This procedure covers removal and replacement of the front engine mount on a 2014 Ram 2500 with 6.7L Cummins diesel engine, requiring engine support and frame bolt removal.

Warnings

Tools required

Parts

• Front engine mount assembly × 1 — Use OEM Mopar mount or equivalent quality

Preparation

1. Park vehicle on level surface and engage parking brake
2. Disconnect negative battery cable to prevent accidental starter engagement
3. Raise front of vehicle and support securely on jack stands at frame rails
4. Remove engine cover if equipped by removing cover bolts
5. Inspect work area and identify front engine mount location between engine block and frame

Procedure

1. 1

   Support engine weight
   Position hydraulic jack with wooden block under oil pan or install engine support fixture across engine compartment. Raise jack or fixture to just contact engine and take up slack, but do not lift engine yet. Ensure support is centered and stable.
   ⚠️Use wood block between jack and oil pan to distribute load and prevent oil pan damage. Do not support engine by transmission pan.
2. 2

   Remove front skid plate if equipped
   Remove bolts securing front skid plate or belly pan to access engine mount from below. Set aside hardware for reinstallation.
3. 3

   Remove mount through-bolt
   Locate and remove the large through-bolt that passes horizontally through the engine mount assembly connecting the upper and lower mount sections. This bolt passes through the rubber isolator. Use penetrating oil if bolt is seized.
4. 4

   Raise engine slightly
   Using the engine support jack or fixture, raise engine approximately 10-15mm (0.5 inch) to relieve tension on the mount. Raise slowly and watch for interference with other components. Stop if excessive resistance is felt.
   ⚠Do not raise engine more than necessary. Monitor hoses, wiring, and accessories for tension or binding.
5. 5

   Remove engine mount-to-block bolts
   Remove the bolts securing the upper portion of the engine mount bracket to the engine block. There are typically 2-3 bolts on the engine side. Support mount with one hand while removing final bolt.
   Torque spec

   Engine Mount-to-Block Bolts65 Nm (48 lb-ft)
6. 6

   Remove mount-to-frame bolts
   Remove the bolts securing the lower mount bracket to the frame rail. These bolts attach vertically through the frame mounting points. Note orientation and position of any washers or spacers.
   Torque spec

   Engine Mount-to-Frame Bolts75 Nm (55 lb-ft)
7. 7

   Remove old engine mount
   With all fasteners removed, carefully extract the engine mount assembly from between the engine and frame. May require slight prying or wiggling to free mount from mounting surfaces. Inspect mount for signs of failure such as torn rubber, fluid leakage, or separated components.
8. 8

   Clean mounting surfaces
   Thoroughly clean both engine block mounting surface and frame mounting surface. Remove any rust, dirt, or old gasket material. Inspect mounting holes for thread damage or stripping.
9. 9

   Install new engine mount
   Position new engine mount assembly between engine and frame, aligning mounting holes. Ensure mount orientation matches original installation with rubber isolator properly positioned. May need to adjust jack height slightly for alignment.
10. 10

    Install and torque mount-to-frame bolts
    Install bolts securing lower mount bracket to frame rail. Start all bolts by hand first, then torque to specification in a cross pattern if multiple bolts. Ensure any washers or spacers are in correct position.
    Torque spec

    Engine Mount-to-Frame Bolts75 Nm (55 lb-ft)
11. 11

    Install and torque engine mount-to-block bolts
    Install bolts securing upper mount bracket to engine block. Start all bolts by hand, then torque to specification. Verify mount bracket is seated flush against engine block.
    Torque spec

    Engine Mount-to-Block Bolts65 Nm (48 lb-ft)
12. 12

    Lower engine and install through-bolt
    Slowly lower engine using jack or support fixture until weight is resting on new mount and rubber isolator is properly compressed. Install mount through-bolt and torque to specification. Verify mount is not twisted or bound.
13. 13

    Remove engine support and reinstall components
    Carefully remove engine support jack or fixture. Reinstall front skid plate if equipped and torque mounting bolts appropriately. Reinstall engine cover if removed and torque cover bolts to specification.

Reassembly

1. Reconnect negative battery cable
2. Lower vehicle from jack stands
3. Verify no tools or parts are left in engine compartment
4. Check that all fasteners are properly torqued and secure

Verification

• Start engine and observe mount for excessive movement or vibration
• With engine idling, shift transmission through all gears and verify mount holds engine securely without excessive deflection
• Listen for any unusual clunking or knocking noises during acceleration and deceleration
• Perform test drive and verify no abnormal vibrations or engine movement under acceleration and braking
• Re-inspect all mount bolts after 50-100 miles of driving to ensure they remain tight
