After one week in the dealer the alternator and belt are not available in any dealer, warehouse or distribution center in the United States, Mexico, or Canada. I have a tentative date of 12/29/2015 for the alternator but still no eta for the belt. Call Dodge Corporate Customer Service and was told that they did not or could not answer why these parts are on back order and not available in the north american continent. But they did forward my parts order to a department that may be able to get the parts faster. Has any one ever had any hot alternator problems on the eco diesel engines? The reason I ask is I think that there may be a large failure rate and the factory can not get replacement parts fast enough. So if anyone has had a alternator and belt replaced it would be of interest to know the number of replacements done. The only other reason could be a lack of production an they can not make the parts fast enough for new trucks for sale. So if you have a Promaster diesel and have had a alternator problem please post.
