Coolant Pipes Epoxy Fix

The coolant pipes are not as expensive as the water rails, but it's still £400 to replace them

The originals appear to have a manufacturing fault the reveals itself as a weak seam that eventually fails

I used epoxy resin to flow in to the pipes to seal them, and so far it's worked well

I did a similar repair about ten years ago to fix a hole and it's not leaked since so I'm optimistic that the new fix will work as well

That was certainly a prescient warning

Yesterday I parked up in the corner of Dunkirk Carrefour car park, in order to swap out the thermostat with a used spare that I carry with me

The thermostat had stuck partially open, meaning I was cold and miserable, and the fuel consumption on the way to Dover was so bad that 140 miles cost €90

Epoxy is supposed to be stable in water, and good for up to 120C continuous

However, when I took the thermostat out, although there was no debris at all, there were signs that it was gummed up

It wasn't difficult to free it up, but I fitted the spare anyway

So my advice is - Don't be cheap like me, you might end up regretting it

The car has just survived a track day without any thermostat issues (or any other issues for that matter)

I will keep updating this thread, as I'm still not ready to sink £400 on a set of new pipes
