Based on your question, I am assuming that the coolant fans are running? They should be, well they should if the temp gets to the a certain level. Not all cars have only one but some have two fans set up on different temp on/off. If you wish to check them to ensure they are running, you can check the electrical current from the temp sensor to the fan switch to ensure there is current going to the fans, obviously if not...that would be the problem. check out this video with all of these how to do yourself described....

Make sure the radiator pressure cap is the correct one and that the hose is not soft--check the lower hose and heater hoses for softness as well. They should be firm, but not hard or cracking. The temperature sensor is reporting normal operating temperature, so it and the thermostat are working correctly (hot water would blow out of the radiator if it were stuck). Check the cooling fan for free turning and no noise. Check it's grounding connection. Check the fuse box for blown fuses to the fan and to the A/C compressor. Make sure all the relays and fuses are firmly pressed into their sockets. Check the A/C compressor clutch winding for resistance--should not read infinity. Does the blower motor for the heater/A/C run when either is turned on? The A/C switch on the dash may be defective.

SOURCE: 1992 Ford Taurus with a 3.8l V6 the cooling fan

The Taurus has Two temp sensors. One for the dash, which is isolated, then one for the PCM, it also controls when the fan relay should actuate. Its a 2 wire sensor, just above the thermostat. If you remove the harness from that sensor, and the cooling fan comes on, at any temp, (should take 5- 10 seconds) then thats your fault.

Engine coolant fan wont come on. The fan motor is fine. whats next?


You still have many other components in that system that has to be in working order for the cooling fan to work properly. The cooling fan is turned on when engine temp reaches a predetermined temp, usually around 220-230 degrees F. the ECT (engine coolant temp) sensor siganls the ECM (Engine Control Module) to ground the cooling fan relay or cooling fan module(if equipped) and if the cooling fan fuse is good and the fan has power to it the realy will complete the ground for the fan to run. You may need to have a qualified technician diagnose the problem if the obvious things like fuses and good grounds are not the problem.

Hope this helps.

My fan never stop running.


Stuck cooling fan relay, A/C is on, bad coolant temp sensor. relay is in the fuse and relay panel, look in your owners manual for location. When you run the A/C, the cooling fan runs.

Engine cooling fan stopped running. I checked fuses all good.


Should have a relay for the fan, but typically the coolant temp switch will go bad, not the temp sensor but the switch which is usually located around radiator. Most parts stores carry them & should be able to assist you with the proper location as well.

1993 pontiac bonneville electric cooling fans relay location


Hi, check.........I need to know which fuse runs the cooling... on this forum thread. Its not a fuse if the fan turns but could be fan relay. Unplug the coolant temp sensor lovated just below the thermostat houing and see if the fans come on. If they do, it might be the coolant sensor that is bad.

Cooling fan switch/or sensor


The Coolant temp Sensor is located right under the top radiator hose (on the engine side), with a little black connector!, You might have to remove th etop hose to get to it with a deep socket and extension!.
Also Dont Forget to blled the coolant system by the bleeder valve uptop right near/above the coolant sensor!.(10MM Mini socket w/ extension IIRC!)

95 grand am radiator fan only runs with AC on


Cooling Fan Temp Sensor is the First thing You Check (with what you have described) Cooling Fan Should ALways come On When The A/C is turned On as A/C Adds A Load to Engine, If Temp Sensor is Faulty it Will Not Give GROUND Signal to ECM >For COOLING FAN >RELAY to Give ground and turn ON The Fan.
There ARE 2 temp Sensors that Serve Different Purposes 1 is for Dash READING GAGE & Or TEMP LIGHT the Other is For ECM or Fan Relay (SAME Thing) you Said>""can disconnect the sensor and fan continues to run" < This Leads me to think you Changed the Wrong One. Not Questioning your Skills Just Here to Help.
TEMP SENSOR FOR 3.1L V6 is Located upper RH rear of engine compartment, near exhaust system. Temp SENSOR for 2.3L Engine is Located in LH rear of engine compartment.
I Hope this Helps Lead you to a NON-OVERHEATING Pontiac.
Good Luck and Have A Great Evening. rejakwilson
