I posted at the end of June about the troubles I had with getting an air con belt for my 2008 2.3l Ducato. I ended up reporting that all was well and it had been fitted. However that was not the end of the matter. I went away soon after it was fitted and every time I tried to use the aircon there was a terrible screeching. Especially bad on low revs. It certainly got everybody's attention when we drove through Skegness on a warm day! Obviously the belt had not been tensioned properly and was slipping whenever it came under load. Phoned garage and arranged to take it in when I was back home. So just back from my visit to the garage. They were very apologetic. They say that the belt Fiat have listed in their parts catalogue and provided to them is slightly too long and they are unable to tighten it. They say their parts department are trying to sort this out now with Fiat and will phone me when they know. If that really is the case I would suspect that some other people on this forum would have had the same problem. Anybody had the AC belt on a 2007+ (new shape) 2.3l Ducato replaced and if so did you have this problem or not please?
