Cooling fans kick on for a few seconds then cut off


The fan should work off of the water temp. The fan will come on and off to keep the constant temp on the cooling water. If equipped with a second fan it is probably for the AC and will run when the A/C is on. If you think the fan should be on. Then If you know where the fan relay is check to see if it is hot, if real hot the relay may be going bad. Hope you know this when you turn the car off the fan can still come on if the water temp is to high. My thought fan going bad, temp sensor or relay may be the problem.. If you can touch the fan motor metal housing and it is real hot the fan man be going bad, remember the blades can start at any time.

Where can I get a cooling fan wiring diagram?


The cooling fans should come with a sensor and tells fans to come on at certain temperature

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.

2000 BMW 528i running hot


is the cooling fan cutting in ? run the engine whilst stationary with the hood up , give it a little gas 2000revs and wait for the temp gauge to rise ,the cooling fan should be heard cutting in , and off again once cooled the engine temp down ,this may take 10-15 mins but you have to be sure the fan is cutting in or you may cook the engine

Engine runs hot after a few minutes of running the car


That is very vague. Have you checked the radiator, and when it is hot does the electric cooling fan come on? Try running the A/C and see if the cooling fan comes on. Does it run hot on the highway or just in city traffic? I need some more details to try and narrow it down. There are many things it could be. Low coolant, stuck thermostat, air in the cooling system, bad fan motor, fan motor relay (also known as fan switch), or temp sensor.

Fan doesn't run while in idle and begins to over heat until I start driving agin then it cools back down to normal. Also the fan runs when engine is off and drains the battery.


The fan is only supposed to come on when there is excess heat .. in normal driving conditions it doesn't start. When you start your car in the morning the fan won't come on because the engine is cold.

With a hot engine - and it depends how hot the engine is - the fan will only kick in to prevent overheating. In heavy slow moving traffic or a traffic jam, the fan will kick in if needed.

The air flow through the radiator is usually sufficient -in normal driving conditions - to cool the engine.

When you park up and the car has a hot engine, the fan will kick in. This is perfectly normal. It is caused by a surge of hot coolant triggering the fan sensor. Perfectly normal.

The fan then should cut out after a while .. maybe 2-3 minutes at the most. If the fan runs continuously that suggests a fault in the temperature sensor switch.

Next time - wait by the car and see how long it takes for the fan to quit after you have parked up. It should stop of its own accord after a couple of minutes.

If the fan cuts off after a short while, and your battery is becoming drained, that's probably a battery or alternator fault.

Remember: when you start the car the fan won't kick in at idle speed because the engine is COLD, and there is no reason for the fan to start up ..
The fan WILL kick in for a couple of minutes after you have parked the vehicle and the engine is hot

1995 cutlass supreme. There are two cooling fans.


it will come on but only when the engine is very hot and the first fan cant cool it down that fast,, its turned on by a difrent heat censor so the engine needs to be realy hot to set the second fan running and it may even then only run for 30 seconds till the engine temp drops off,,, as long as the car is running in the normal heat range dont worry about it,,, if its cooking way up in the red,,,,,now worry about it,,fast too,,

My temperature gauge is malfunctioning, but the car does not run hot. What could be wrong?


Is it saying it is to hot?If so,and you know that the engine is not hot,replace the temperature sending unit.With ac off,engine running,make sure the cooling fans come on,and go off by themm selves.This will tell you that the engine is reaching normal temp,and when the fan cuts off,then it has cooled down.I hope this helps you.

The car over heats when cut it off


It is possible that your cooling fan is not working. First check that the wires going to the cooling fan motor are plugged in. If you have A/C you may have two cooling fans check both. If wires are good. With the engine cold start the car. Let the car run until the engine is hot. See if the fan comes on. If the fan does not come on the motor or the relay are probably bad.
