2003 Civic EX 1.7L.
What adapter is needed to hook up a pressure tester to the radiator on a 2003 Civic EX 1.7L? I borrowed a tester from the parts store that came with an adapter, but it's the same size as the radiator neck and doesn't "lock" on.



Advance's site says this should work, but it looks similar to the one I already have. Has anybody used this before?

That's definitely the wrong adapter. You should be able to use that to test a radiator cap, though... I think.

Anyway, here's a copy/paste from an old post of mine on the subject:

"Went out to Advance Auto Parts. Picked up the "PowerBuilt No. 70, 22pc Cooling System Pressure Kit. Model #940427" ($169.99 deposit). I think the SKU is 9150049. This has BOTH the adapter for the CAP (Adapter #10) and for the RADIATOR (Adapter #8). So if you want to pressure test both, you need to go to Advance Auto Parts, not AutoZone.

First tester I got ended up being a bum tester (hairline crack by gauge was letting out pressure... and coolant, lol). Returned to AAP, they called around and said they could get one from ~30mi away for me, but would be about an hour and a half wait. I came back 2 hours later, and got the replacement loan-a-tool."
