I changed the water pump. thinking maybe trapped air?? cannot find pressure release valve. please help.... theres also no signs of leaks of any kind with head gasket. why is it overheating????? it has new water pump, new radiator. no leaks from gasket...?????? it a 1995 Oldsmobile Aurora 4.0

There is no pressure relief valve for the cooling system. The Northstar engines are basically junk and when you have an overheating issue, it means the heads are gone. Either buy another car, or get yourself another engine (although that won't be much better). You'll sink thousands into that crapbox to fix the overheating issue and it's probably not worth it. Good Luck!
