If its a V-8 like mine the electric fan is not the main fan to cool the engine. The viscous fan is. Its the one that runs of the engine belt. Just replaced mine. The viscous part goes bad and the fan will not run at the proper speed, it may spin but not at the full speed it should. It should make a roaring noise when hot and when you first start it up in from being cold. If not it may be bad. Turning AC of may help tell its fixed.

To replace the fan relay, it is located behind the bumper of the right headlight (if you are standing looking at your Jeep from the front, it's the one on the left.) It's screwed into the frame and connected by a cable. You can take off the bumper or do it the easy way like I did. Remove the right headlight by loosing the bolt on top (it's a long bolt.) Pop out the headlight assembly then you can take a hole-saw and cut out some 1" to 2" openings. You'll see the relay underneath. It's about a 50.00 part and takes less than 20 minutes to swap out using the method above.

Radiator fan wont work


There is a temperature sensor in the engine block. This controls the fan. Sometmes it can be part of the thermostat but most usually it is a small switch that looks like a bolt with only one lead coming from it. It is possible to buy these temp sensors to retro fit into the cooling pipes. They can then be connected to the fan relay. They usually switch an earth for the relay coil, this will allow the power to the fan. They usually switch at 80 to 90 deg C.- This is the optimum temperature for an internal combustion engine.

My 1993 Eurovan is overheating and I noticed the fan does not come on. My mechanic replaced the fan switch but it still does the same thing. My mechanic doesn't think it is the fan itself because he says...


Yes, the fan switch only operates the relay.
Look for the following image:
http://www.traderscity.com/board/userpix22/20550-radiator-fan-control-module-relay-vw-eurovan-701-919-506-1.jpg
I have to ask if the switch is the right one or installed correctly?
If there are 2 fans, I would assume there would either be 2 switches, or at least 2 wires to the switch (3 would also be possible).
The thing to do is test the switch by bypassing it with a shunt to ground.
In fact, it is also possible the switch ground is what is bad.
The fan should come on when switch is shunted, I believe even with ignition off.
So be careful.

My 1996 toyota avalon is overheating. There are no leaks, thermostat is new, radiator is new and has been flushed, changed the fan relay. Don't know why its overheating.


Is the fan coming on? If not, possible lower radiator fan switch/sensor? No leaks... So overflow tanks level stays stable? How do you know it is overheating? Elevated temp guage? Engine smells overheated? Both? We need more info.

The car is overheating and when you first start the car the fan runs for maybe 15 seconds and then quits. What should i be looking to replace? Is there a method I can use to check to see if the fan is...


It is common for the fan to run momentarily when motor is started. After that the fan should only come on when the engine reaches a certain temperature. If the fans are not running when the engine is overheating, then it is usually the fan relay switch. Your local auto parts store should help you to locate the relay switch, and they are only a few dollars to replace. And can easily be done in 5 minutes or less.
To test the relay first, with the key in the on position, use an electrical tester to find the "hot" wire going to the relay and using a small piece of wire, connect that "hot" wire to one of the other connectors on the relay. If the fan comes on when you do this, you know that the relay switch is indeed defective.

Fans not working (overheating)


if you are losing coolant is it a bad radiator or just overheating or is it escaping into the engine pull the dipstick and look for water in the oil you will see water bubbles in it however the relay could have a short in the wiring at some point check with a test light for power rusty connections well ?

Overheating 93 sl1


The cooling fan circuit is composed of basically 3 components. The fan, fan relay, and a cooling fan switch. If you are sure the relay and fan are ok, it is probably the switch. It is located on the top of the engine block very near the upper radiator hose connector, close to the thermostat housing. A car parts store can tell you where it is located. NOTE: There is more than 1. If you have a temp. guage, there is a sender that operates the guage. Also, there is 1 that sends information to the computer. So, make sure you ask for the cooling fan switch when you talk to the parts store people.

1999 discovery is overheating, cooling fans are not coming


This is because of the improper circulation of the coolant, if the AC turned on then the engine load will be considerably increase and spoil the thermal switch (which initiate the cooling fan to run). So you better clean the radiator and check the radiator pump, then replace the thermal switch to get the things done.
