These days car manufacturer's quality is in the can. What a pun! Who tests for MTBF? No one! If they do it's mostly simulated, or done with algos.Along comes Bar's Leak for Head Gasket fix. A novel way to solve such expensive issues more cheaply.If you have changed the water pump (leaking) 3x on a German car made in Hungary, now in Mexico without success try this!The product bottle can be improved. Make a section of it viewable, so you can see how much of the bottle you have used, like with a Mobil 1 Quart of oil container.Updated October 10, 2022.So far the coolant tank has congealed bar's leak product in it. Hopefully this is not impacting the ability to efficiently cool a hot engine. The thermostat indicator suggests not. I used half a bottle, based on engine size (4 cylinders). See photo.Rated 4, as the bottle and labels can be improved.

Had a tiny leak in the head gasket. Did not do anything for the first try, however stopped the symptoms once repeated. Does not have enough for multiple times on big engines. Might wanna order the big size. Make sure to completely heat up and completely cool down engine and not take it to the interstate for first test drive.

It's been about one month since I applied the treatment to my 1980 yanmar tractor. The tractors engine block had a significant crack in it that had been brazed together. The treatment has reduced leaking from block. So far it's working as expected!

I have a 2016 malibu with a 1.5 turbo with 91000 miles. I was getting antifreeze vapor out the tailpipe upon startup. Obvious head gasket leak although not a bad one as I have only lost half a gallon of antifreeze over the last five months. used the bars fix product and it worked. 1500 miles later and still no gasket leak. Will see how it does longer term.
