Overheating

ferndogg

My 2001 oldsmobile intrigues,is almost touching the H, I changed thermostat, water pump got it at auto zone, and radiator, even flush the radiator, bought blue devil engine gasket stopleak, and still overheating the oil looks good ,I see bubbles in reservoir, thinking there's. Air in system, so frustrating, also I see no leaks

Hello! I can think of two things right off that could cause this, radiator cap failure and a leaking head gasket. Have the cap and neck tested for correct seal, pressure, and operation, and the cylinders pressure tested. This will tell. Of course, without having the car here, I can't say for sure. Good luck...

Same problem, 99 intrigue, all new cooling system parts, but car overheats. Right now I'm thinking the engine runs too hot, or coolant leaking into engine.
