Dear Vintage - Opel friends,I'm pleased to be able to offer you the following article:
The original rubber seal ring, which is responsible for sealing between the thermostat housing and the cylinder head, cannot always fulfill its task to a satisfacory level. For this reason, we have created this paper seal as a supplement. After you have installed this seal, you can confidently rule out this sealing surface as the source of trouble when losing coolant :-) Made by edelschmiede!
