What is the possibility of drawing in air into the cooling assuming the head gasket is not blown.
I just had the radiator re-cored and head gasket leak down test indicated no gasket failure (according to the shop, but will perform another test myself to verify).
I'm hearing an abundance of air in the heater core driving locally. Start, stop, turn, etc. At highway speeds all is well. Temps are remaining below 195 w/ A/C on but I am concerned about over-pressurizing the system.
Assuming the system is bled well and no head gasket leak (which otherwise would be the easy answer), where else can air be introduced into the cooling system? Is it possible to draw in air via a less than perfectly sealed hose connection without leaking coolant while parked? Upper and lower radiator hoses are either new or less than 2 years old.
