Safety Warning
DIY auto repair can cause serious injury, fire, or vehicle damage. These guides are for informational purposes only. Always follow OEM torque specs, wear PPE, and consult a certified mechanic if you are unsure. You are solely responsible for your safety.
SGCM Cooling System Coolant Cycle
The starter/generator control module (SGCM) coolant is a 50/50 mixture of DEX-COOL antifreeze and clean, drinkable water. The coolant is drawn from the SGCM coolant tank by the SGCM coolant pump. The coolant pump then forces the coolant through the SGCM coolant radiator. The coolant then is sent to the SGCM to cool the SGCM electronics.
