I have 93 z28 giving me overheating problems, I've replaced water-pump,thermostat, radiator pretty much all cooling sensors, checked the electric fans working fine, I still have overheating problems, i've been bleeding the air in the cooling system for a about month now, and i can't even drive over ten miles without it running hot. Also the heads in intakes manifold are brand new. Please any suggestions would help out alot thanks.

Please indicate the temperature that you are considering "hot".

Didn't understand what was brand new. Can you better explain what was replaced. How exactly are you bleeding the air out?

Some things to consider and check given you are indeed bleeding correct and are over heating. 1 check that you didnt swap the steam tube and overflow tube. 2 check for something blocking airflow of radiator. 3 be sure it was an lt1 thermostat(designed for reverse flow) 4 if its happening while driving be sure you still have the air dam. 5 Be mindful because a bad head gasket can be the problem and even become a problem. 6 ive heard of people forgetting to instal the drive coupler on the waterpump drive shaft.(not sure how the earlier models engage) Posted from Camaroz28.com App for Android
