300 Tdi Overheating with a difference ?

Hi Dave, I'm not a fan of using silicon on cooling systems as 'overflow' silicon squeezed out on assembly invariably settles in the core and can decrease flow/cooling. :(

The replacement metal P gaskets are quite good. I've stuck mine in with soft set aviation cement.

Deano :)

Don't put it on too thick and then let it dry. Being doing it for years on water pumps, thermostat housings etc and never had a problem.

Each to their own though.
