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 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:
Cooling for:
- The engine.
For additional information, refer to: Engine (303-01B Engine -
INGENIUM I4 2.0L Diesel, Description and Operation).
- The engine oil cooler.
For additional information, refer to: Engine (303-01B Engine -
INGENIUM I4 2.0L Diesel, Description and Operation).
- The automatic transmission fluid (ATF) cooler.
For additional information, refer to: Transmission Cooling (307-02
Transmission/Transaxle Cooling, Description and Operation).
- The exhaust gas recirculation (EGR).
The primary components of the engine cooling system are the:
- Coolant pump - variable
- Radiator
- Electric cooling fan
- Coolant expansion tank
- Electric thermostat
- ATF Cooler
- Engine oil cooler
- Connecting hoses and pipes.
- Cylinder block heater
In cold climate markets, an optional block heater is available as a dealer
fit
accessory. The block heater is located in the cylinder block and is connected
to a power supply via an external plug.
