Reld Cylinder Head Gasket Tester Kit CO2 Combustion Leak Gas Test Universal for All Cars and Motorcycles Petrol Diesel Block Rapid Engine Leak Detector for 50 Tests

"Saved me a fortune" I wasn't sure if my head gasket had gone after my coolent reservoir was empty on my van and heaters were blowing cold air. I called a local garage and they gave me a quote for an inspection which I could not afford. Then I saw this. Arrived in good time. I followed the instructions and turns out my head gasket is fine after all. This kit has everything you need for up to 50 tests. Value for money is excellent and the quality of the parts is really good. Functionality is spot on as it's a very easy to use kit. Highly recommend product.

Great item, does as described, able to check for head gasket leak, and many more to come as kit does multiple tests

Great product works exactly as expected and is perfect to verify Head Gasket condition.

I'm sure no one wants to have to buy a head gasket testing kit, but sometimes necessity demands it. I brought this kit to test the head gasket of my Rover 45, with a 1.4 k series engine, renowned for head gasket failure. I had seen some symptoms of gasket failure, so brought this kit to be sure before taking to a garage. The kit contains instructions for use, which are easy enough to understand, but a little vague in some areas. We were left wondering if we were doing the right thing at some stages. The rubber bung looks like it would fit a wide variety of expansion tanks, as it has a fairly significant taper. There is enough liquid for probably 30 tests. The liquid is supposed to turn green, or yellow after about 5 minutes if exhaust gases are present in the coolant system. Sure enough, after about 5 minutes then liquid turned very slightly green. The colour change was so slight that we were still not 100% confident. But the garage confirmed that even a slight change is a smoking gun. After taking it to the garage, they confirmed that the head gasket was blown. So this test is definitely accurate. Just not to be used as the sole test, just as a guidance. The kit is good quality, and does what it says, so functional.

I'm thrilled with the RELD Cylinder Head Gasket Tester Kit. It's incredibly easy to use, and the results are clear and quick. I was able to confirm the integrity of my head gasket with confidence, saving me a lot of worry and expense. The kit is well-made, and the reaction liquid works perfectly. Highly recommend this for its accuracy and convenience!

The Car I was looking at had a slight coolant leak. I wanted to be positive it wasn’t the head gasket. This non-invasive test “sniffs” for CO2 in the coolant at the header tank. Any change of colour it’s confirmed. If, as in my case, it stays blue and doesn’t change colour, it’s confirmed there is no co2 and therefore the head gasket was not a problem. Inexpensive Peace of mind.

I received it and all was good poured out the liquid and it was a light green from the get go. Regardless of that I tested with two vehicles exhaust gases before using in the cooling system. Both vehicles turned the liquid yellow one longer than the other. Tried on the cooling systems done what it needed. The only issue i had was the colour of the liquid as another I ordered was a deep blue and the green suggested a possible slight contamination. All in all if the fluid is the colour it should be it does work but it's important to remember if it doesn't turn it doesn't mean its not the head gasket.

Easy to use and cheap tester.

Dacht dat mijn BMW 325i n52 een lekke koppakking had. Dacht bestel ik dit maar om te kijken als dat werkelijk het geval was. Gelukkig geen lekke koppakking🥳

Works perfectly!

Worked as it should. I like the fact it takes very little fluid for each test. Verified exhaust gas getting into cooling system after other diagnostic procedures. You need to understand this is one of a few methods for determining headgasket & cylinder head leaks. Good value. Wish it came with more fluid.

Merci infiniment car ce testeur a sauvé ma twingo de la casse ou voulait l'envoyer le garage ...a ce jour, elle roule encore parfaitement. Utilisation du testeur et explications très simples et résultats fiables

I bought it to check a possible head fasted issues as there was a coolant loss in my Chevy Colorado. The test was negative, it didn’t change color and I left it for a very long time (30 min) just to make sure. I tested the liquid on a cup near the exhaust and immediately tuned yellow. I like that is compact and easy to use. I suggest removing a cup of coolant from the radiator to avoid mixing it with the coolant during the test (only if you are reving the engine).
