There is SO much 123 information buried in the innards of this forum, searching here probably is at least as good as any manual you can get. Some of the posts are over 20 years old so set the search engine accordingly. In the 2000’s, the 123 diesels were a mainstay of conversation and consultation on this forum. It’s hard to imagine any issue about them was not discussed.

Of course, do your searching the Diesel Discussion sub forum.

I personally drove and maintained 123 diesels over 800,000 miles, and maintained about another couple of hundred thousand for the family.

Your picture looks great. Hopefully the car doesn’t still have the Chrysler Airtemp HVAC system. That was the downside to the earlier version.
