Cooling System

DESCRIPTION
The cooling system consists of an engine cooling module, thermostat, coolant, a water pump to circulate the coolant. The engine cooling module may consist of a radiator, electric fan motor, shroud, radiator pressure cap, coolant reserve system, transmission oil cooler and lines, hoses, clamps, and air conditioning condenser.

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













The coolant flow circuits for 2.0L and 2.4L engine equipped vehicles are shown. The 2.5L engine coolant flow circuit is shown.
