UView 560000 Combustion Leak Detector for Automotive Engines

Jack Bernard: Nothing to dislike about it, it’s easy to use the price is good. And hay it could save you from having to buy a new motor or transmission!

caddisguy: As several others reported, my product had already been opened. The seal on the tester fluid was peeled back part way, but the bottle was still mostly full. This leads me to believe someone used the test fluid and poured it (or water) back in, potentially contaminating the entire test. How can I trust the result? I can't. Get it together guys. If you are going to accept returns on a product with a shelf life and that is sensitive to contaminants (as indicated in the instruction) at least check to see if it was tampered with before selling it to someone else.

Elizabeth MarcotteElizabeth Marcotte: Just received it today and item has previously been used then returned... missing some of the blue fluid. No one must of opened it when it got returned since it was obvious there was missing liquid... disappointed

ODCaveman: Product works great. Very simple to use. Comes in a nice carry case and honestly the best part is it gave me peace of mind and confidence I did not have a blown head gasket issue in just a matter of minutes without having to tear into the engine. Tested it by sucking in my own breath and sure enough the fluid turned color just as expected. I used it on a 6.2 diesel that had some brown foam in the coolant. Turns out it was just nasty coolant and not oil as I originally dreaded!

It is not cheap considering the amount of use the average DIY mechanic will use it but I feel it is well worth the money to know for sure if there is an issue or not. It would also be great for used car shopping! Quick way to evaluate engine health.

Seth Elwyn Burgin: Clever and relatively effective. I could only get it to pull a very slight vacuum in the air space inside the radiator before having to break the seal, and allow some more air into the radiator, but to allow for that I pumped air through it 26 times, and the fluid remained blue. I don't know how well it could work with a thermally induced intermittent type leak, but I am sure they do exist. After the test was negative, just for general purpose take the device back NEAR, but NOT IN, ON OR TOUCHING THE EXHAUST PIPE, and pump some air through it. The liquid will quickly change to a light green tint. Pump some more air in, and with a gasoline engine, the liquid will quickly turn yellow. This device lets me know if I am pissing up a very long expensive rope before I get too far along throwing time and money at problem I may not need to or wish to deal with.

J. Canfield: I bought this to make certain I wasn't fighting a head gasket leak, cracked block or something else while trying to improve the cooling system on my newly supercharged Jeep Rubicon with the I-6 engine. I have tried various radiators and fan setups and settled on a Mishimoto radiator and a Ford RF-39 electric fan as the best combo so far for trail and street. Thank goodness the leak tester detected no exhaust gasses in the coolant, phew.

The product is well made and easy to use and comes with enough fluid to last the backyard mechanic probably a lifetime. The instructions did not mention needing to run the engine or if you could test the air in the expansion tank with a cold engine and cold fluid, I asked a question here so I knew to pull the cap and run the engine until the thermostat opened up and then performed the test.

By the way, the Mishimoto radiator has a smallish non-standard radiator cap and the tester was a perfect fit thanks to the wedge shape on the bottom on the tester.

JFF: Works great. the dual chamber design is nice, but I don't know if it is necessary. It may just use more fluid, but the fluid is inexpensive so no big deal. Comes with a nice durable blow-molded case with a handle just big enough to sit the chambers in while filling. Its portable and could be used to check out a used vehicle's system before you buy.

Tips:
What I found was that I hold the tester onto the neck of the coolant tank and give one of the radiator hoses a gentle squeeze so that more gases pass through the devise.
Another tip, the fluid will often return back to blue when exposed to oxygen again so you can reuse it a few times. I would keep the used fluid in in a separate container though!

I was able to determine that none of my vehicles had headgasket issues, as I first thought. It turns out that one was a water pump seal gone bad and the other a bad heater.

My only concern with the unit is with its longevity. This may be a miss founded concern, but it appears that the rubber may dry our and crack over time.
Just my opinion.
