Engine Cooling - V8 S/C 5.0L Petrol (G2154000): 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 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/TDV6 3.0L DIESEL/TDV8 4.4L DIESEL/V6 S/C 3.0L PETROL/V8 S/C 5.0L PETROL and FUEL FIRED BOOSTER HEATER

• Cooling for:
  • The oil cooler For additional information, refer to: ENGINE - V8 S/C 5.0L Petrol
  • The electric throttle For additional information, refer to: INTAKE AIR DISTRIBUTION AND FILTERING
  • The Automatic Transmission Fluid (ATF) cooler For additional information, Refer to: TRANSMISSION COOLING
• The supercharger. For additional information, refer to: SUPERCHARGER COOLING

The primary components of the engine cooling system are the:

• Coolant pump
• Electric thermostat
• Radiator
• Viscous cooling fan
• Electric cooling fan - If equipped
• Oil cooler
• Coolant expansion tank
• Heater manifold
• Thermostatic control valve
• ATF cooler
• Connecting hoses and pipes.

On North American Specification (NAS) market vehicles, an active grille air shutter is optionally installed to reduce aerodynamic drag and engine warm up time.
