UVIEW 560000 Combustion Leak Tester

Arrived on time, and in good shape. Working as described. No blowen head gaskets for me!

Good product excellent

I LOVE THIS TESTER! It is almost worth it just to use it as a science experiment. The tool is so easy to use, basic instructions are all you need. As instructed you can take it apart into 3 parts (the suction part at top, the middle tube, and the bottom tube). You then fill each of the tubes to a fill line easily visible with the fluid. You put it back together and then use either with your radiator (following directions) with the cap off or in my case I used on my overflow for my coolant since my radiator does not have a cap area. You squeeze the bulb at the top around 3-4 times and it brings up air through the bottom tube up into the top tube. If any CO2 is present it will discolor the top tube from blue to a yellow color. My car did not discolor it which is a good thing as it means CO2 from the combustion system was not mixing into the coolant from a blown head gasket or cracked engine block etc. Just to test it I also exhaled my own air into my hand (containing CO2) and sucked that at the same time with the bulb head into the tool and it did start to discolor the liquid to yellow from blue so it works. Very easy to use tool to check if you have a cracked engine block or blown head gasket with CO2 from the engine exhaust going into your coolant. I highly recommend for peace of mind or to tell you what the true issue is to rule out one of these situations if you are worried about it. Plus it is a teachable moment for kids to instruct them on what it does as it is like a science experiment!

El liquido que usa es Azul de bromotimol que es un indicador de PH, por lo cual al combinase con el CO2 forma acido carbonico y el color se vuelve amarillo si hay mucha concetracion de CO2, en mi caso el color fue un poco verdoso pero es probable que se haya contaminado.Importante no destapar el deposito de refrigerante una vez que se introduce el tester
