You will need to do some testing to find the problem. When the car starts to run hot, ( near the hot zone) use a test light to check for power at the fan. if you have power at the fan and a good ground and fan does not turn on then fan is bad. the next test would be to check the upper and lower radiator hoses, both hoses should be hot, if only one is hot and the other is warm then replace the thermostat.
Back to the fan if there is no power to the fan then try switching out the relay with another relay to see if that helps.

When I turn the engine off the engine cooling fan stays on and does not shut off


depending on the engine temperature the fan is supposed to remain on after you turn the engine off, until the engine reaches a preset cooler temperature. when it reaches cooler temperature usually within 5 minutes or so it should cut off... if you cut it off and it is running 30 minutes later.. then there is a problem with the fan relay or temperature sending unit.

What temp should my golf run at if the cooling system is operating properly? Runs perfectly on the highway but when i stop start it goes from min temp to only half on the gauge but seems to be runnning...


the temp seems to be fine. 80degrees celsius or less in stop and go traffic is normal,especially since the cooling fans are working and coming on at the proper time. the what seems to be running rough is another problem that doesn't seem to related to the cooling system temp. may want to check the spark plugs for worn electrodes.

Car is overheating ...already replaced waterpump, flushed radiator, changed thermastat and replaced new water cap. there is no leak, and it over heats sometimes not everytime?


Hi!!
Make sure the small hose going from the reservoir to the radiator and the orifice at the reservoir are not clogged. If OK, check electric cooling fan system, specifically the Coolant Temp. sensor, Fan Relays and Constant Control Relay Module (CCRM).
Electric cooling fan system consists of a fan and electric motor attached to the fan shroud.
  • Engine temperature is monitored by the Engine Coolant Temperature (ECT) sensor.
  • Fan is controlled by Constant Control Relay Module (CCRM) with inputs from Powertrain Control Module (PCM).
The electric cooling fan is wired to operate only when ignition switch is in ON position and engine temperature exceeds specified temperature, or when A/C is on and vehicle speed is less than 45 MPH. During hard acceleration, the Wide Open Throttle A/C Cut-Off (WAC) relay controls the A/C clutch and cooling fan. A signal is sent to PCM and then to the CCRM, where the module de-energizes the A/C clutch and cooling fan, decreasing engine load during acceleration.
Good Luck!! A HELPFUL - 4 THUMBS - rating for this solution would be greatly appreciated. Thank you for using FixYa!!

Engine cooling fan not cutting in Peugeot 206 2002 Cooling fan and motor have been replaced with main dealer parts


Try the cooling fan switch, it looks like a large brass nut with wires on it on the thermostat housing or radiator.
To test, pull off the wires and connect together, turn on ignition and the fans should cut in.
If they don't it could be the relay, fuse or broken wire.
The switch is easy to replace, unscrew and rescrew in the new one. Connect the wires, not important which way the wires go, and refill coolant.
