HI all, about to take my first step from Caterham #1 to #2...stepping up to a K-Series R400. Want to refresh Cambelt + tensioner, water pump (while I'm in there) , DS belt and I also hear DS pump should be 'refreshed'... have changed my SS1.6 Cambelt etc a few times..so not worried about process... anyone know the right part number for the belts, tensioner (will it be manual?) also the DS is new to me..so advice on where to get parts/serviced pump appreciated... any other key thoughts ? thanks all Graham
