RELD Head Gasket Tester Kit Combustion Leak Detector for 50 Tests

Worked as it said it would. Mine was bad news , a blown head gasket but still the tester was good.

This test kit was great. Great price , easy to use and quick results. I was hoping that the liquid would stay blue but it turned yellow right away. I wasn't really surprised with the results but it was good to see it clearly right away. So now I focus on the job at hand with the clear results!

Great item

Product works as it should! It proved to me that North Star engines do leak exhaust into the cooling system. Even the ones not overheating. Easy to use. Just unscrew your cold caddy engine radiator cap. Put the plug in. Add the blue juice and fire it up. It will only take a few minutes and you will see the fluid start to bubble. IF it changes color she got a blown gasket or crack. If not check the thermostat, water pump and radiator……

The media could not be loaded. Unfortunately it worked. Changed the color from blue to yellow. Atleast no more guessing just gassing 🥸

The liquid arrived green indicating that it has come into contact with co2 and it wouldn't be able to give accurate results. Thanks for wasting my money and my time!

great product it did change color it detected a leak

Well, I ran the test and it confirmed what I pretty much already knew. My head gasket is leaking. I'm still glad I did the test before taking the car in for repair. I just wanted to confirm it so I'm certain I really do have a leak before shelling out big bucks to a shop. The test was really clear and left no doubt- the color change was obvious and it happened in about 2 minutes of running.
