Car Forum / Chevrolet / Chevrolet Corvette / September 2007Problem with my 92
This probably has just popped up. When engine temp hits 200 degrees the engine shuts down. Something wrong with waterpump? Coil? I am lost. I can't say I've heard of that one, but many of these wierd faults are a result of a computer malfunction ... >This probably has just popped up.

Assuming there are no codes, one thing that happens at higher temps is the fan turning on... Computer senses the coolant temp and turns on the fan(s). The a/c also turns on the fans the same way -- signal from the a/c to the computer which turns on the fans. What happens when the a/c compressor kicks in?

I guess I have to check ECM >> What happens when the a/c compressor kicks in? >> [quoted text clipped - 3 lines] > Nothing. Temp keeps going up until it hits 200 then engine shuts down. > I guess I have to check ECM Hmmm. I didn't ask the right question. Did the fan run? Signaturepj I think the auxiliary fan kicks in at 227 degrees. My money is still on the computer. >>> What happens when the a/c compressor kicks in? >>> [quoted text clipped - 6 lines] >Hmmm. I didn't ask the right question. Did >the fan run? Just talk to the mechanic and he said both my fans are conking out. They work intermittantly. Going to have him replace both fans, put in a lower thermostat, and burn another chip for the thermostat. |
