Not sure why but typically this stuff turns green sitting on the shelf. So far this batch is holding up.

Over the years of using a block tester, I never thought there could be a difference in quality of the fluid being used.Make no mistake this fluid is the fast responding to combusting gasses. When compared to the competition out there this fluid out performs in every aspect.Good quality, easy to use, easy to store and it doesn’t leak.

This kit is super easy to use and I prefer this style as I already have a hand vacuum. I use the same one as for brake bleeding. This as opposed to the other kits that have a built in bulb but that's a spot where it can break and render the kit useless.Its super easy instructions to follow and can give you a look to see if exhaust gases are present or not in the coolant knowimg if there is head gasket integrity issues.

Pues ni modo, me salió cambio de color de azul a verde, quizá la fuga no es grande y por eso no lo cambió a amarillo.Anteriormente, por falla de la bomba de agua hubo sobrecalentamiento, todo el anticongelante se fue al aceite y produjo fuga de aceite en las juntas de las tapas del motor por sobrepresión del vapor de agua en el aceite caliente. Hice cambio de bomba de agua y juntas de tapas (no de la cabeza). Para rellenar anticongelante hice vacío pero no lo sostuvo, pero aun asi lo rellene.Pocos meses despues tuve fuga de anticongelante en el radiador. Lo cambié y aplique vacío para rellenar antocongelante, el vacío se sostuvo pero en un nivel inferior porque cuando lo habia hecho antes del sobrecalentamiento si hacía un buen vacío, pensé que la bomba de vacío ya no tenia fuerza o que alguna junta tenia una fuga no visible.Ahora con esta prueba de cambio de color veo que si tengo una pequeña fuga quizá debida por el sobrecalentamiento y que no me deja hacer un vacío superior, aunque tampoco pierdo mucho refrigerante porque llevo meses con un nivel de refrigerante que casi no baja y tampoco tengo humo blanco en el escape.Ahora a buscar un sellador de junta de cabeza para que aguante hasta el próximo cambio de bomba de agua, porque la bomba esta dentro de mi motor y así aprovecho dos pájaros de un tiro.

Worked as it should.But I didn't know I needed a vacum pump to make this work before I purchased it.Luckily I had one.Would have Given 5 stars if that info was listed.

For a gasoline engine cooling system. May work with diesel, but I doubt it, since I believe that diesels put out less hydrocarbons. I think this company makes a diesel version of this kit. Make sure the cooling system is full, install this glass globe on the radiator opening/surge tank opening, fill with the magic mystery fluid, and connect it to a vacuum source. (Either to engine vacuum, or use a mity-vac style vacuum gun.) If there is a crack around the combustion cylinder, or a faulty head gasket, then you should see the magic mystery fluid change colour. This is just another quick way to check for combustion leaks. Other methods may be performing a cooling system pressure test, and checking for coolant on top of the pistons. Or, install a pressure test gauge on the cooling system, keep it at zero PSI, and run the engine. A bad head gasket may push pressure into the cooling system, and make the pressure gauge needle jump up. Or, perform a cylinder compression test.

Glad I found this on Amazon. I haven't opened the bottle yet, but if it works as good as the stuff that came with my combustion leak kit (which I expect it will, since the bottles are identical), it will work like a charm and at half the price of ordering a replacement from the catalog. Make sure to test your results. That is, if a combustion leak ISN'T present judging by the lack of color change, exhale into the tube and see if the CO2 in your breath is enough to cause the blue to turn greenish-yellow. If not, then the chemical itself is faulty. The process I use is to let the car idle for about 5-10 minutes with the hood open, then get in and raise the RPMs to about 1200-1500 while in Park or in Neutral with the parking brake engaged. Then, I get out, open up the expansion tank cap, and a vacuum line to the engine, and use the vacuum to draw whatever gas is present in the expansion tank into my testing kit tube. I let it do that for about 2 minutes - if the color doesn't change, you're good to go.

Haven't had a positive test on it yet but I'm sure it'll work. The instructions are written incorrectly as it describes using either a red or silver fitting connecting the hose to the tool but there is no red fitting. The one with 2 small holes in the side was apparently meant to be red as that's the correct one to use with engine vacuum and the other without the side holes is for a hand pump. When I used the appropriate engine vacuum fitting, it wouldn't pull air through it at all. I tried taping off one of the 2 holes as someone from lisle suggested but it still wasn't enough so I went with the hand pump fitting and it works but not well as it pulls air through so fast that it just looks like suds. I'll probably modify the engine vacuum fitting to make the holes a little smaller to try and make it work like I'd expect.All in all it'll probably get the job done but if you plan on running into blown head gaskets often enough, I'd go for the more expensive one that has a bulb built into it

Used this to confirm what was pretty certain, a head gasket leak. Sure takes the guesswork and time out of detecting head gasket leaks. I was already 95% certain one or both head gaskets were leaking using cylinder compression and leakdown tests and radiator pressure test. I like the ability to shutdown a cylinder bank and test for a leaking head gasket on one head or the other. Caution, if you do this, you will most certainly trip computer codes and the engine service light on the dash. You need to be aware that you have to check that your code reader (if you have one) will reset the engine service light. Not all will. Many will clear codes but not reset engine service light so you may have to got to a shop to have light reset. Some car models can be manually reset or there is some trick to reset.One of the other anecdotal aspects of this test is that you can tell which cylinder bank is leaking faster or slower. The color change for my testing was gradual, ie it went from blue to green to yellow. This shows that the color change is relatively proportional to the amount and rate of leakage. The color change for the right bank was pretty quick and the color change for the left bank took several minutes. I ran this several times on both a hot and cold engine. The results were generally reproducible.
