Thread: Radiator Coolin Fans not working

My coolant climbs like s*** in about 10 mins of the car running the car reaches 200 degress the it has enough coolant no low coolant light... check the fuses for the cool fan and they are fine any other ideas wiring? Any alternative thanks!!

I'll check my connections but they are ziptied down so dont think that could be it.. any thing else to check for?

You are right it isnt but it shouldnt climb that high in 10 mins 20 mins it might be close to overheating.. plus my fans arent working so my motor doesnt have a way to cool itself..running and bill my pcm is a stock pcm programming

let it sit and the T stat should open

I'll burb the system while the engine running and bleed and watch the for bubbles

Help me understand why you think the fans should come on at 200F? That's how I read your post. Did I miss something?

If your temperature didn't warm up to the thermostat temperature in 10 min, you would get a code for coolant not reaching temp fast enough. The only thing I have found that heats up a motor fast is air in the system and or a problem with a water pump.

Really not seeing the problem in what you have said....

I just thought it was odd for the motor to heat quickly in so little time didnt know my fans turned on at that level so thats news to me i just need to bleed/ burb the system then... thermostat is 180*
