Prokomon 15 Pieces Coolant Pressure Tester Kit; Radiator Pressure Tester; Cooling System Pressure Tester Kit

This is a great little set that will fit almost any coolant cap. The pump is little bit hard to compress due to the small knob but it makes finding leaks sooo easy. It saved me a lot of time and grief. Also you can’t beat the price for the service you’ll get. I found the sneaky leak in our BMW E60 in no time.

Works great. Helped identify a cracked block.

Other than the caps being just a bit touchy this is a great buy for the money. Be carful not to have any sideways pressure against the tester caps or they will leak down and give you the impression that the system is leaking rather than the cap. Otherwise the pump and gauge works perfectly.

If you have a leaking coolant system on the car, this kit is a must! I had been tracking a leak that was in a weird location and this kit proved that I needed a new radiator. Not just a hose. I also used it again after paying for a new radiator to ensure that nothing else was leaking.

Worked well to help me find a leak in my system, easy to use.

I have 3x 2005 Toyotas. The cap for 2005 Prius barely stayed on (too tight); it would pop off and took extreme force to get it not to (but even so, it wasn't fully screwed on, rather "on the edge of popping off"). I did manage to perform a pressure test with this tenuous lashup (the good).The cap for 2005 Sienna fit better, but I could not connect it to the pump-gauge hose due to lack of clearance above the radiator cap (it's under the windshield-wiper-mechanism housing); this kit, with its many parts, does not include a right-angle adapter which would have allowed the pressure tester to be used in this tight-quarter situation. And since there is no documentation on what type of quick-connect fittings this system uses, even if I was willing, I'm not able to build one myself without bodging. More nit-pickingly, the adapters I used do not snap positively into the provided blow-mold case; the ones I used had to be jammed in with extreme force, and even then, still wanted to pop out on their own.

I found a coolant leak on my Camry. Fairly difficult to find with just a naked eye. This product cut my time and expenses in half, at least. By the time that I figure labor costs and diagnosis fees, this little kit has already paid for itself Four times over!

Only got it up slightly higher than 10psi and it started leaking in between Cap and air chuck adapter.

This is one of the Fastest and easiest ways to find a cooling system leak!I discovered were the leak on my car was in less than 5 minutes after opening the package and hooking up the easy-to-use tool.I've been hunting for that leak for days and carrying around, and using, so much fluid for top ups that I was avoiding driving on the Highways!I should have bought one a long time ago.

never try it yet.will try it someday look good

Looks fine Came on timeHave not had an opportunity to use

Bought this to test my for a leak in my 1988 iroc and it worked perfect. Saved me a lot of money going to a garage. Easy to use and had the adaptor I needed even though it wasn't listed.

Excellent productWorked perfectVery complete kit with lots of adapters
