radiator pressure test questions (1 Viewer)

Good question... just keep pumping it up and pay close attention to the psi as you do it. When something blows up, that’s the max amount of pressure.

In all seriousness though, you don’t need to go much past 16-17 psi to find a leak. Just pump it up to 17 psi and let it set for awhile and keep an eye on the meter. If it goes down, give it the fat girl treatment and look for the wet spot. If there is no wet spot... you have a bigger problem. If it stays at 17 psi, you’re good to go.
