Re: Waterpump/belt failure on the JTD 16v engines
Mine went last year at 62,000, 4 year old 16v m-jet 147. The water pump bearings went, the shaft wobbled about and threw the belt.
Most of the rockers snapped, valves and pistons were ok. Alfa Romeo went halves up on the bill after I asked for a goodwill payment as the car was out of warranty but the belt snapped 10k before the scheduled change. Pleasantly surprised by the payment and I'm not really out of pocket because the belt would have had to be done this year anyway.
Good luck getting yours fixed a-team. Could be worth a cheeky letter to AR to see if they'd contribute towards the bill.
