I'm wanting to fix a leak in the heater matrix of my Volvo 740. I've read about K seal - which actually claims to effect a lifetime fix. There are lots of glowing testimonials on the maker's site but am wondering if anyone in here has tried it and with what results...

Yes,my coolant level was always dropping very slightly,I suspected a weep in the heater.Put a bottle of K-Seal in and the level has stayed put,plus the nasty smell emanating from the heater has gone.I do not know how it is with larger leaks but it is certainly better than Radweld,which I have never rated anyway.I found some K on ebay at half the price of factors.

Its the best stuff on the market.Nothing else comes close.Best £9 I ever spent,once on a Vectra, once on my wifes Micra. Good Luck !
