Hi - Firstly, excuse any slips from me if I don't follow netiquette - I'm new to this. I've just bought an 2001 Astra Estate Club DTI with 93k on the clock. It runs really well but I have a gap in its service history from 70k-to-date. I can see that the timing belt has not been changed up until the 70k service, and following advice from another owner of an identical car, wanted to play safe and get it replaced. My employer offers competitively priced vehicle repairs and so I e-mailed the garage giving them reg and car details. The garage insists that they cannot tell which engine is in the car from the details sent (reg, chassis no, variant, version), and therefore cannot quote me a price until they know which parts they need. I'm pretty sure that it is an Isuzu engiine, but maybe somebody on the group can clear this up for me? The car was first registered 30 07 2001. Any help would be really appreciated. Seej
