Many thanks for the recent help with the items required for a service of my new (to me) Astra. I have the 1998 1.7 TD with the GM engine. The next job for me after pay day is to get the cam belt done. Car has done 136000 miles and last recorded belt change was at 66000. Might have been done since but i have no proof so I want it done. Mechanic I know will fit it for me but I need to source the belt and pulleys. According to him it is as well for an extra £20 or so to get the waterpump done while its stripped. Can any of you knowledgable people give me the part numbers of the bits I need as I have been trawling the web and ebay and there seem to be several variants? Many thanks in advance, I hope over the coing months to accrue some knowledge so I can repay the kind people on this forum.
