steel seal bottle
Anyone who’s ever had a knackered headgasket, warped head, or a cracked block will know that getting a repair is a labour-intensive, costly business. Well, that’s exactly where the multi-award winning Steel Seal comes in. 
Designed to use a thermochemical bonding process to seal up these leaks, the only effort involved is dumping a bottle in your cooling system and letting it go to work.

It’s a permanent repair too and, if it doesn’t do the job for you, they’ll even give you your money back – you just can’t lose with this one. We almost want a busted head gasket to just try it out. Well almost…

Price £40
