K-Seal ULTIMATE will repair most leaks in the head, head gasket and block and has a very high success rate. 1 claim permitted per vehicle. The ceramic micro-fibres in the formula are carefully produced so that they will seal leaks up to 0.635mm in size (but most coolant leaks are in fact much smaller than this).

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.

UNBELIEVABLE HOW IT REPAIRS
My car had had a coolant leak for two month which it was getting worse and worse. The mechanic told me it was a damage head gasket because my Corsa C has got 255,000 km and 15 years old, the oil and water mixed. The mechanic tried with another head gasket sealer but it didn't work even the engine light has been permanent lighting for two weeks. I tried K-Seal, my car was improving every day, the engine light turned off 4 days later, sometimes it turned on. The engine light turned off permanently 8 days after I'd added the sealer in the coolant. My car works good again without any coolant leak.

Suspected head gasket leak
This item did not work. Followed instructions on the bottle. After 2-3 heat cycles the product frothed up through the cooling system and exited out of the expansion tank. radiator hoses still pressurised.

Ultimate K-Seal permanent head gasket repair is easy to use and works in minutes.
Ultimate K-Seal cured a leak on my Morris 1000 cylinder head gasket in minutes. I had used other leak sealers in the past, but K-Seal outperformed them all.

Does what it says
My head gasket had been leaking for a while & I did not face up to it. I found a bottle of normal K-seal in my tool box so I happily poured that into my coolant. Unfortunately this did not stop the leak. So I purchased this Ultimate bottle of K-seal & this stopped the leak on the first heat cycle as described on the bottle. Have been running the car 2 weeks now & still no issues. Very pleased with product, will use again & do recommend.
