Cooling Fans on Constantly
As soon as I turn the key the fans go on. I know this can't be normal. Can anyone tell me how to fix them? Thanks!

Re: Cooling Fans on Constantly
Either there is an issue with your fan switch (located pass side head between #6 & #8 spark plugs, or a previous owner has hacked up the wiring to make them run constantly (probably because an issue with the factory fan switch).

It could also be the relays themselves, but I'm not sure where they are on the camaros. I know they were near the radiator on my 88 GTA though.

Exactly what happened to mine. All because the sending unit wire got charred.

Re: Cooling Fans on Constantly
The 'hacked up' wiring is definetly a possibility. It looks like a plate of spaghetti inside there. When they swapped out the engine there was no thought to making the wiring easy to follow...it's just 'there'. 
Thanks for the suggestions, I'll check it out tonight.
