View Full Version : Overheating
05-11-2003, 04:41 PM
My 93 Z28 is averheating, and I can't find the problem. This is my second 93, the first one i sold. Anyway, i changed the stat, and while it was bad, it didn't cure the problem. It looks like the cooling fan isn't coming on. Anyone know where the relay is for that fan, and where i can get a new one? Hopefully that will work.

Anyone? I'm totally lost on this one.

It is normal for our cars to vary in temp, but the fans should come on and cool it back down. I would check into the relay like you suggested. Or check your fuses. Don't know where the relay is located though.

I have a 95 Z and my car does the exact same thing. I have had it checked out and they didn't find anything wrong with my cooling system. But mine still overheats too. All i do is turn on the defrost on high and roll down the windows and that drops the temp back down to normal. I dunno if it will work for you but it did for me. Good Luck!!

The relay is located in the PCM (Powertrain Control Module),at least it is on a 94, should be the same I guess. I think the Engine Coolant Temperature Sensor (ECT) is on the Engine around the water pump somewhere. I haven't been able to directly identify it yet. It tells the PCM to turn on the fans.

hey in the engine department there should be a fuse box if it is the fans it could be your fuse is burned. anyways in the fuse box the should fuses with numbers on top and the fans it should say 25 wich means 25 amp and it should be clear and small. so go to kragen or any little shop like pep boys and get that fuse you should need 2 of them ONLY THOSE YOU CHANGE NOTHING ELSE.that what was wrong with mine i did everything you did and that was the problem. dont fill the recovery tank to the neck even when its not hot or over heating it will still spill when on TRUST ME:D
