The head gasket could be blown without loosing water. depends on where the head gasket is blown. Could be just loosing oil out the side of the engine. could have oil leaking into cylinder head, or it could be leaking oil in the water, or water into the oil. This video only works if the coolant is leaking into cylinder head. The best way to check it is to do a compression check on the engine.
Do you do the test on a cold or hot engine? I thought the test was conducted on a at operating temperature engine, but if thats the case, wouldn't coolant rise to the fill neck of the radiator/overflow tank rendering the results useless?
@@spencerleeb the engine can be hot or cold. If the head gasket is blown you will get the combustion gasses in the coolant any time. It is safer to do it on a cold engine to reduce risk of getting sprayed with hot coolant.
It is possible for a blown head gasket to cause the engine not to start. When the head gaskets blows it will let coolant leak into the cylinders and cause "hydro lock" which it would impossible to start. So the mechanic may not be lieing.
Take the spark plugs out and rotate the engine if there is coolant in the cylinders will shoot out and you will know that's what's causing it to not be able to start

it is amazing how that works. i am a diesel mechanic and we use the same method. works every time. very informative video.

I've seen this used on a2017 Escape with the 1.5 eco boost. It works.

I bought a similar product but it doesnt have the pump with check valve. I wonder if it works the same
Amazing videos❤❤❤
Do you do this with coolant in the radiator or an empty radiator? Mine is currently empty
You can just add water to do the test. That way you don’t waste money on coolant. But you don’t want to run it without coolant.
How would this work if my radiator is sealed? Can it be used on the reservoir?
Yes, you use this wherever you add fluid.
Does this work if the car doesn't start? My mechanic says my car won't start because my head gasket is blown- I don't believe him
It is tough to get this to work if the vehicle won’t start since the combustion gasses from the engine running is what this detects.

If there is no water in the reservoir before I perform the test won't that guarantee damage?
It could be low due to a multitude of issues.
@@YourCarGuyDR I hope you're right!! I'm not going to test it myself with the kit! I'm having it towed to a mechanic next month
