Redline Detection 95-0700 SmartFit Universal Cooling System Test Kit with Pump

I ordered this coolant pressure tester because I was helping a friend find a coolant leak on his 2015 f250. Installed it to the primary system easily and it fit good. I like how it's Universal just pop it in and twist it till its tight. It pumped up quick and the accuracy on the pressure guage was spot on. The tool its self did not leak but I did find the leak on the thermostat crossover gasket. Pretty awesome. It's well worth the money and it's a good tool to have in the tool box.

Well made, did the job perfectly

I've used it several times, it works and still works.

I took a chance on this tool and am glad I did. This is a "universal" cooling system tester that probably works on most automobiles and light trucks. It comes with three adapters to fit a range of filler neck sizes and relies on screwing the adapter together tightly to expand the rubber plug in the filler neck and establish a good seal. The largest size worked for my Chevrolet Corvette after I figured out how to get it tight enough to stay in place. It slipped out the first couple of times I tried it. After I made sure that the rubber adapter and the filler neck of my overflow bottle were completely dry it worked. I also used a rag to firmly twist the adapter to maximum tightness while maintaining vertical pressure to keep it seated in the coolant filler bottle. That worked and the adapter held 15 psi for 40 minutes, good enough to confirm my cooling system is sealed. It comes with nicely printed instructions and a parts list which describes two o-rings and a washer but I did not see them in the kit. The tester worked fine as shipped. I was very impressed with the quality of this test kit. The fittings are well made and sturdy, the gauge and pump feel solid, and the pressure line looks to be very durable. The blow molded case is nicely designed and holds everything securely. I'm glad I purchased this tester.
