1996 Grand AM, 3.1 engine. Radiator fan does not come on. Checked fan motor and it checks out OK. Replaced sensor by the thermostat for fan control. Temp gauge works OK. On the highway (55mph or...


check you're fuse's for the fan. At highway speed's there is enough air flow for the radiator to cool the motor. If not run the fan from a switch from battery to fan as a last resort.

1993 RX7 - cooling fan always comes on when engine is shut off.


I would want to know if the computer is grounding the fan relay to make it come on, or if the relay is faulty. On some models the computer turns the fan on to keep the radiator from overheating when the engine is stopped, but that should only happen with the engine at operating temp.

if the fan electric fan is not comining on, you need to check the fan motor to see if your motor is bad on the fan. check it by running a hot wire directly from your car battery to the fan elecrtic plug.

Fan keeps running after car is turned off? Sensor or relay problem??


Some cars are designed to have the fan run for a few minutes after you turn the car off. But if doesn't stop until the battery drains, then it might be a faulty switch or temperature sensor.

Or, if the fan stays running when the engine and radiator are cool you have a very cheap problem: The fan thermostat is stuck closed. A new thermostat will fix the problem--the hardest part of replacing it is finding it. Follow the wires from the fan to the switch--it is usually on the bottom tank of the radiator. Drain the radiator first and save the coolant to put back in after you replace the thermostat. NEVER OPEN A HOT RADIATOR.

If that wasn't it then check the following:
  • Check to see that your coolant level is correct. Top up as necessary.
  • Lay your hand on the radiator (with the engine off) and feel if it is as hot at the top as it is at the bottom. If not, your radiator may be clogged and need flushed or replaced. (Flushing is cheap. Replacing the radiator isn't)
  • Do you get heat from the heater? Leave it turned on high and see if your fan stays running the next time. If it takes care of the problem that could mean you have a kinked radiator hose.

Hope this helped (remember comment and rated this).

Find relay and give it a tap, to see if that helps. Not sure on that if its along drivers fender under hood or not, but listen for click from small 1"x1" roughly relay attached somewhere in engine compartment area, firewall, fender area.

Radiator Fan continuously running with engine off, discharging battery


It is not the fault: for long time Renault has that concept, that is to prevent engine oveheating when coolant circulation is suddenly stopped.

Radiator fan can continue to work up to 10 minutes after engine is off. You should worry about it only if it wouldn't stop even after 10 minutes.
