I have a 94 pontiac formula 5.7 LT1
I hope you can help I have put a new water pump, therm, and tried to bleed the system and still over heats. The car was sitting for a couple of years in a garage. Before I got it. I tried everything I can think of too get the air out of the system, or is there another problem. Today I started the car at idle temp was good as soon as I tried to drive it the temp rises and over heats. And I can not find any leaks I pressure tested the system. Please help im lost
