Car: 1996 9000 Aero
Issue: Coolant expelled out of coolant reservoir at cap
Analysis: Suspected head gasket so took the following steps to confirm. Checked torque of head bolts, all appropriately tight. Checked for exhaust gasses in coolant, none present. Checked temperature of coolant while driving, 215-219. Pressurized coolant system to 18psi, held pressure overnight (including cap). With pressure gauge connected to cooling system, measured 2-4psi at constant speed, any rpm. When boosting, pressure immediately rises in cooling system.
Question: If the intake system is pressurizing the cooling system, why doesn't pressurizing the cooling system result in loss of pressure overnight into the intake system, or anywhere else? Is there any other place besides the head gasket where intake pressure can pressurize the cooling system? What is my problem and how do I solve it?
Thanks.
