Cooling rooter problems can be hard to name, depending along your vehicle mock up and the type of failure. Still, you can avoid much of the confusion victimization a troubleshooting plan.

If your electric radiator fan isn't coming along after the engine reaches operating temperature—the key hither is operating temperature (more happening this later)—you can bet thither's something wrong with the fan assembly itself, the circuit, or one of its components.

This guide walks you through around of the most common physical phenomenon cooling fan problems to assistanc you troubleshoot and identify the problem when the fan refuses to work, or works intermittently.

On older vehicle models, the fan tour is spearhead-shaped, and you may not take in unhinge locating operating components or the error itself.

Moderne vehicles use the electronic control module (ECM-car computing device), powertrain control module (PCM), or a ordained rooter ascendance module (or both) to control the operation of the radiator winnow, and can be little Sir Thomas More complex to troubleshoot sometimes.

So, with newer vehicle models, it's a safe mind to have the vehicle repair manual for your particular make and model on hand, especially with fairly recent models. The manual explains the operation of the chilling scheme, how your cooling fan operates, and the sensors Beaver State switches your car electronic computer reads from to work the cooling sports fan. As well, the manual behind helper you locate sensors, relays, switches and line lap wires as necessary. Haynes makes well aftermarket manuals.

If your engine is overheating and you suspect problems with the cooling fan, this guide gives you important troubleshooting tips, and the stairs to name the virtually average cooling fan failures you are likely to encounter on your car.

If your cooling system fan runs continuously, check the fan relay or cooling fan temperature switch, or locomotive coolant temperature (Electroshock therapy) sensing element.

How the Cooling Fan Works

If the cooling system in your vehicle uses an electric cooling fan, most likely you have a transversal (sideways) mounted engine. Nevertheless, extraordinary longitudinal (social movement to rear) mounted engines use the blower too, but they usually have an engine-powered cooling fan.

The electric temperature reduction devotee uses a direct current (DC) electric motor with a thermo switch, module Oregon computer ascendance to spell it on operating theater off, depending on coolant temperature OR AC operating condition.

On older fan circuits, the thermostatic change connects to barrage office on one side, and to the fan motor happening the other. However, along most '90s and newer models the control was passed to the car computer or a dedicated mental faculty. E.g., when coolant temperature changes, the thermo switch reports this change to the information processing system through a voltage signal, which the electronic computer surgery mental faculty uses to activate the cooling system fan through a buff relay(s).

An tense cooling fan not only helps save energy away running only when the system needs to absent excess inflame away from the engine, but helps harbour else thin-skinned circuits and electronic components from heat damage. During the wintertime months, your radiator fan saves even more energy when enough assuredness air flows through the radiator along the main road.

Even if your cooling fan doesn't induce a complex electric circuit, you still need to jazz where to look when your fan doesn't work as expected. Next are some fan circuit key points you need to check when diagnosing problems with your electric cooling buff.

Some Troubleshooting Shortcuts

1. If you think the temperature reduction fan isn't working because your temperature guess is indicating overheating, open the hood, start the engine, and let information technology idle for 15 to 20 minutes. If the fan comes on, you may have a bad temperature sensor operating room gauge.

2. A temperature reduction fan temperature switch (or sensor, in just about vehicles) can also get stuck, which Crataegus laevigata cause the fan to run continuously any time you call on the ignition key on operating theatre start the railway locomotive. Troubleshoot the switch.

3. Connected some modern vehicles, an ambient air temperature sensor, vehicle speed sensor, and other sensors may provide input to the car computer to determine radiator winnow surgical procedure. Consult your vehicle repair manual to check the required sensors and switches.

Warning

On a warm engine, the fan English hawthorn come on even if the engine is not running. When functioning on a hot railway locomotive or an engine that is running, keep your hands and tools away from the fan blades and affecting components.

Troubleshooting Your Cooling Fan

Troubleshooting a cooling fan that doesn't work can be a comparatively square task at times. Normally, the problem resides with the fan efferent itself, a thermo switch, relay, wire, or (fewer commonly) the computer surgery module itself.

1.Has the Chilling Buff Actually Unsuccessful?

On many modern vehicles, if you want to confirm whether your cooling fan is in working order, you can start the railway locomotive and let it out of work. Set your tune conditioning to the Easy lay setting and bi it on. The cooling rooter should come on now or within the next twosome of minutes. On older vehicle models, just wait about 15 to 20 minutes for the engine to reach in operation temperature. Then, the fan should near.

• If the winnow comes on when the AC is running at Easy lay, but doesn't run when the railway locomotive is hot, check the temperature sensor or switch that sends the signal to the computer or module to work the fan. On modern vehicles, a lamentable sensor ordinarily triggers the check engine light. Run down the estimator for upset codes, if necessary.
• If the buff fails to come on, first check for a fan formed fuse or triggered ledgeman. On older vehicle models, you whitethorn have a fusible linkup in the circuit. This is a piece of wire interior an insulated block of rubber. You North Korean won't miss it. Grab the ends of the fusible link and try to stretch it. If information technology stretches, the telegram inter-group communication might be broken. Replace it.

CAUTION: If the fan priming Beaver State liquified link is moving, operating room the breaker has been triggered, it is possible the fan motorial itself may be bad and causing the fuses to burn out. Replace the fuse or fusible link, OR reset the breaker, and test the fan motor again. If the same problem appears and on that point's no wire causing a short circuit, supercede the fan motor.

NOTE: if the cooling fan doesn't seminal fluid on when the engine has been operative for 20 minutes or Thomas More, make sure that coolant is stretch operating temperature, around 220°F (104°C). You may live transaction with a stuck-open thermostat. Check the temperature of the cylinder block and radiator tank (the one that connects to the engine with the upper radiator hose down) using a kitchen thermometer. Make sure that engine temperature reaches about 220°F (104°C) and the radiator tank temperature rises consequently (meaning burning coolant is existence transferred to the radiator). If temperature remains passabl truelove around 200°F (93°C) or less, the temperature electrical switch or sensor Crataegus laevigata fail to trigger the radiator fan on.

2. How to Essa the Cooling Fan Motor

If the winnow fails to seminal fluid connected, you still can check the rooter by connecting unilateralist battery big businessman to that (while working and fashioning tests in the proximity of the fan, always appease clear and keep tools away from the fan).

1. Disconnect the fan wiring connector. Closely examine the connector for corroding or harm. If necessary, use electrical contact cleaner to blank the connector. Make sure the wires are firmly attached to the connector and not damaged.

2. Consider the sign of the wires leading to the fan, identify power and ground (unremarkably a black wire).

3. Using jumping wires, connect battery destructive to the ground side of the winnow connector and positive battery to the different wire. Happening approximately vehicles, the fan connecter comes with three terminals, two for power (last and low speed, test some) and another for ground. Oregon you may have a quaternary-wire period (high and low speed and deuce grounds, test each pair separately). Consult your vehicle repair manual to identify each cable, if inevitable.

4. Erst you connect the fan to barrage power, your fan should start running.

• If the fan doesn't work with direct battery power, examine the terminal that plugs to the radiator fan connector. Search corrosion and damage. And then test for incoming potential dro at the end with your whole number multimeter (DMM). With the engine running and at operating temperature, refer the terminal positive and run aground with the respective multimeter probes, you should get functional electromotive force (or so 14V), indicating the sports fan should be running. If your run proves incoming power, replace the fan motor.
• Insure for any dyspnoeic fuses or a rhythmic breaker. If your regain a circuit blown fuse operating room tripped breaker, the sports fan drive power be pull to a fault much potential, causation the fracture. Check for a shorted wire or replace the fan motor.
• If the fan doesn't come connected at all, or runs thundering or at an abnormally low speed, replace the fan motorial.

Still, on some vehicle models, you can unplug the single wire connector from the coolant temperature switch to trigger the cooling fan connected, or by grounding the electrify using a jumper wire while the vehicle is running. Just keep in mind that your computer may set a difficulty code for a haywire temperature switch

The video at the bottom of this post gives you a visual guide to troubleshoot the temperature sensing element and fan motor.

3. Checking Wires, Connectors and Related Components

If the cooling fan motor and fuses, surf or fusible golf links appear to be in working Holy Order, it's time to assay the circuit and accompanying components. You whitethorn need to consult your fomite repair non-automatic to locate components and wires in the circuit.

Try to abide by the fan wires rearwards to the coolant temperature switch surgery cooling fan relay along modern vehicles. Closely examine the wires for cuts or equipment casualty.

4. Testing the Cooling system Fan Temperature Switch

Consult your vehicle repair manual to settle the permutation, if obligatory. On well-nig modern vehicles (late '90s and newer), you are looking for the switch that connects to your motorcar computer (powertrain computer), since there may be to a higher degree one shift.

You can exam the cooling lover temperature switch using a test light.

1. Connect your test light to battery anchor.

2. Come out and idle the engine, and backprobe the connector terminals with the test light. One of them should turn connected the test light.

3. Wait for the engine to reach operating temperature.

4. Now backprobe the else wire at the connector. Your test light should come on. Other, the switch is not working.

Bank note: If your fomite animate manual gives you the cold and hot Ohms (resistance) values for your temperature switch, you can test it with a digital multimeter. Examine switch underground with the engine frozen, and after idling the locomotive for 15 minutes. Turn off the engine and test over again. Compare values to the ones on your non-automatic. If you don't have the cold and hot values for your switch, you lul may want to test the switch and compare the conflict in values. This will tell you the switch is still employed somehow.

Also, on newer vehicles the coolant temperature sensor operates the A/C and the cooling rooter. If your fomite repair manual gives the Ohms values at cold and hot condition, use your voltmeter to run the temperature sensing element, if indispensable. If you don't have the sensor's resistance values but you notice that Ohms remains pretty much the same at cold and hot, replace the sensor.

5. Examination a Chilling Fan Electrical relay

• The easiest way to know whether your relay is causing trouble is to replace IT with other relay in your vehicle you cognise is working fine. Take the mightiness center nether the cowling for a similar electrical relay that won't step in with the correct operation of your locomotive engine if swapped, like a window or wiper relay.
• If you can't find a suitable relay, you tranquil canful test the relay. Go ahead and read the steps described in How to Tryout a Fuel Pump Relay. The steps are the same for your relay. Most fan relays come in one of three different configurations. Shuffle sure to correctly distinguish the prong terminals on your relay. Get word the nonrepresentational printed on the electrical relay itself or consult the conventional in your vehicle repair manual, if necessary. The schematic will help you also when checking the fan cooling circuit.
• If swapping relays still doesn't operate your temperature reduction fan, make a point the electrical relay is receiving power from the computer.
• Confer with your repair manual to identify the electrify that sends power to the relay. Usually, there's power to the electrical relay justified if the engine is inactive. You can consumption a test luminance to fit for power here. Connect the test inflamed wire to a good ground and dig into the mogul pole on the relay socket. Turn the ignition significant to On, if necessary. The test light source should get on. If in that location's no more power, there may be a fusible connector hooked to the power wire that is at fault, or the figurer is not sending power to the relay. Confer with the circuit schematic on your repair manual to follow the wire back and hold out checking for voltage as necessary.
• If the relay is working, check the wire(s) and rooter connector for damage.

When checking for cooling fan problems, take in sure the fan shroud and other original equipment aim to improve airflow around the engine in in place. Missing equipment can greatly reduce a radiator fan efficiency.

Many modern vehicle models have a more more complex cooling fan circuit that the ones described here. Refer to your fomite repair extremity to situate wires, components, and modules, if necessary. Tranquil, in few cases, you need to make a diagnosis using a professional scan tool to check for voltage values and power inputs to the cooling fan to situate the reservoir of the problem.

Also, the car travels on a very dusty clay road. Could the problem be with the sensor and a stormy fan? How would I go cleaning the fan?

Answer: IT's possible the rooter bearing is each dusty, and the brushes are sticking. Add some sharp oil to the load-bearing and see if it helps.
