The coolant fan continues to run after the engine has cooled and then turned off. The fan continues to run and runs the battery down.
There is a sensor on most modern cars which turns on the fan when the coolant temperature reaches a certain value. If this sensor is bad, the fan may run continously.
unplug the coolant sensor and turn on the ignition without starting the engine. The fan will run.
Are you sure it is the condenser fan that continues to run? It is not uncommon for the radiator cooling system fan to continue to operate after you shut down, due to the fact that the coolant in the radiator is still hot. It is designed this way. Check to make sure you are referring to the correct fan.
Scenarios - from best to worst case: Poor engine cooling via fan or grill Coolant too low Coolant leaking Thermostat malfunction (stuck) Radiator is full of gunk Water pump malfunction
they are thermostaticly run.
Normal causes are low coolant and an inoperative radiator fan.Normal causes are low coolant and an inoperative radiator fan.
coolant temperature switch turns on the fan, if the fan isn't running the car's overheating...it's a sensor mounted in the coolant line that detects coolant temp.
The computer uses the engine coolant temp sensor to decide when to run the fan.
The car has an electric cooling fan that is temperature controlled. The fan will sometimes run for a while after the car is turned off to help cool the engine. If the fan doesn't stop after 20 minutes, then you can start looking into problems with the relay, or the coolant temperature sensor.
The fan motor is controlled by a thermostat. When you turn off your car if the water temperature is higher then the thermostat is set for. the fan will continue to run until the temperature comes down then shut off. If the thermostat is faulty the fan will either run continually or not at all.
No its not that easy of a job and if you continue to run it this way, then you could damage the engine.................
