Repairing a 2001 Dodge Ram 2500 equipped with the 5.9 liter Cummins diesel motor may be simple or difficult, depending on the required repairs. The 5.9 liter, 24-valve Cummins diesel was available in model years 1998 through 2002 before being replaced with a common rail injection system. Many repairs may be completed by a do-it-yourself owner, while others should be performed by a professional mechanic. The first step in repairing your Dodge 2500 is to identify the problem and all affected parts.
Diagnose the issue with the Ram by evaluating the pickup's performance and referring to the manufacturer's auto repair guide. Stalling, slow throttle response or lack of power may indicate an issue with the fuel systems or turbo charger. Trouble shifting could mean a transmission problem. The 2001 Dodge Ram 2500 is also equipped with a data port located underneath of the dash board on the driver's side. Plug a code reader, available at most auto parts stores or through a professional mechanic, into the port and read any codes that may indicate issues with one or more of the truck's operating systems.
Identify the components and parts that operate the affected systems and test their performance. Note any under-performing, or broken, parts for replacement. Check to make sure that routine vehicle maintenance, such as oil change and transmission service intervals, are also up to date.
Remove broken, or malfunctioning parts, and take them to a local auto parts store to match for replacement. Use only parts that are application-specific to the 2001 Dodge Ram 2500, or intended for universal use. Install new parts according to the manufacturer's specifications and perform any neglected routine maintenance.
Test drive the vehicle under variable driving conditions and evaluate whether or not the issue has been solved by the replaced or repaired parts. If not, refer back to the manufacturer's auto repair guide and re-evaluate the source of the Ram 2500's problem.
