Re: 95 z28 Overheating
Probably would have been a good idea to continue the discussion in this thread:
You indicate the problem occurs when the engine is idling, but then you indicate you have to "pull over". Does it also overheat at low speeds? ... at high speeds?
There are 3 fan relays - have you checked them all?
Have you checked the fusible link in the power supply to the fans?
Do the fans come on when you switch on the A/C?
In your earlier post, it seemed to be hitting 260*F while driving, because you said you couldn't answer GaryDougs question about whether the fans were running. Now that it's overheating at idle, have you verified the fans are in fact running?
Have you scanned it for codes?
Has the water pump ever been replaced? How many miles on it?
