I recently noticed on my 03 Evo 8 the radiator fan keeps going on and off at idle and the cars not even over heating or anything...Is this Normal?

 

^^yup... My fan goes on and off all the time. The time my fan last off is only like 7-10sec (this is when my AC is on)

 

Sounds right to me. Usually just turns on and off once the engine reaches operating temp in order to keep the temps stable. It also turns on when you turn the AC on.

 

I dont have ac in my car rite now..fans so annoying!

 

Im talking like 3 mins after I start my car it goes on n then shuts off..then the cycle begins

 

Like others have said its just trying to keep the engine at optimal temps. If youre just parked and idling there is no air passing through the rad so the fan has to come on.

 

i have two fans like all the other evo's now my only concern is that the fan on the inside of the engine bay does not come on at all? is that an issue?

 

These cars are known for having fan controller issues too. As long as the fans are running, while it may be annoying, longer or more frequent operation of the fans will not hurt the car in any way since (when operating properly) they come on to help the car anyway, so at least you know the car is safe. It's when the fans won't come on at all is when you have to begin to worry.

ILoveAWD, you may have a concern that needs to be addressed as well. Do you have A/C in your car?

 

mine does the same, it is a bit annoying

 

not trying to jack a thread, but yeah i do have ac in the car my car, my car runs cool it is just that the fan inside the engine bay beside the upper intercooler piping does not come on. the one in the front does all the time though off and on.

 

One of your fans is related to cooling and is triggered by engine coolant temp and works in combination with thermostat function and flow through the radiator in order to keep the engine cool.

The other fan is directly related to A/C and works when the compressor is engaged. If you have the car running and turn the A/C on and off a couple times, with a few second interval in-between switching, you will hear the compressor engage and disengage, the rpms will rise and fall, and the condenser fan will cycle on and off depending on A/C switch position.

 

I had that same issue,changed the fan controller, and it went completely away.

 

Just test it by turning on your AC to max and see if it is turning on afterwards.

 

The fan in my IX turns on and off every few minutes. It turns on when I park. I let it run til the fan shuts off and then turn my car off. It goes on more frequently when you have the AC on.

 

Does your fan run in during cold start as well? If so its ur fan control unit.

Had the same issue fan ran like crazy on and off also when the car was off it would run for another 2-3 sec and then switch off.
