Generator Control Module Coolant Radiator Replacement

Generator Control Module Coolant Radiator 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 GCM coolant radiator outlet hose (1) from the GCM radiator (2).




3. Remove the ambient air temperature sensor (2) from the GCM coolant radiator bracket (3).




4. Disconnect the electrical connector from the GCM cooling fan.
5. Remove the bolts (1) from the GCM coolant radiator (5).
6. Remove the GCM coolant radiator (5) from the radiator core support (4).




7. Remove the bolts (4) from the GCM coolant fan (3).
8. Remove the GCM coolant fan (3) from the GCM coolant radiator (2).

Installation Procedure




1. Install the GCM coolant fan (3) to the GCM coolant radiator (2).

Notice: Refer to Fastener Notice.

2. Install the bolts (4) to the GCM coolant fan (3).

Tighten the bolts to 6 N.m (53 lb in).




3. Install the GCM coolant radiator (5) to the radiator core support (4).
4. Install the bolts (1) to the GCM coolant radiator (5).

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

5. Connect the electrical connector to the GCM coolant fan.




6. Install the ambient air temperature sensor (2) to the GCM coolant radiator bracket (3).




7. Install the GCM coolant radiator outlet hose (1) to the GCM radiator (2).

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.

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