Engine Cooling - INGENIUM I4 2.0L Petrol (G2006258): 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
  • The electric throttle. For additional information, refer to: INTAKE AIR DISTRIBUTION AND FILTERING
• Cooling for:
  • The oil cooler For additional information, refer to: ENGINE
  • The engine For additional information, refer to: ENGINE
  • The Automatic Transmission Fluid (ATF) cooler For additional information, Refer to: TRANSMISSION COOLING - INGENIUM I4 2.0L PETROL
  • The charge air cooler For additional information, refer to: INTAKE AIR DISTRIBUTION AND FILTERING
  • The turbocharger. For additional information, Refer to: TURBOCHARGER

The primary components of the engine cooling system are the:

• Variable coolant pump
• Electric thermostat
• Radiator
• Electric cooling fan
• Coolant expansion tank
• Engine oil cooler
• Cylinder block inlet tube
• Auxiliary coolant pump
• Separator
• Connecting hoses and pipes
• Charge air cooler
• Charge air coolant pump
• Charge air radiator
• Auxiliary radiator
• ATF cooler
• Thermostatic valve - ATF cooler
• ATF warming valve

In cold climate markets, an active grille air shutter is installed to reduce aerodynamic drag and engine warm up time.

In hot climate markets, an additional auxiliary radiator is installed to improve the cooling capacity of the engine cooling system.
