Radiator pressure test


Topic starter

2008 Honda Accord 170k. So to test for antifreeze leak, I bought a pressure test. When I used it, it went from 15psi to 14psi and stayed there for the next minute or two. Does this mean it has a leak? I didn't see anything on the floor except drops of oil due to small oil leak.

Well, if it stays stable at 14 psi I doubt you have any real leaks. If you have a leak it's going to leak with 14 PSI. That could just be a glitch in the gauge itself. But sometimes if the head gasket is starting to leave you can do that to do my video. How to tell if your head gasket is blown Scotty on YouTube
