KOOPOOL 30PCS Radiator Pressure Tester Kit, Coolant Pressure Tester and Vacuum Refill Kit for Automotive Cooling System Water Tank Leakage Detection

Works perfectly for the intended purpose. The quality is great for DIY maintenance. It paid for itself with one use on my car. I am looking forward to using this on my truck next week. Could not be more pleased with my purchase.

Fast delivery. Has fittings for most radiators in various vehicles

I use it whenever I can remember I have it

Finally used this kit for the 1st time, & it worked well. The only reason I gave it a 4 is because the instructions aren’t exactly for the kit I bought. The picture on the front matches the kit, but the picture inside for the list of fittings per vehicle doesn’t match the kit. And the instructions aren’t exactly very “simple.” Example- says my car is 28-6, but when you look at the diagram/picture, none of the fittings are labeled with the “28” prefix. Just 1,2,3,4,…. And those are for newer cars more than likely have the screw caps like on the surge tanks- not the traditional radiator caps. There are only 3 sizes of the traditional caps. Fortunately, it’s not rocket science. If you have a traditional radiator caps like mine, just match it up with 1 of the 3 in the kit. The pump hose is easy to attach & remove . But one word of advice- if remove the hose connector from the tester cap & it has pressure on it, be sure to press the relief valve/button before removing! Yes, fluid will come out with the air, but if you don’t relieve it fully before removing, expect to get sprayed!!!! lol I forgot & I fluid sprayed shot up out of the connector all over the engine. But Ll in all, it’s a pretty good kit, especially for the price. And the case is pretty organized & fairly sturdy. Decent snap clamp/clips.

The instructions are really bad, making the product a non-starter for me. Photos in the instructions were small and of extremely poor quality, with the verbiage written in some sort of Pidgin English that made little sense. I returned the product for this reason.

Works pretty well. Good quality for the price. Lots of adapters for all makes and models.

Great kit, worked on my 2007 Chevrolet Silverado Classic 2500 HD LBZ 6.6 Duramax. I bought mostly as insurance for changing out the engine oil cooler. The last thing wanted to do was reassemble then fire it up to find water leaks. This tester allowed testing while vehicle was still disassembled. Also used the air driven vac device and it worked great. But I would suggest that you make a valve assembly with air unions to connect to the air inlet. All of the parts are great quality parts fit right in the container.

Great set of radiator pressure tester, have not use it yet but it seems to be of good quality plus it has the coolant vaccum filler
