PUD237 you're right it's a bit hard to say isn't it. I was just reading the open thread on JTD cam belts and water pumps and I'm getting a little nervous now. My brain in saying play safe but my wallet is saying how much?
How much I should be looking to pay for a 4 yr service with cam belt / water pump change via an Independent? Presumably it's cheaper to get everything done at the same time?
The whole Alfa servicing schedule is wrong anyway, I don't know how they didn't spot it before it was published. As they say 5 years or 72k for the cambelt which ever comes first, but with 12,000 mile service intervals, surely the cambelt change should be done as part of the 60,000mile/5-year service anyway?
The official 72k/6-year service includes the cambelt & tensioner (but not the waterpump), and it also includes a lot of other stuff as well, which isn't included in the 60k service. (Service Schedule)
On that basis, I would be tempted to ask for a 72,000 mile service as per Alfa Romeo's schedule, but also to change the waterpump as well, which is £37.22 + VAT for the part alone on Shop4Parts. Then you get fresh coolant as well, which is always good for this time of year. If you do this around the cars 4th birthday, I would suggest that is playing it safe. As for mileage, probably 40k on the 16v & 20v is safe. You could do the cambelt every year to be on the safe side, but then that just gets silly, and before long you would have spent more than a rebuild costs anyway.
At 156Chris - I did my old 2.4 10v JTD at 4 years & 55k since the car's previous belt change. Old cambelt looked OK but had a few cracks in it. Aux belt was well and truly worn out, I think it was the original, as the service schedule suggests only to replace the aux belt if it is worn at the point of changing the cam belt.
