Why does my Chevrolet Camero Z28 overheat?

Answer 1

There are numerous reasons for overheating. The thermostat could be stuck closed. You could have a leak. You could have a blown head gasket which could be determind by a block test. The list goes on. Take it to a shop and have it pressure tested. Guessing will only cost you money on not finding the problem. I had the same problem and after trips to a couple of respected auto repair shops with no fix. I decided to sit the car for awhile. When I was ready to tackle the problem again, a few months later, my battery needed a charge. After removing and charging the battery I decided to clean the battery tray prior to replacing the battery. While cleaning the tray, I noticed the reservor hose, which runs from the radiator to the reservor and snaps into the battery tray (two piece hose aluminum and rubber with an aluminum clamp) was bloated. Upon further inspection I found that it was also leaking. I removed the hose and separated the rubber from the aluminum by breaking the permanent clamp. I then repaired the hose,by replacing the rubber portio with a 1 ft piece of 3/8" rubber reinforced fuel hose and two small SS hose clamps. This $12 repair solved both my overheating problem and my low coolant level sensor problem.
