Recently my car seems to have developped the dreaded coolant seal leak. I want to try and get it fixed with the well known coolant seal fix. Problem is I live in Belgium (Europe) and can not find CRC block weld over here. Does anybody know of similar products or ingredients that should be in there???

 

I had good luck with "Barrs-leak" (the brown powder type)
I seems the copper or metallic based ones do better than the organic types in our engines.
The main trick is to put part of it in & do a full hot to cold heat cycle, then repeat.

It held for months in my old NA (before the black turbo seduced me).

 

I didn't do this because I wanted to give usable housings to my friend.

It will prevent the rebuilding of the engine later on.
