This procedure covers the removal and replacement of the power steering pump on a 2014 Ram 2500 with the 6.7L Cummins diesel engine, including serpentine belt removal, pressure and return line disconnection, and fluid refilling.

Warnings

Tools required

Parts

• Power steering pump × 1 — Use OEM specification
• Power steering line O-rings × 2 — Use OEM specification
• Serpentine belt (if worn or damaged) × 1 — Use OEM specification

Fluids

• Mopar ATF+4 — 1 qt

Preparation

1. Ensure engine is cold and vehicle is parked on level ground
2. Disconnect negative battery cable
3. Raise and support front of vehicle on jack stands if additional clearance is needed for access from below
4. Remove engine belly pan if equipped to improve access
5. Place drain pan under power steering pump area
6. Use turkey baster or fluid pump to remove as much power steering fluid as possible from reservoir to minimize spillage

Procedure

1. 1

   Remove serpentine belt
   Locate the serpentine belt tensioner on the front of the engine. Using a breaker bar or serpentine belt tool, rotate the tensioner clockwise to release tension on the belt. Slide the belt off the power steering pump pulley first, then remove it from the remaining pulleys. Inspect belt for wear, cracks, or glazing and replace if necessary. Note the belt routing diagram on the fan shroud or engine compartment for reinstallation.
2. 2

   Disconnect power steering pressure line
   Using a line wrench (flare nut wrench) to prevent rounding, loosen and disconnect the high-pressure line fitting at the pump. This is the metal line with the larger fitting. Position drain pan to catch fluid. Once disconnected, immediately cap or plug the line and pump port to prevent contamination. Remove and discard the O-ring from the fitting.
   ⚠Residual pressure may be present in the system. Fluid may spray when line is first loosened.
3. 3

   Disconnect power steering return line
   Locate the return line connection at the pump (typically a hose with a clamp). Use pliers or a screwdriver to loosen the hose clamp, then slide the clamp back on the hose. Twist and pull the return hose off the pump fitting. Allow fluid to drain into pan. Cap or plug the hose and pump port immediately.
4. 4

   Remove power steering pump mounting bolts
   Locate the power steering pump mounting bolts. On the 6.7L Cummins, there are typically three mounting bolts securing the pump to the bracket. Remove all mounting bolts while supporting the pump. Note the location and length of each bolt as they may be different sizes. Remove the pump from the engine bay, maneuvering it carefully to clear surrounding components.

   Pump Mounting Bolts25 Nm (18 lb-ft)
5. 5

   Transfer pulley to new pump if necessary
   If the new pump does not come with a pulley installed, the pulley from the old pump must be transferred. Use a pulley puller to remove the pulley from the old pump shaft, taking care not to damage the pulley. Press or install the pulley onto the new pump shaft, ensuring it is seated to the same depth as on the original pump. Most replacement pumps come with pulley already installed.
6. 6

   Install new power steering pump
   Position the new power steering pump onto the mounting bracket, aligning the bolt holes. Install all mounting bolts finger-tight first to ensure proper alignment. Once all bolts are started, torque the mounting bolts to specification in a crisscross pattern to ensure even seating of the pump.

7. 7

   Connect power steering pressure line
   Install a new O-ring onto the pressure line fitting, lightly lubricating it with clean ATF+4 fluid. Thread the pressure line fitting into the pump by hand to ensure proper alignment and prevent cross-threading. Once hand-tight, use a line wrench to torque the fitting to specification. Do not over-tighten as this can damage the O-ring seal.
   ⚠Always use a new O-ring when reconnecting pressure line. Reusing old O-rings can cause leaks.

   Pressure Line Fitting30 Nm (22 lb-ft)
8. 8

   Connect power steering return line
   Slide the return hose onto the pump fitting, pushing it on until it seats fully. Position the hose clamp over the connection point and tighten the clamp to specification. Ensure the hose is routed properly without kinks or interference with other components.

   Return Line Clamp4 Nm (3 lb-ft)
9. 9

   Reinstall serpentine belt
   Route the serpentine belt according to the diagram noted during removal. Install the belt on all pulleys except the power steering pump pulley. Rotate the belt tensioner clockwise with a breaker bar or belt tool, and slide the belt onto the power steering pump pulley. Release the tensioner slowly to apply proper tension to the belt. Verify the belt is properly seated in all pulley grooves.
10. 10

    Fill and bleed power steering system
    Fill the power steering reservoir with Mopar ATF+4 to the cold fill line. Start the engine and let it idle. Turn the steering wheel slowly from lock to lock several times (do not hold at full lock). Check fluid level and add as needed. Continue turning the wheel lock to lock until no air bubbles appear in the reservoir and the fluid level stabilizes. Top off fluid to the appropriate level mark. Check all connections for leaks.
    ⚠Do not hold steering wheel at full lock for more than 5 seconds as this can damage the pump.
    ℹ️Fluid level will drop as air is purged from the system. Add fluid as needed during bleeding process.

Reassembly

1. Reinstall engine belly pan if removed
2. Lower vehicle from jack stands if raised
3. Reconnect negative battery cable
4. Clean up any spilled power steering fluid from engine and surrounding areas
5. Dispose of old power steering fluid according to local regulations

Verification

• Start engine and verify no unusual noises from power steering pump
• Turn steering wheel lock to lock while idling and verify smooth operation with no whining or groaning
• Check all line connections for leaks while engine is running
• Verify power steering fluid level is at proper mark on reservoir
• Test drive vehicle and confirm normal power steering assist and no unusual noises
• Recheck fluid level after test drive and top off if necessary
• Inspect underneath vehicle for any fluid leaks after test drive
