Pressure test

One last thing I wanted to re-check was a pressure test of the cooling system. Basically here a used a borrowed snap-on tester. It replaces your radiator cap and with a hand pump you pump up to 20 or 30psi and leave it pressurized for 30 mins. and see if there is any change when you return.

If there is a change then you cooling system has a leak (head gasket).

Mine had 0 psi of change.
