protects the parts from becoming burnt and wearing out prior to time. Thermostat is an important element of a vehicle’s cooling technique. When you enhance your car engine power, a lot more heat is made. Fan manufacturers base their measurements on a standard measurement with clean, dry air at a density of .075 pounds mass per cubic foot, barometric stress at sea level of 29.92 inches of mercury, and a temperature of 70°F. 1. Single high overall performance fans need a minimum of three.five” clearance in between your vehicle radiator and engine pump. 120mm fan with special 9 blades design is engineered to produce higher airflow without compromising on ultra-silent operation. Coolant is heated in the engine, becomes much less dense, and so rises. Some engines have an oil cooler, a separate tiny radiator to cool the engine oil Cars with an automatic transmission typically have additional connections to the radiator, permitting the transmission fluid to transfer its heat to the coolant in the radiator. We have universal fans suitable for a variety of applications, fan kits, and fans for popular automobiles discovered on Australia’s roads. Boilers also operate a lot more effectively the cooler the return temperature, so by extracting as much heat as achievable from your radiator will aid them with this. A broke fan belt could be an additional explanation for the engine overheating. For lengthy vehicles, such as buses, side airflow is most typical for engine and transmission cooling and leading airflow most typical for air conditioner cooling. If it really is not, there may be two factors – a undesirable electric fan or undesirable radiator fan switch. In common, I like these fans, they are undoubtedly good for massive old residences that struggle to heat up a room. To test this, let your vehicle idle lengthy enough for the engine to heat up. Hold an eye on the temperature gauge. Radiator fan assemblies include structural, mechanical and electrical parts, so they’re a lot more expensive than most fans in your car. Whichever type of electric heating you opt for, we constantly suggest seeking at the numerous power providers’ tariffs to compare pricing as the price of electrical energy can vary drastically pricing does not only vary in between suppliers but also amongst the wide varieties of tariffs provided by every single supplier. It draws cooled water or coolant from radiator by way of thermostat. In automobiles and motorcycles with a liquid-cooled internal combustion engine , a radiator is connected to channels operating via the engine and cylinder head , by means of which a liquid (coolant) is pumped This liquid could be water (in climates exactly where water is unlikely to freeze), but is more frequently a mixture of water and antifreeze in proportions proper to the climate. The parts you require, like a Behr auxiliary fan assembly, are just a mouse click away when you get them from Folks who want the most from their automobiles understand that only the highest high quality aftermarket and OEM parts ought to be used for repairs and maintenance. So ask your self this question: Is it worth it to drive a automobile with no a radiator fan. Natrad’s range of electric fans offers an economical cooling answer for car radiators and condensers. Auxiliary fan assemblies facilitate the movement of cooler air into the engine’s coolant system, specially when the car is idle. I have a loop with three noctua nf p12 pushing fans and i have scythe karma low noise fans but low rpm too (500 rpm) that i don’t use becasue they are not adequate powerfull by themselves.

When the car has approached larger speeds exactly where the air has a “ramming” effect on the radiator, the fan shuts off due to the fact it does not have to be employed. As a result, verify the radiator stress cap for the advisable system stress level at normal intervals. Radiators are also often utilised to cool automatic transmission fluids , air conditioner refrigerant , intake air , and occasionally to cool motor oil or power steering fluid Radiators are normally mounted in a position exactly where they receive airflow from the forward movement of the automobile, such as behind a front grill. One of the issues right here may be with a vehicle stuck in the mud with a high-revving engine, which would trigger a no-fan situation, as a result more than-heating the engine given that the vehicle cannot move through the airstream. Your vehicle’s auxiliary fan assembly can be located straight in front of your vehicle’s radiator and directs cooler external air over the radiator fins. Your engine could overheat if this fan goes out, especially in quite hot climate. From there, the coolant trickles down or across the modest tubes that tends to make up the radiator core. Extreme harm can result, such as blown headgaskets, and warped or cracked cylinder heads or cylinder blocks Often there will be no warning, since the temperature sensor that supplies data for the temperature gauge (either mechanical or electrical) is exposed to water vapor, not the liquid coolant, providing a harmfully false reading. Fan: The fan is an crucial component of the cooling technique. Some radiator cooling fans are specially created to work on the basis of a thermostatic witch. A radiator fan, commonly identified as a radiator booster, utilizes a comparable principle but rather than reflect the heat back it uses a little electric fan to blow the warm air back into the space. Automobiles operate on a wide range of temperatures, from beneath the freezing point to more than 38 degrees Celsius (one hundred F). Water is an powerful absorbent of heat but it freezes at too high a temperature for it to be work nicely in auto engines. A fan to draw cool air via the radiator. Auxiliary fan assemblies improve the movement of cool air by means of the engine’s cooling method, specifically when the vehicle is not in motion. These kinds of thermostats do not perform nicely at cooling program pressures above about 7 psi. In common, a fan’s CFM is proportional to the amperage that it draws, so although it’s effortless to say that you want the largest, hardest-blowing fan you can get, there are electrical consequences to it—you need to have to be specific that the alternator can handle it, and it is probably that you will need to install a relay and thick cabling from it to the fan so the further current isn’t running by way of the car’s current thin wiring. Yes, fans can also be utilised to warm the air. The part of the radiator fan in a vehicle’s cooling method is to cool the engine system and to draw air into the radiator to stop the engine from overheating. Compared to the common case fan, the mixture of 3 Riing 12 radiator fans and RL360 radiator delivers 40% better cooling efficiency. Axial flow pumps – for in impact that is all this kind of cooling fans are – are great for moving big quantities of air at low pressure differentials, and any intake stress loss as a outcome of the restriction of the radiator matrix will have some effect on fan efficiency. This increases the turbulence of the fluid and in the process, rising the cooling capacity of the radiator. A mechanic would initially check all the other things associated to the radiator fan to make a appropriate evaluation. All factors getting equal, and maintaining the radiator in the very same position in relation to the engine, it will also reduce the blockage impact, assuming the engine is mounted behind it, as in most front-engine automobile layouts. The radiator is helped by a fan that blows coolers outdoors air to speed up the cooling procedure. It is the radiator’s job to remove the heat from the engine and it must function at maximum efficiency even in extreme circumstances. To avert the water inside radiators from freezing, a excellent quantity of antifreeze needs to be combined with the liquid. Fan guards drastically impact air flow to electronics to aid them maintain cool, and for that reason can aid your electronic devices final a wonderful deal longer. A Behr Auxiliary Fan Assembly augments the radiator in lowering harmful heat levels of antifreeze.

Care ought to be taken to make certain that the flow of the coolant is not hampered by any obstruction. Replace yours as quickly as achievable and steer clear of overheating or damaging your engine. Interestingly on the other hand, automotive cooling systems are not almost as important to the running and ongoing upkeep of diesel engines. Below we have offered a summary of the electric heating options obtainable on the industry detailing their pros and cons to support you select which alternative is the ideal for your residence. If the fan fails to come on, it can lead to the engine to overheat. Then the fluid is circulated by the water pump unit, via the channels of your engines’ heavy metal block, by means of the rubber coolant hoses, which you must be effortlessly spotted when peering into your engine compartment. On direct air-cooled engines this is not a concern for the bellows thermostat that controls a flap valve in the air passages. The radiator-cooling fan is specially designed in such a way that it turns on when the temperature of the engine rises and stops when the temperature is standard. The writer explains that in order for car radiators in North Hollywood to get in as a lot coolant as automobile engines need, the hoses conveying the fluid ought to be huge enough tightening the nozzles or joints also helps increase efficiency by preventing leaks. They all have the exact same simple function, which amounts to drawing in further air, but particularly at low rpm situations and instances when the car sits at an idle. Logically, nevertheless, the cooling fan keeps the cooling method at the optimal temperature to stop the hotter than standard engine temperatures, as described above. An early technique was to take advantage of an aircraft’s abundant airflow to replace the honeycomb core (a lot of surfaces, with a higher ratio of surface to volume) by a surface mounted radiator. You need to make it your every day habit to check the coolant levels in your radiator. These coolant hoses pass from their fitting on the engine ultimately to the radiator. A lot more basically they may be oil-water coolers, where an oil pipe is inserted inside the water radiator. This will reduce the powerful back-stress against the flow of air, and at the limit of its overall performance will minimise the opportunity of the air stalling via the compressor blades. If the radiator does not have cool air blowing on it continuously, it will overheat ultimately, so you’d need to have the perfect combination of weather and targeted traffic to drive effectively without a radiator fan. SpeedComfort, a radiator fan, claims to boost the radiator heating power by 20% minimizing the warm-up time by 50% and reducing bills by 22%. Possessing a green cord for your cabinet cooling fan can help make positive that you only use your fan when it is required, as a result employing less power and creating some important savings. A TYC Auxiliary Fan Assembly aids a radiator in lowering the excessive heat of the antifreeze. Most electric fans come equipped with thermal-sensors that activate the fan when it reaches a hot temperature. Additionally, you will uncover the anti-freezing coolant dripping in to a tiny puddle beneath your vehicle. The truth that radiator pipes are narrow implies it requires significantly less time for the antifreeze to cool down. This was a major limit on efficiency throughout the 1930s when the introduction of turbosuperchargers first permitted handy travel at altitudes above 15,000 ft, and cooling design and style became a main area of research. Design of Fan blades and Motor Help ribs in RFM is critical to improve Flow noise, i.e. Air cutting noise. You also want to check and identify any external leaks and damages to any of the components of the cooling technique that incorporate the water pump, radiator, engine coolant passages, heater hoses and heater core. If we’re talking what do you do with a restricted space, there is also often the option to run fans on both sides of the radiator in series. The fan clutch is responsible for holding the fan to the engine and turning it. If this assembly burns, you would have to replace it with a new a single. Inside the cooling program, the coolant is sealed and it is below pressure and that is why, in these conditions, the coolant will boil at about 120 degrees Celsius. Install the new radiator, with fan assembly, into the vehicle. The radiator fan does not function permanently but only when the temperature switch, connected to the radiator indicates a rise in temperature above a particular set level.
