While the manual covers all engines, the Dodge Ram 4000 DX Series in this era was commonly equipped with the 5.9L Cummins 24-valve turbodiesel engine. Gasoline V8 options were also available. Specific engine codes and variations will be detailed within the manual.

Performance Notes:

The 5.9L Cummins 24V turbodiesel typically produced between 235-305 horsepower and 460-555 lb-ft of torque depending on the specific year and configuration. Gasoline V8 engines offered competitive power for their class. The manual will provide exact performance figures for each variant.

Fuel System Diesel:

High-pressure common rail injection (for later Cummins models) or direct injection systems. The manual will detail fuel pump operation, injector service, and fuel filter replacement.

Fuel System Gasoline:

Multi-point fuel injection (MPI) systems.

Cooling System Details:

Pressurized coolant system with thermostatically controlled fan. Manual covers radiator, water pump, thermostat, hoses, and coolant specifications.

Lubrication System Details:

Pressurized oil system with oil pump and filter. Manual specifies oil types, capacities, and filter part numbers.

🔧 Transmission

Transmission Options Diesel:

Commonly paired with the NV5600 6-speed manual transmission or the NV4500 5-speed manual transmission. The 48RE 4-speed automatic transmission was also a popular option, especially with the Cummins engine.

Transmission Options Gasoline:

Automatic transmissions like the 46RE and 47RE were standard or optional with gasoline V8 engines.
