Thanks Matt,

Cooling system pressure test ?

What would be a good target PSI? Would it be as simple as putting shop air to a heater hose?

Usually the pressure cap on the radiator is rated for 16 to 18psi.....with the cap off and a Stant pressure tester affixed you limit the test pressure to 25psi.

DO NOT put shop air to a heater hose as its way to high and you risk blowing out something else.....my suggestion is just go down to the your local parts store like AutoZone, NAPA etc as they usually have a tool loan program and borrow the pressure test kit.
