When our beloved trucks were new, the engineers at Dodge who designed our trucks, created a how to manual for dealer technicians on how to repair anything that went wrong on our trucks. These books are known as service manuals. These manuals cover every parts of the truck from driveline, to HVAC system, wiring diagrams, to even how to disassemble a door. While a few aftermarket companies like Chiltons have made similar service manuals, none of them covered the same details as the Factory Service Manual.
Many people have been fortunate over the years to get a used dealer manual to help assist the repairs or restoration of their truck. As the years have gone by though, clean copies without missing pages have become harder to find.
That has all changed now withe help of Mopar Authentic Restoration products allowing reprints to be done. These fully licensed manuals are identical reprints to the original manuals and cover the same information, right down to the Chrysler logos.
There was no diesel supplement for 1992. All Cummins diesel information was included in these main two books.
For 1992 TBI trucks however, there was a special manual done for diagnosing the 1992 TBI engines. Be sure to order the supplement if you have a TBI truck you are working on.
