What van is it?

its a partner van mate, which i guess is the same as a berlingo aswell.

Phone the dealer and ask for the service department.  Give them the registration (which will be on their database).  Then they'll know the exact model and they'll be able to tell you when the cambelt is due.  Some vehicles it's 40,000, some it's 60,000, some it's 80,000, etc, etc.  Get it wrong and you'll pay heavily.

Or just ask a bloke down the pub.
