This procedure covers the removal and replacement of the engine cooling fan motor on a 2014 Ram 2500 with 6.7L Cummins diesel engine.

Warnings

Tools required

Parts

• Cooling fan motor assembly × 1 — Use OEM specification
• Fan shroud gasket or seal (if equipped) × 1 — Inspect and replace if damaged

Fluids

• Mopar OAT Coolant (Purple) — 2 qt

Preparation

1. Park vehicle on level surface and set parking brake
2. Allow engine to cool completely (minimum 2 hours)
3. Disconnect negative battery cable and wait 2 minutes for system discharge
4. Remove engine cover if equipped
5. Place drain pan under radiator drain plug
6. Open radiator cap slowly to relieve any residual pressure

Procedure

1. 1

   Drain coolant from radiator
   Open the radiator petcock or remove the lower radiator hose to drain approximately 2 quarts of coolant into the drain pan. This provides clearance for fan shroud removal without coolant spillage. Close petcock or reinstall hose clamp when drained.
2. 2

   Remove upper radiator hose and air intake components
   Loosen and remove upper radiator hose clamps at both radiator and thermostat housing connections. Remove hose and set aside. Remove air intake tube between air filter housing and turbocharger inlet to provide access to fan shroud.

   Hose Clamps5 Nm (4 lb-ft)
3. 3

   Disconnect fan motor electrical connector
   Locate the cooling fan motor electrical connector on the fan shroud assembly. Press the release tab and carefully disconnect the connector. Note the routing of the wiring harness for reinstallation.

   Electrical Connector5 Nm (4 lb-ft)
4. 4

   Remove fan shroud cover screws
   Remove all cover screws securing the fan shroud upper cover or access panels. There are typically 4-6 screws around the perimeter. Set screws aside in a labeled container.
   Torque spec

   Cover Screws15 Nm (11 lb-ft)
5. 5

   Remove fan shroud mounting bolts
   Remove the fan shroud mounting bolts that secure the shroud assembly to the radiator support. On the 2014 Ram 2500 with 6.7L Cummins, there are typically 4 mounting bolts at the corners of the shroud. Carefully lift the top of the shroud away from the radiator.

   Mounting Bolts37 Nm (27 lb-ft)
6. 6

   Remove fan motor housing bolts
   With the shroud tilted or partially removed, access the fan motor housing bolts that secure the motor assembly to the fan shroud. Remove all housing bolts carefully, supporting the motor assembly to prevent it from falling.
   ⚠Support the fan motor assembly during bolt removal as it can be heavy and may damage radiator fins if dropped.

   Housing Bolts18 Nm (14 lb-ft)
7. 7

   Remove cooling fan motor from shroud
   Carefully separate the cooling fan motor assembly from the shroud. The motor may have fan blades attached - handle carefully to avoid bending blades. Remove the assembly from the engine compartment, tilting as necessary to clear the radiator and other components.
8. 8

   Transfer fan blades if necessary
   If the new fan motor does not include fan blades, remove the fan motor bolts securing the fan blade assembly to the old motor. Note the orientation and position of any spacers or washers. Install fan blades onto new motor in the same orientation.

   Fan Motor Bolts8 Nm (6 lb-ft)
9. 9

   Clean mounting surfaces
   Use a wire brush to clean all mounting surfaces on the fan shroud and inspect for cracks or damage. Clean debris from the radiator fins in the fan area. Replace any damaged gaskets or seals.
10. 10

    Install new fan motor to shroud
    Position the new fan motor assembly into the shroud, ensuring proper alignment of all mounting holes. Install the housing bolts and tighten in a cross pattern to the specified torque. Ensure the motor rotates freely without interference.

    Housing Bolts18 Nm (14 lb-ft)
11. 11

    Reinstall fan shroud assembly
    Carefully lower the fan shroud and motor assembly back into position over the radiator. Ensure fan blades are centered in the shroud opening and do not contact the shroud or radiator. Install all mounting bolts and tighten to specification in a cross pattern.

    Mounting Bolts37 Nm (27 lb-ft)
12. 12

    Reconnect electrical and install covers
    Connect the fan motor electrical connector firmly until it clicks into place. Secure the wiring harness in its original routing position. Install all shroud cover screws to specification.

    Electrical Connector5 Nm (4 lb-ft)

    Cover Screws15 Nm (11 lb-ft)
13. 13

    Reinstall hoses and refill coolant
    Reinstall the upper radiator hose and secure with hose clamps to specification. Reinstall air intake components. Refill the cooling system with the specified Mopar OAT Purple coolant to the proper level. Leave radiator cap off for now.

14. 14

    Bleed cooling system and test fan operation
    Reconnect the negative battery cable. Start the engine and allow it to reach operating temperature with the radiator cap off. Add coolant as needed and watch for proper fan operation when the engine reaches normal temperature. The fan should cycle on and off based on coolant temperature. Install radiator cap once coolant level is stable and system is burped of air.

Reassembly

1. Verify all electrical connectors are fully seated and secured
2. Confirm all bolts are torqued to specification and no fasteners are missing
3. Check coolant level after system reaches operating temperature and add as needed
4. Inspect for any coolant leaks around hose connections

Verification

• Start engine and verify cooling fan operates when engine reaches normal operating temperature (typically 190-210°F)
• Confirm fan speed changes appropriately based on cooling demand
• Listen for any unusual noises from the fan motor or blade assembly
• Verify no contact between fan blades and shroud throughout full rotation
• Check that engine maintains proper operating temperature under load
• Inspect for coolant leaks after test drive
• Verify cooling fan shuts off when engine cools below threshold temperature
