Need Help car overheating... I can not figure out why my 97 Z28 M6 keeps overheating. It is full of fluid, and i have replaced the thermostat. Also had the water pump checked out, and still no luck. My fans will only come on when i turn the A/C on, so i replaced the relay switch, and now they both come on fine. What do i do next????

flush the radiator and use some of that cleaner stuff they make for your car it's fairly easy you just add it along with water and run the car for 10 minutes then let it run out and add new fluid you might have a clog somewhere?

Yep, check the radiator. I just posted a thread about my experience a few mins ago. It might have some deposits in it. A radiator shop can "hot tank" it and clean it up or you might try what was mentioned above. I might take it off, lay it down, and fill it up with CLR or similar delimer and let it sit for a while. That way you don't send the deposits through the engine and pump.
