So I picked up a pressure tester from auto zone. As everbody probly knows, it takes an adapter. They have no clue, which adapter it is. That shouldn't surprise me because they don't have the correct radiator cap either. They've got a number that's listed as being the right one, looks right, but it don't fit. So I need to help them find the right ADAPTER, for the tester. But it's a tool loan! I don't wanna go to someplace else, I'd have to buy an expensive adapter. So I'm hoping someone can hook me up with the right part number. Unfortunately it has to be an auto zone part number, or something they can cross reference. The car is a 2003 civic EX. I think it's a 1.7 liter.Hopefully someone knows something that'd help. Thanks for looking.
