1996 cavalier overheating
A buddy bought a 96 cavalier with a 2.2 in good shape for 200 bucks. It has a remaned head, new thermostat, and I put a new heater core in for him. The radiator fan does not kick in and there is no heat to the cabin. I have warmed up the motor and bled both bleeders at least 15 times. The temp gets high enough that it boils over and just steam blows out of the bleeders. I have gone through 4 gallons of coolant already. I did a compression test and 2 cylinders are 180, 1 at 165 and 1 at 170. I have pressure tested the cooling system to 16 pounds and it will lose 2 pounds in about 5 minutes.
What am I doing wrong? Head gasket problem pushing into the cooling system?
