I love my 2002 2.5L CRD which has a lot of parts that the 2.8L CRD has.
However getting spares for either model is very difficult...the Mopar Agents usually have to order them...I have usually had to give the Agents various part numbers that they need to look for....the Timing Belt for instance!
The Agents had one part number only for the belt and they could not find it...I gave them two further numbers and that helped them.
The Idler Pulleys for the Fan Belt they could not obtain for me...they had the Fan Belt and the Belt Tensioner but the only option was for me to try get to Idler Pulleys from USA Part suppliers... but nobody ships to South Africa!
So I had to take my Idler Pulleys apart...one had totally seized...and fit new Ball Bearings to them!
So unless you are prepared to shop around or visit Breaker Yards I would suggest that buying any KJ is not a wise move!
