just let the engine cool overnight, then unhook the battery and that sets the computer.. dont idle it drive it, come back bleed the air out. it should be alright..

i have already tried letting the engine cool down overnight and bleeding the air out but not disconecting the battery.i will give it a shot tonight and let you know tomorrow what happens.

chris.. i dont know what to recomend.. you had the heads pressure tested and machined its not losing coolant.. and you bled the system, you repaced the temp sending unit.. your car shouldnt be hot..

Chris, I'm having a similar if not the same problem with my 95 Lumina. Do you ever get the Low Coolant light like I do?? I've replaced thermostat, water pump & had dealer replace lower intake manifold gaskets. When idling and you turn a/c on do both fans cycle o0r only Fan #1?? Did you solve it?? Doug

i replaced the temp cooling sensor and the car is running way better.ive got one more sensor to change to see if i can get it running better.im happy with the temp staying just over half but not satisified.i think this problem is finally behind me.lol.any questions feel free to ask or email me.
