- Remove the underhood storage unit (refer to procedure).
- Disconnect the harness connections (x2):
- Powertrain coolant pump connector (red arrow)
- Coolant level sensor connector (yellow arrow)
- Clamp the hose from the reservoir to the 4-way valve. Ensure
that the clamp is placed just below the spring clamp on the
reservoir.
- From the LH wheelwell (RH for RHD), clamp the hose from the
powertrain coolant pump to the rocker hose. Ensure that the clamp is
placed just outside of the spring clamp.

reservoir upper bracket to the strut brace (torque 5 Nm).
- Release the 1 nut that secures the coolant reservoir upper
bracket (torque 5 Nm).
- Release the bolts (x2) that secure the coolant reservoir to the
crossmember (torque 5 Nm).
Note: RHD vehicles have a refrigerant pipe routed very close to these bolts. Use a long extension to remove the bolts.
- Release the 2 fasteners that secure the coolant reservoir bracket.
- Release the spring clamps (x2). Caution: Do not remove the clamps that were placed on the hoses in steps 5 and 6.
- Remove the coolant reservoir and powertrain coolant pump
assembly from the vehicle.
Caution: Plug the hoses to prevent ingress of moisture or dirt.
- For RHD vehicles, remove the bolt that secures the bracket to
the pump (torque 4 Nm).
