Removal
- Position the vehicle on a lift, but do not raise it at this time.
- Remove the 12V battery bracket beam (refer to procedure).
-
Release the 2 fir tree clips that secure the 12V positive harness to the front crossmember.
-
Move the 12V positive harness to the RH side of the vehicle to keep it out of the working area.
-
Release the 4 bolts that secure the coolant reservoir to the front crossmember (torque 6 Nm). Do not remove the reservoir at this time.
CAUTIONAt this point in the procedure, there are still 2 coolant hoses and 1 harness attached to the reservoir.
-
Carefully lift up the coolant reservoir and disconnect the coolant level sensor harness.
-
Ensure that the cap on the reservoir is properly secured, then pull the reservoir forward into the underhood area.
NoteThe reservoir hose is routed behind the drive unit hose. Note the routing of the hoses and ensure that they are routed correctly during reinstallation.
-
Gently pull down on the 2 coolant hoses to release the clips (x4) that secure them to the front crossmember.
-
Release the clip that secures the coolant reservoir hose to the A/C line.
-
On the LH side of the 3-way fitting, clamp the coolant hose that leads to the differential housing. Remove the hose from the front drive unit and plug the nipple.
-
Move the coolant reservoir to the LH side of the vehicle and secure it out of the working area.
CAUTIONThe reservoir is still secured to 2 coolant hoses.
- Resecure the coolant hose to the front drive unit, but do not engage the locking ring at this time.
- Release the 2 bolts that secure each fuse box to the front crossmember (torque 5 Nm). Move both fuse boxes behind the front crossmember.
-
Release the bolt that secures the bracket for coolant pump 3 (torque 6.5 Nm). Move the bracket behind the front crossmember.
-
Position the support jack on top of the front crossmember and secure the 2 screws to the front crossmember.

Release the 2 bolts and washers that secure the LH side motor mount to the body (torque 65 Nm).
NoteEnsure that the 2 bolts that secure the LH mount to the body each have a washer.
-
Remove and discard the 3 bolts that secure the motor to the LH motor mount (torque 38 Nm):
- Raise the vehicle to access the LH wheelwell.
- Use a deep socket to release the rear bolt.
- Lower the vehicle.
- Working from the underhood area, release the front 2 bolts.
- Remove the LH motor mount from the vehicle.
Installation
- Loosen the bolts that secure the 2 sections of the LH motor mount.
- Set the new motor mount into position.
-
Secure the 3 bolts that secure the motor to the LH motor mount (torque 38 Nm).
-
