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

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.

We used this test kit to find out if exhaust gas was present in the cooling system af a diesel engine. It was simple to use and gave us an answer that prevented us needing to strip the engine.

Excellent product. Was convinced I had a failed head gasket and being quoted a massive amount to fix it. As a sanity check, I bought and tried this. No yellow colour. I took the car to another dealer, who confirmed the car had two faults, neither of which were the head gasket. So this worked for me and gave me the reassurance to question the first garage diagnosis.

Used this to diagnose a head gasket failure on a Honda goldwing. Very easy to use.

Works fine

Great kit I thought it was for one test but you get 20 test well worth the money

I don't wanna say it doesn't work at all but it didn't work for me, but I can see reviews on YouTube where it has worked for people. Doesn't fit snug it seems for me meaning it doesn't stay confained, so may need an adapter?

I had been chasing an overheating issue that was also causing my coolant resevoir to backup. After changing the thermostat which was faulty the isue still persisted. The pressure building in the coolant reservoir was caused by a faulty head gasket. This kit quickly identified the presence of exhaust gasss in the cooling system and I'm now able to carry out a head gasket repair. Very quick and simple to use
