I have a '97 Z-28 (I'm the original owner) with 120K. Recently I've had problems with overheating that I've not experienced in the history of the car. The "low coolant" light kept coming on and off. I took it to a mechanic and there was zero fluid in the radiator. He replaced the cracked water pump, leaking hoses, thermometer (twice) and flushed the coolant system. It is getting up well over 210 and sometimes almost in the red. The fan comes on, but it doesn't seem to cool the car down. It is particularly bad idling at stoplights or in stop and go traffic.

I read about a sensor for the cooling system, could this be the problem or what else would need to be replaced or checked?

Thanks for any help!

Sounds like he did the normal stuff. You might double check the thermostat as I believe they are different on the LT1. Also, please read through the tech forums as those guys know a lot about these cars. Welcome to the board.

Thanks for all of your help and suggestions. I am thinking it is either the wrong thermostat or the mechanic did not bleed out the air. This is the first time I've let an independent mechanic work on my car, all other work has been done by a Chevrolet dealer. So I agree that maybe he doesn't know the Z-28 well enough to work on issues like this. I know he did a pressure test so there were not any leaks. Also, I've heard another reason could be the radiator cap not being the correct psi. Any thoughts on this? Thanks again.
