Electric fan thermostat


try this.. turn off the heater and let the car idle.. wait until the fan comes on.. if it does not come on before the guage pegs over extremely hot(you will smell antifreeze) then you have a water pump issue and/ or thermostat/ cooling fan relay issue.. if it does come on and cool down..use this as a base reading for this car as long as everything works fine..

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.

Does the fan not come on at all, or not until the temp is above 230 degrees ? And do you know if the computer is sending a ground signal to the relay at 220 degrees ?

Cooling fan motor does not engage while idling


If the fan runs when the ac is on, you can assume the fan motor and relay are ok. The temp sensor signals the computer when the engine reaches 220 degrees and the computer grounds the fan relay to power the fan.
You would need to check the operation of the temp sensor and verify the engine temp, usually with a scanner.

Where is the fan temperature sensor located


actually, the ECM directing the sensor to actuate the switches. the engine thermostat is the actuator of the fans in the cooling system. and its located in the oulet port of the engine where the upper radiator hose is connected. (and or at the lower rad hose, some design on VWs).

Replaced fan and relay and temp sensor ran car for 20-25 min temp only hit 220 fan didnt come on. when i turned on ac fan came on and once i turned car off fan didnt turn on is there another problem?


The fan should come on between 217 and 223 degrees. That is normal operating temperature when the computer sends the signal for the fan to operate, Did you bleed the cooling system after you replaced the sensor?

Thermostat temp guage goes to 220 degrees


220 degrees is normal operaing temperature for your car. The thermostat does not open until 195 degrees and the fans don't come on until 126 to 128 degrees. If it gets over 129 degrees and the fans have not turned on then the cooling fan system is the cause of the problem. (cooling fan, cooling fan temp switch, cooling fan relay, etc.)

the electric cooling fan for the radiator will not turn on when the engine reaches normal operating temp, its only supposed to come on if the engine temp goes over the normal temp. (around 220 degrees)
it is normal for the fan to come on any time the a/c or defroster is turned on.
