Unfortunately the coolant pressure test kit I purchased did not have the right cap for my truck (2006 GMC 2500HD). This cap fits perfectly & keeps the pressure.I’m trying to find a mystery coolant leak.

Simply a perfect match for pressure testing late Ford’s with 3.5 and 3.7 V6 engines. A must to avoid condemning the water pump when it’s not your issue. No leaks and feels solid. Made with heavy gauge plastic and corrosion resistant metal quick connect. Works great with Astro pneumatic cooling system pressure tester.

This fit my 2005 Ford F150. It's exactly what I was looking for. I tried everything else I could find on the Internet but they didn't fit. So if you have a 2005 F150 4x4 Lariat, this will fit.

I used this on a 1995 Saturn SC2 to check cooling system integrity.Connects snugly to the Astro Pneumatic compressor driven adjustable pressure manifold.Can't test the cap as it replaces the cap but does what it's designed for.And can be purchased as a single cap or as part of a set. Most DIYers don't need a full set.
