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

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!

It was very easy to set up and use. It saves a lot of time, effort and costs. It would take you time to book in to see a mechanic, effort and time to get to said mechanic and then the added cost of his time and expertise. This simple but effective product saves all of this. The a only thing I didn't like were the instructions were really in a small font which made the extremely difficult to read without magnification. Apart from that small inconvenience, i would highly recommend this.

Item worked perfectly saved a lot of time and results easily understood well worth the price as it can be used up to 50 tests would cost a great deal more I f going to a garage

Good quality , works as described, helped save hundreds of pounds in repairs.

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.

Cheap sniffer test kit for hydrocarbon nox testing.Effective and accurate

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

great item and easy to use
