Generator Control Module Coolant Pump Replacement

Generator Control Module Coolant Pump Replacement

Removal Procedure

1. Drain the generator control module (GCM) cooling system. Refer to Generator Control Module Cooling System Draining and Filling. Generator Control Module Cooling System Draining and Filling
2. Remove the air cleaner assembly.
3. Remove the push pin from the right side radiator air baffle.
4. Remove the bolts (2) from the GCM coolant pump (1).
5. Reposition the GCM coolant pump (1) from the radiator core support (3).

6. Disconnect the electrical connector (1) from the GCM coolant pump (2).

7. Reposition the GCM coolant pump radiator hose clamp (2) from the GCM coolant pump (1).
8. Remove the GCM coolant pump radiator hose (3) from the GCM coolant pump (1).

9. Reposition the GCM coolant pump coolant hose clamp (1) from the GCM coolant pump (2).
10. Remove the GCM coolant pump coolant hose (4) from the GCM coolant pump (2).

Installation Procedure

1. Install the GCM coolant pump coolant hose (4) to the GCM coolant pump (2).
2. Position the GCM coolant pump coolant hose clamp (1) to the GCM coolant pump (2).

3. Position the GCM coolant pump radiator hose clamp (2) to the GCM coolant pump (1).
4. Install the GCM coolant pump radiator hose (3) to the GCM coolant pump (1).

5. Connect the electrical connector (1) to the GCM coolant pump (2).

6. Position the GCM coolant pump (1) to the radiator core support (3).

Notice: Refer to Fastener Notice.

7. Install the bolts (2) to the GCM coolant pump (1).

Tighten the bolts to 9 N.m (80 lb in).

8. Install the push pin to the right side radiator air baffle.
9. Install the air cleaner assembly.

Notice: The procedure below must be followed. Improper coolant level could result in a low or high coolant level condition, causing starter/generator control module damage.

10. Fill the GCM cooling system. Refer to Generator Control Module Cooling System Draining and Filling. Generator Control Module Cooling System Draining and Filling
