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.
For 1991, Dodge added the diesel content into the main books. There was however a 3rd book done for 1991 covering the 1991.5 intercooled engines. This was known as the 1991 diesel supplement. It is not included with these two manuals, but can be added to the order so you get all three books. It is not needed if your truck is a 1991 non intercooled however.
There was also a 1991 TBI supplement for gas trucks. This book walked you through the diagnostics and repairs of a throttle body injection truck. These are a must for anyone trying to repair one of these early TBI trucks!
These manuals cover 2wd and 4wd trucks from Ramcharger, 150s, 250s, and 350s.
