Reply to "Suggestions or advice for pressure and expansion tank caps"

lf-tp2511Member

Pressure tank OEM cap was 13 pounds, but most of us are using 16 pounds.

Expansion tank does not take a pressure cap, just a plain cap, often found on the cheap plastic overflow tanks sold at auto stores.

yes, some of the tanks did have European necks which generally need European caps to properly hold pressure. But if your car has previously been running fine with the caps you are replacing, just find matches for those caps.

this article has good information on the different types of caps:

If you use the search tool on this forum, you will find more information.
