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.

Excellent kit which comes with clear instructions and is very easy to use. The first test i carried out was on a recently acquired Audi which I suspected had a head/headgasket issue and the test came back positive (the liquid turned from blue to green within a minute or two). The diagnosis was later confirmed by a trusted garage who carried out their own test and found exhaust gasses in the coolant. The second test i carried out was on a SEAT which has been suffering from coolant loss for at least a year or so. As I'd already bought the test kit for the Audi i thought I would give it a go with this car too. Again the test came back positive (liquid turned blue to yellow very quickly). This diagnosis was also later confirmed by a garage who found the EGR cooler had failed. I also tested our other vehicles and thankfully in those cases the tests all came back negative. In summary a really useful kit, very easy to use and in my experience 100% accurate.

Worked as expected. Got results in just a min.

Quite good, but it did give me a false reading once.

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!

Ha Cambiato colore e confermato la diagnosi.

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🥳

Würde ich immer wieder kaufen. Schnelle Lieferung, einfache Anwendung und funktioniert auch bei Traktoren.

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.
