Does the jobs, just do it!
Amazing! I had quite a substantial waterleak on my 3 series Scania. But after trying this, the leak stopped within about 10 seconds of running the engine. One thousand miles later and still not a drop of coolant leaks out, absolutely amazing stuff.Further to this, the vehicle builds up to the correct temperature and stays there. It no longer overheats, like it did previously with the coolant leaks.If you've got a coolant leak, then this is definitely worth a punt.

Brilliant product - Does exactly what it says - leak fixed
I was having sudden major loss of coolant, discovered a leaky expansion tank previously and had already replaced tank, but problem then worsened!Couldn't see any obvious leaks from the radiator, and all hoses were sound, unlikely to be the water pump as the problem would have been worse, so likely a gasket or seal somewhere being the cause of the leak.Added 1 container of K-Seal HD, and within an hour or so of the engine getting up to temperature, the leak was fixed with no further loss of coolant. I have put over 3000 miles on the car since adding K-Seal, and no further loss of coolant.Car is Audi A6 Allroad 3.0 V6 Diesel with c.100,000 miles on the clock.Bought another K-Seal to keep in the boot - just in case!

Its better than nothing...
Seems to work though it take a while to become effective. We had a small leak from the seals on a still-tube radiator and it definitely fixed that, however it did not fix a weeping compression joint.

If it works it works.
Well after £2000 getting a head gasket done on a narrowboat I was told it was the block that had a crack, couldn't afford the price of a new engine,I did my research on the leading brands and purchased k-seal as there have been either glowing reports or failures, well this definitely worked for me.I should have done this in the first place, 20 minutes after the engine heated up it was fixed. 4 months on and going strong.
