After like 2 weeks of changing my thermostat on my 01 Maxima, My Radiator fan comes on after warming up and does not want to turn off. It dosn't bother me that much, but its really loud.
Here are a couple of things that i think can be the problem, The thermostat i bought at autozone is not opening, or the coolant i put in after a bit of spilling during the time i was changing the thermostat is a different brand and kind of coolant that was already in the car, if that matters. The one that was in the car was green and the one i put in was clear.
Can anyone Suggest anything?
-Thank You

 

Find out the actual coolant temperature. I remember mine staying on most of the time in the warmer months, and it will always be on with the A/C.

 

Could be air in your system.
The fans turn on when the coolant temp sensor reads Iirc 200 degrees.

I would drain and refill the system with new coolant

 

Yes there is air in the system. Open the radiator cap, raise the front on ramps and run the car for 15min. All air is out

 

Fixed, it was the thermostat, the auto zone one was a peice of crap, bought a new one from the dealer and it works like a charm.
