I'm just about to replace my thermostat but before attempting this can someone advise whether I require a gasket as I haven't received one. If a gasket is required can I use a liquid gasket.
Yeh instant gasket will do if you don't have one.
Mates 200 boiled when in the middle of nowhere so took the stat out and made a gasket out of beer mats from an odd pub (in the middle of the nowhere place!!). It sealed it a treat!! Drove 300miles home on it and didn't leak a bit!
