Engine Cooling - INGENIUM I4 2.0L Petrol/INGENIUM I4 2.0L Petrol - PHEV (G2163177): Overview

The engine cooling system maintains the engine within an optimum temperature range under changing ambient and engine operating conditions. The system is a pressurized coolant expansion tank system with continuous bleeds to separate air from the engine coolant and prevent the formation of air locks. The engine cooling system also provides:

• Heating for:
  • The passenger compartment For additional information, Refer to: HEATING AND VENTILATION - INGENIUM I4 2.0L PETROL - PHEV and FUEL FIRED BOOSTER HEATER
  • The Automatic Transmission Fluid (ATF) cooler For additional information, Refer to: TRANSMISSION COOLING
• Cooling for:
  • The oil cooler For additional information, refer to: Engine - INGENIUM I4 2.0L Petrol
  • The engine For additional information, refer to: Engine - INGENIUM I4 2.0L Petrol
  • The electric throttle. For additional information, refer to: Intake Air Distribution and Filtering - INGENIUM I4 2.0L Petrol
