Are FirstGeneration Dodge Cummins Reliable?  

broken image

When you decide to buy Dodge Cummins, one of the factors that you should take into consideration is reliability. The first generations Cummins are very reliable, so you should definitely consider them. The first Cummins Ram was launched in the year 1989 as an option on 250 and 350 series pickups. Even though the headline power figure for the Cummins was not impressive (at only 160 hp), but the important figure was the torque, which at 400 lb.-ft. was far more than any gas motor available in a Ram at this time. 

Better yet, compared with gas motors, the diesel offered significantly improved fuel mileage. These Cummins had both a turbo and direct injection, unlike the contemporary Ford and Chevy trucks which did not. This means that the engine of these Cummins did not need glow plugs, and thus was more reliable. Available transmissions were the venerable Mopar 727 automatic and a five-speed manual.

This era of Ram suffered from a dated design because the basic design of the cab had entered production in the year 1972. The interior had received a number of updates since its introduction in 1980, even though ABS anti-lock brakes became standard on Rams in the year 1989. The grille was redesigned for 1991, but retained the rectangular headlamps and crossbar grille. 

In 1984, the Cummins B-Series engine had entered production, first in Rocky Mount, North Carolina, and then in Mexico, Turkey, and England. The bores of the B-series are machined directly into the block. Instead of using wet liners, they use a one-piece cylinder head. Commonly referred to as the 12-valve to differentiate it from the later 24-valve, the name refers to the design of the cylinder head - 12-valve trucks have the traditional one inlet valve and one exhaust valve while the 24 valve motors have two inlet and two exhaust valves.
