Downloaded from www.Manualslib.com manuals search engine The cooling system regulates engine operating temperature. It allows the engine to reach normal operating temper-
ature as soon as possible, maintains normal operating temperature and prevents overheating.
The cooling system also provides a means of heating the passenger compartment. The cooling system is pressurized
and uses a centrifugal water pump to circulate coolant throughout the system.
The cooling system consists of the following components:
•Radiator
• Coolant
• Coolant pump
• Electric cooling fans
• Electric cooling fans control module
• Thermostat
• Coolant reservoir

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 coolant for heater
performance and cooling for automatic transmission oil. This is done by transferring heat from engine metal to cool-
ant, moving the heated coolant to the radiator, and then transferring the heat to the ambient air. Engine Coolant Flow Diagram - 1.6L & 1.8L & 2.0L
