The fan is controlled by a thermostat, it will (should) shut off by itself after a few minutes, after the engine has cooled down a bit.

If it continues to run after about ten or fifteen minutes (i.e., it does not shut off at all, and will run the battery down if you leave it overnight), then most likely the fan relay is sticking on, and should be replaced. Less likely is that the fan thermostat is bad.

But if it turns off by itself after about five minutes, this is normal and desirable, it gets some of the excess heat out of the engine.

Cooling fans continue to run when engine is shut off


This is normal. Cooling fans today are not turned by the fan belt but are run by an electric motor. The fan continues running until the coolant temperature is reduced

I have reno megane 04 my fan continues running when my car is not running i have had the air presureit has just happened again sensor replaced bu


Many cooling systems are designed to let the cooling fan continue to run even after shutting down the engine...however, this should only last for a minute or so...your owners manual may help. If the fan never stops when turned off this is probably a faulty resistor...may need a good mechanic to confirm which...Hope this helps.

When I shut the engine off the fan wants to continue running


Hi!!
Some vehicles when engine is hot, will continue to run until the temp. goes down. Check your owner's manual to see if your vehicle is one of them. If not, the Fan Relay may be getting sticky.
Good Luck!! A HELPFUL - 4 THUMBS - rating for this solution would be greatly appreciated. Thank you for using FixYa.

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
