Uview 560000 Combustion Leak Tester

Good product excellent

💯

This thing works. The bad news is, that it can bring bad news. It is somewhat difficult to assuredly determine if a head gasket is compromised, but this device, when used correctly, is very hard to fool. It looks for carbon dioxide in the head space of the radiator and, if detected, reveals that combustion gases are getting into the coolant. You are instructed in the pamphlet how to prepare the head space of anything but coolant vapor, and this is the only challenging part of the test, but not too difficult to do. Done properly, there is no way to get a false positive. Also, you can "test" the indicating solution by exhausting some of your own breath and observing whether or not the fluid in the apparatus tube changes color. Unlike other devices I considered, the tube has two places where the headspace vapor is tested for CO2, and the certainty of the result is appreciated. The device is well constructed and exceeded my expectation for the quality of the components, the ease of use and even the nice box to store it. It is thick enough to last and the rubber gaskets are tough. Anyway, the test did indicate a blown head gasket on my 4runner and that means it's crying time for me. This test was the last in a few steps of diagnosing and while I do not like the news, I trust the source. Excellent device and suitable for a commercial shop and any do it yourself-er.

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

Not really sure why i needed to purchase this product as i think my dealership should have a tool like this but of coarse it's not around when we need the tool. So decided to purchase the tool myself for my own use and what i can say this is a lucky tool to have around. I had a 2015 Chevrolet Silverado 2500 with a 6.6L that i suspected to be a head gasket because they are common for the right side to break so i wanted to fully determine that it was indeed a head gasket failure without guessing. The tool came early and used it the next day. The setup for the tool is simple as pouring in the blue fluid and starting the engine. Not even 30 seconds and the color changed from blue to green, then started bubbling over the tool because of the amount of combustion pressure. The tool worked flawlessly and results were accurate. I was lucky enough to dissemble the job and found the right side gasket broken. Why they do that,? I have no idea. The following week, used the tool on a Cruze and quickly determined head gasket failure. The tool is a must have for any mechanic and ensures a correct diagnosis is made the first time. Tool is pricey but i think worth the money to ensure yours or a customers vehicle is diagnosed correctly. Would totally recommend.

Worked well. Liquid is reusable if it shows a negative. Nice case,plenty of reusable liquid. Good instructions,easy to use.
