1.9 JTDm 16v cambelt - should I use a specialst?

Ok, I know if I had a petrol Alfa, I would definitely go to an Alfa indie for a cambelt change. But, seeing as the JTD is used by Saab, Vauxhall and Fiat, is there really any need to use a specialist? I mean you don't see Saab or Vauxhall drivers with the same engine using independent Saab/Vauxhall specialists - I've never heard of any for starters; these poeple use any old garage (if they don't use the dealer that is). I know I could get the job done much cheaper by using a good local 'general' garage that I have used with other motors in the past. What are peoples' opinons on this?

I don't read the script, the script reads me

The Italian Group JTD engines, as licensed to GM, may have the same blocks, but I think you'll find that the heads of these engines (and more particularly the cam profiles) would be different from say, an Alfa JTDm, and the same block found in a Vauxhall.

Following on from this I would presume that the cams would need to be locked when changing the belt? You certainly need to do this on the petrols, but on the diesels this may also be necessary - in which case the garage would need the correct cam locking tools to do the job properly.

Personally, I would take it to a good Alfa specialist who is familiar with these engines. I wouldn't take it to a 'general' garage round the corner. The specialist may be a little bit more expensive, but hopefully they'll do the job properly. There is nothing worse than a cambelt job being botched - you'll regret it bitterly if this ever happens to your 147.

Finally, when you get the cambelt/tensioner/idler done, change the waterpump as well. Take a look at the sticky thread on 'JTD waterpump/cambelt failure' on here if you need to know why. Again this is more of a reason to use a specialist, as most will change the pump without additional labour - something a 'general garage' will be very unlikely to do.

Check that the garage has the proper Alfa cam locks (if they don't know what they are then never take your car to that garage ever again) ... personally I always take mine to an Alfa specialist, they are actually usually cheaper in the long run because they "know" the cars and as such will do work quicker ...
