What is every possible cause of your 92 Camaro RS 305 TBI overheating?

Answer 1

I had this problem with mine. I had to hook the cooling fan up to a toggle switch, the previous owner didn't know what he was doing and messed up the wiring to the fan when he was working on it. I tapped into my radio hot wire and ran a toggle and live lead to the fan. Other reasons could be bad thermostat (doesn't open), coolant sensor not kicking in the fan, might even be bad coolant.

I found my overheating problem, and this should ice the cake for overheating issues on this particular Camaro. If you have a good fan, coolant temp sensor, intake and head gaskets, coolant, hoses, no leaks and consistent fluent level, good heat, and everything seems absolutely fine, you might have a problem with the physical guage itself. When I replaced my dash light, i played with my temp guage needle while I had everything apart, and indeed I found a "rough" spot in the needle. What I did was pull the needle to its 'outmost' position where i felt "smoother" operation, and put it all back together. Since then, my car hasn't overheated at all (it never was overheating to begin with!)

If your Camaro is overheating, I suggest getting a computer hooked up to your vehicle's computer and make sure your vehicle's computer says it's overheating. When I did that, I noticed my guage was off anywhere from 30-50 degrees. it never went over 200 degrees, yet the guage would say 250 sometimes. Luckily, playing with my temp guage needle fixed my issue, but I did fix a few leaks and put a much needed intake gasket on first.

Watch out for the Orange antifreeze... it eats the gaskets away!!!
