Engine Cooling: 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.
• Cooling for:
  • The oil cooler.
  • The engine.
  • The electric throttle.
  • The Automatic Transmission Fluid (ATF) cooler.
• The supercharger.

The primary components of the engine cooling system are the:

• Coolant pump
• Thermostat
• Radiator
• Charge air radiator
• Charge air cooler coolant pump
• Electric cooling fan
• Oil cooler
• Coolant expansion tank
• Outlet pipe and heater manifold
• Thermostatic control valve
• Connecting hoses and pipes
• Auxiliary radiator (quantity 2).
