Product Description
9xmarine is proud to offer a water jacket pressure tester designed for all engines equipped with a 3/8 NPT thread temperature sender.
Operation is simple:
-
Remove your existing temperature sender.
-
Install the tester in its place, using Teflon thread sealant for a secure fit.
-
Apply air pressure up to 15 PSI to the one-way nipple on the opposite side of the tester.
-
Observe the gauge needle. If the needle remains steady for at least 30 seconds, your engine's cooling passages are properly sealed. If the needle begins to lose pressure, it indicates a compromise in your engine's cooling system.
While your cooling jacket is under pressure, you'll be able to observe any air hissing or water leaks from specific locations.
We assume your thermostat is properly installed and not broken. However, we also supply you with pipe caps to help isolate your water distributor head for more precise testing.
