If any of these block other parts of the system then it was partially blocked already, independant testing have shown that K seal will not block anything bigger than 0.8mm which is far smaller than any waterway in any vehicle, if you had issues it's nothing to do with the product but the incompetence of the person doing it...

Follow the instructions and help from the manufacturers and they work as stated...  Pete

any other thoughts have been quoted 1400 as a start

tbh pete I thought you was a good guy and had knowledge not a cowboy oh well you live and learn good luck to the op

harlen search k seal and read uk marines post to see what the k seal did to his purchase then make your mind up its not a cure if its broke fix it properly cheaper in the long term

I don't waste money though, they state it is a permanent fix, Rolls Royce supply every new car with a leak additive in the cooling system in case a small leak develops and creates a breakdown. If it's good enough for them........ I don't consider it a bodge if it cures the problem, you wouldn't replace the whole engine for a bent valve, why change and entire gasket for what will be a very small leak, if you can repair then why replace....

The worst that happens is that you have to do the job you were going to do anyway...!!! Pete

sorry i thought it did do you know the difference between them

Rawhide pete I'm a gas registered fitter and if a tenant or customer has put a leak seal in an boiler 99% of times it doesn't fix the problem 2 it invalidateds the warrenty if the system has had it in and would you buy a car if you knew it had k seal init ?? I doubt very much I'm sorry but your advise stink FIX THE PROBLEM SORTED

ps I thought the site was to help people not give them a bigger problem

Hopefully i will be the 1%

And I thought the site was a grown up place, not a 'playground name-calling' one.
Not everyone agrees on here but IMHO Pete has been a great help to many.
