K-Seal

Stuff works great!! – Was sceptical after reading some negative reviews but gave it a go as changing my water pump on my volvo c30 turned out to be a pain! After buying the pump pulling stuff apart I failed nearly ringing the mechanic to sort it. With limited funds and knowing it would cost an arm and a leg..K-seal went in my overflow tank ran it for a while and from… Read more

what was a big coolant leak STOPPED!! I couldn’t believe it! Next morning checked my overflow and it was down and thought it was too good to be true, so topped it up hoping for the best and the best it was..not one drip anywhere. YES! Great product hopefully it holds up. I recommend this product it actually works:)

K-Seal. Coolant stop-leak that works! – Owning a 2003 Rover Connoisseur (2.5 V6), I have been plagued with what appears to be a common problem with this model ... adding even the smallest amount of stop-leak to the cooling system will block the heater matrix! Believe me, I've tried them all - from stop-leak with rubber bits to stop-leak with aluminium filings to all impressive (not)… Read more

magic potions that promise the world but fail on delivery. Topping up the radiator became a regular annoying occurrence. Believing there had to be a solution to this problem, and not wishing to strip down the engine to fix a small water leak which appeared to be coming from the inlet manifold (another known issue on this model) I tried one more time to search the internet for the solution.

By chance I came across K-Seal ... available in most car accessory shops. The reviews appeared good, but I'd come across similar before. Reviews can't always be believed. I contacted Colin at K-Seal UK and asked his advice. Not really expecting a reply (been there, done that), I was surprised to receive a very prompt response explaining, in detail, how I might overcome the problem. Wow! 10/10 for customer service. Following his advise, and to my amazement, the leak was fixed almost instantly. Furthermore, the heater was still working perfectly. There had to be a catch, right? So I left it for a few days ... then a few days more ... then I took a long trip into the country ,,, but, despite my efforts, I was unable to disprove K-Seal's promises. This product really did work!

K-Seal is an amazing product and I have no hesitation in recommending it. If you have tried other stop-leaks which have failed, don't let that influence your decision with K-Seal. I don't know what the magic potion is, but it works ... brilliantly. Colin and the team at K-Seal have in-depth knowledge of their product and, from my experience, are more than willing to help with advice - something not often seen these days.
