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

This radiator pressure tester kit comes with a large assortment of adapters, which makes it useful for working on a variety of vehicles. I’ve used it on a few different cooling systems and was able to find the correct adapter without much trouble. The connections seal well and the pump builds pressure smoothly. The gauge is easy to read and it held pressure consistently during testing, which is exactly what you want when diagnosing cooling system leaks. Everything stores in the included case, so keeping the pieces organized is straightforward. Overall it’s a solid kit for anyone doing cooling system diagnostics, whether in a shop or at home.

Worked great, I had another kit before from ebay but it always leaked so I threw it our, this one is superior in quality.

Great quality for the money, durable, has multiple varieties of sizing, and easy to use. Recommend !

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 product was as sold. When I opened it I was able to identify the one I needed quickly. I used it on a Volvo Penta Marine Engine and it fit perfectly. It arrived on time and in good condition.

I tried a loaner tool from a local auto parts store only to be disappointed that neither the pump worked correctly nor did the fitting attach to the cooling system overflow tank for my 2000 Ford F-150. I purchased this somewhat skeptical. Much to my pleasant surprise it fit! The pump worked well and proved to me that my system no longer had a leak as it was able to maintain a steady pressure. It's a great value compared to other kits and seems like it will fit many makes and models of cars or trucks so it's very compatible. It was super easy to use and did not require any instruction as you can either figure it out in your own or watch a YouTube video if you're totally clueless. I can't speak to the durability yet because I just got it and have only tried it on one vehicle. However the quality seems like it will be sufficiently durable for a home mechanic.

Seals are junk, leaks around the cap where it seals to the radiator.

Rivals "name brand" - think snap on, matco, etc; This kit is a GREAT value and quality made. Used by a 20+ year experienced Auto Tech. Has every thing you need regularly, and a few you only need for special circumstances ( think older model vehicles, odd ball foreign and domestic vehicles ). You wont be disappointed!
