JIFETOR Radiator Pressure Leakage Tester and Vacuum Cooling System Purge Coolant Refill Tool Kit, 28PCS Universal Automotive Water Tank Leak Test Detector and Pneumatic Vacuum Coolant Change Set

I've gone through 2 of these kits. the spring loaded metal caps (the 3 you see in the bottom left of the case) are not strong enough to seal against the inner rings of a radiator or their own adapter above about 10 PSI. This means if you try to pressurize a coolant system, or use their cap adapter, you can't get above 10 PSI before the cap itself starts to leak. (Yes, I did them wet) This also means you can't test most radiator caps, which are supposed to open above 16 PSI. Additionally, since the quick connect fitting is part of the backing for that seal, if you apply any minute lateral force to the connector through the hose while trying to pump, that causes it to leak more.

this kit is the envy of my co workers. it fits everything from volkswagons to toyotas. the vacuum bleader is amazing and the tester is exactly as good as any other I use. This has paid for istself in 1 month of use. BUY THIS KIT.

I was suprised at how many styles of connections it has even for use on heavy duty trucks/semis. i didn’t use vacuum feature but pressure test feature saved me a lot of money both to diagnose and then to verify repair fixed problem before pulling out of garage.

This product is a very nice addition to my home garage. I fix cars as a hobby. This has come in very handy a couple of times already. If anything goes wrong, I'll update my review.

very cheaply made #3 cap bent first time I used it causing me not to be able to pull a vacuum or be able to refill the radiator. very disappointed. Matt
