Can't call it a radiator cap cause it's not on the radiator. Anyway the cap on my 96 had bad gaskets but the gage was reading in the N range. The pressure would not stay long after I shut it off. I wonder if the pressure was stable when It was running. With the new cap I hope I don't find leaks. Will take a ride today to find out.

 

I think I just cut some rubber sheet and replaced the NLA gasket.
