Operation 2.0/2.4L

The cooling systems primary purpose is to maintain engine temperature in a range that will provide satisfactory engine performance and emission levels under all expected driving conditions. The system does this by transferring heat from the engine metal to the coolant, then moves this heated coolant to the radiator where this heat is transferred to the ambient air. It also provides hot water (coolant) for heater performance and cooling for the automatic transmission oil.

- When the Engine is cold: The thermostat is closed and the cooling system has no flow through the radiator. The coolant flows through the engine, heater system which also serves as the bypass.
- When the Engine is warm: Thermostat is open and the cooling system has flow through the radiator, engine, heater system which also serves as the bypass.
