    Easy to use

    Was losing coolant on my Audi (2002). Not worth replacing head gaskets so garage suggested I try this. Very easy to use and over a month later no coolant lost and car running well. Don't expect it to last forever buy definitely great value!

    Didn't work

    I bought a cheap runaround for a few months which turned out to have a cracked head and was pouring out white smoke from the exhaust. Wasn't prepared to pay the huge garage bill on a cheap car so put this through which helped but hasnt fixed the problem. Might get a couple more months out of the car which is fine as that's all it's needed for, but for a good car that you plan on having awhile pay to have it repaired properly

    Short term fix?

    I used this product on an old banger and it has stopped all evidence of water leaks into the engine. However the car is used for short journeys and is never driven hard so the jury is out on whether it would cope under those circumstances. I would always recommend that the head gasket is replaced but I looked on this as a short term measure which appears reasonably successful. Not particularly cheap though.

    works to get you out of trouble

    it stopped the head gasket from blowing oil out of seal between block and head for 3 days but now back to my 1st problem i.e no3 stops firing, so maybe i have a different problem, so as i cant confirm the reliability of the product 100% i will give it 3 stars

    Just the Ticket

    I'd been having some trouble with losing coolant from my late 2008 Ford Fiesta and a search online pointed me in the direction of a possible head gasket issue. With a bit of research I'd stumbled upon K-Seal. It is incredibly easy to use, with a simple good shake and emptying the contents into the coolant tank before running the engine with the fans turned up on cold. It seems to have helped massively; there is still a leak but it's much better than it was and my engine seems to have a bit more oomph now too, which cannot be no coincidence. Recommend trying this product if you have similar issues.
