I have a 02 Ecotec Cav. I have a Brand New Fan an motor. New Fuse or relay. an tried the Jumper wire. Still nothing....

But on the Tranny there is a Threaded bolt. What all is suppose to be on that Bolt? I have three wires that are on that bolt! i have the Negative some other wire that i have no clue of what it is. an one that holds the Wire harness.

I let the car heat up. still nothing. I check the Fuse in the engine bay an it's hot??? is something grounded thats not suppose to?

i know that the threaded bolt on my 3spd auto is for a grounding location. probably your problem there, check your grounds and connections.

Hmmm ok thanks... I tried taking a wire off an still nothing..

well, i'll let the guys with more knowledge on these cars help ya. I only know certain bits about these cars, trying to learn still. Only thing i can think of is just to check all of your connections and wires.

Might be a blown rad fan motor itself?

Did it just stop working suddenly?

If you run direct power to it Ground and Power and it doesnt work might just be the motor

you said you have a new motor right? Maybe you could replace the temperature sensor (they are fairly cheap I believe) and see if that helps. Is it throwing any codes?
