I got a 1986 GT that wont build any cooling system pressure and will run hot if the A/C is running. I have pressure tested the system to 16 lbs and it will hold it. I have tested the rad cap too and it holds pressure as well. What would cause this problem? I have a Summit H/D alum radiator, Mr. Gasket hi flow 180 deg thermostat, H/D clutch fan, factory shroud, bottom hose with the wire inside. I do have the heater core bypassed (do to leakage) with a loop.
Your wisdom would be appreciated. Thanks,
