RELD Head Gasket Tester Kit Combustion Leak Detector for 50 Tests

Good product, simple . Why spend more ? Good simple cheap does job as good as fancy ones

Worked very well! Easy peasy!

I wanted to be sure my head gasket wasn't leaking. The rubber cone didn't fit into RAM TRX 2022 coolant tank very well. I saw no fluid color change with engine running. I tested fluid by exhaling three times and got significant green and yellow color change. I'm certain my head gasket is fine.

Works as intended. I was 99% sure I had a head gasket leak due to air being introduced into my cooling system and I used this kit to confirm before ordering parts. Tips: Use the test for at least a few minutes. And green also means you have a head gasket leak. Green is the color you get when you mix blue and yellow. Yellow is a strong result. I have a slow leak and it takes a few minutes for my test to turn green. If I would have quit after a minute, my test was still blue. I was concerned CO2 was entering the tester from the ambient air since I could smell my exhaust, so I dumped it out and retested with my finger over the top with light pressure to still allow bubbles to escape and got the same results. The rubber tip is universal and didn’t seal on my Honda Accord so I had to hold it down, but this can be corrected by cutting the rubber cone shorter to seal the outer edge of the radiator opening without bottoming out. And make sure your coolant is low enough to have room to expand with heat without going into the tester or you’ll have a mess. And I thought the kit was made in America because of the American flag in one of the pictures, but it’s “made in EU”.

Excellent product, easy to use and it takes only a small amount of chemical to perform the test

Works great

Very simple and easy to use. Put it on a cold engine, sealing the overflow tank and started the car up, let it run till the pressure in the cooling system started to build and push into the clear cylinder before turning the car off. Unfortunately this test confirmed the worst and an additional confirmation from a certified BMW tech after getting these initial results, validated the engine has a major issue..

The rubber corks do not fit my nissan versa note radiator. They are to big

Worked as described from blue too green .....

Tester validissimo

Der ELD Zylinderkopf Dichtung Tester ist wirklich praktisch und einfach zu bedienen. Ich konnte schnell prüfen, ob die Zylinderkopfdichtung in Ordnung ist. Das Gerät wirkt robust und ist für Autos und Motorräder universell einsetzbar. Die Handhabung ist unkompliziert, und die Tests liefern klare Ergebnisse. Auch die Tatsache, dass man bis zu 50 Tests durchführen kann, macht den Tester besonders wirtschaftlich und zuverlässig. Fazit: Ein toller Tester, der genau das tut, was er soll. Absolute Empfehlung, wenn man die Zylinderkopfdichtung selbst prüfen möchte.

The bottle had lost 10-15% of its contents during before it arrived and the liquid was not blue anymore. Color was dirty and almost looked like the liquid had reacted allready. Price was cheaper than many other products, but I reccoment spending that little extra for a better quality kit

Marche assez bien, pratique pour vérifier le joint de culasse
