Trying to sort out a cooling system problem in my Factory Five Cobra.
Stock 5.0 & Mustang radiator, longer hoses (Mostly metal to avoid hose collapse), and a replaced water pump.
Car does not leak, but will lose coolant & overheat, takes longer when I put on a 20lb cap. Cooling system pressure check holds pressure, drops very slightly over time. Compression on the motor is good, and it does not increase cooling system pressure when running (as far as I can tell).
So, I am trying to eliminate all problems, down to either a head gasket or bad water pump. Coolant flow is in the right direction, but lots of air in the system, can't get a good fill.
So, what's your take? Wrong rotationg water pump? Head Gasket? I'm stumped.
Thansk for your usual great help!
