I have a strange problem when my car's engine is running when parked in one spot. The temperature starts to rise after running the car for about 30 minutes. Usually the fan will start kicking in even if the car is off right? I am trying to pinpoint the problem. No signs of leak, coolant is at max, all fuses seem to be fine. All signs are pointing towards the fan. I don't know what else it could be. If it is the fan, will it be an easy fix, or will it be something expensive that the dealer will have to charge me?

 

Fan should turn on when the AC is on.

 

Well if that's the case, my fans seem to be working. When I turn on my A/C it is blowing air into the cabin. So what could the problem be? Why isn't the fan automatically turning on when the engine temperature starts to rise?

 

The radiator/cooling fan, not the blower. The blower blows air into the cabin, the radiator/cooling fan blows cooler air through the radiator to cool it.

 

since when does the fan run when the car is off? mine doesnt do that

 

To what level does it rise? Halfway is normal. Exceeding halfway is not normal. Which fan are you talking about. The radiator fan is run by a clutch, which only kicks in when the car is running. If a fan is kicking in after the car has stopped, it's the condenser fan for your AC that's running.

I'm a little confused by your question.

 

It starts to rise to towards the Hot level, maybe 85%. Is the radiator fan the one that cools the engine as well and cools the engine when the engine starts to get hot?

 

You have air in your system most likely. You can bleed it with the bleeder behind your engine bay on the passenger side. I've never done it, but open that port and then turn the car on. Pour in coolant into your radiator until you it comes out of the bleeder port. Otherwise your thermostat may be bad too, I highly doubt it has anything to do with your fans.

 

Actually...the bleeder valve should be closed when you are running the vehicle. You need to fill the radiator to fill level and coolant reservoir. Then open the bleeder valve and fill radiator until the fluid starts to spill out of the bleeder valve.

Run the car until warm. Repeat process until there is no air coming out.
