Generator Control Module Coolant Pump
WARNING: This page is about a different car, the 2007 Saturn Vue. However, it is still accessible from the selected car via links, so may be relevant.
The generator control module coolant pump is a serviceable component which is connected to the vehicle cooling system and the module cold plate using separate, serviceable hoses. The pump augments the engine driven water pump to ensure adequate coolant flow to the cold plate.
