I also have had an overheating problem with my 93 Corsica, ever since I had the antifreeze changed about 7 yrs ago - ever since the temp sits from almost 1/2 to almost 3/4. I've been given every excuse under the sun of why, and 5 mechanics, a thermostat, radiator, new hoses, pressure test, new computer and a flush later, it is as hot as ever, if not hotter. I've ruled out the block and any leaks, and yet I've been averaging about a 1/2 gallon of coolant I have to replace about every two weeks or else it does overheat. I've had the computer tested and the fan sensor check to see if the fan goes on at the right temp, and stays on the proper amout of time.
My newest mechanic who replaced the radiator and did a flush thought he had it, but low and behold the very next day it lost a 1/2 gallon - he attributes this to evaporation from the hot temp. - I drive 16 hard miles to work on I295 in nj - which is stop and go constantly, and the car seems happy when I'm doing 60-70mph - but as soon as we stop and idle the temp climbs up to almost 3/4. I've had one mechanic try to tell me my gauge was wrong and that it wasn't hot at all - lol - needless to say, he's history - the gauge is correct.
With all that said, where is the coolant disappeaing to? and are we looking in the wrong places, I've heard alot of theories, - water pump only leaks while driving, so there's no trace of leaks, nah - ain't buying it - transmission is overheating - nah - don't buy that either, trans fluids are fine. - collapsing hoses, nope ! - dirty engine, ditto - engine's clean
well, at least I'm not the only frustrated Corsica owner
I'd appreciate any help you guys can give
Peace
