Cooling System: Description and Operation

DESCRIPTION AND OPERATION
The cooling system includes:
1. A radiator.
2. A water thermostat that is located in the water hose connection which is attached to the rear of the lower intake manifold.
3. A water pump that has a conventional design and is driven by the drive belt.
4. Two cooling fan motors. The cooling fan motors are mounted within a fan shroud behind the radiator. The Constant Control Relay Module (CCRM) actuates the cooling fan motors when:
a. The engine coolant reaches a specified temperature.
b. The engine reaches a specified speed.
c. The A/C clutch is activated.

NOTE: With A/C ON, the cooling fan motors will run continuously. Cooling fan motors will not cycle ON and OFF with A/C clutch. An exception to this is when vehicle speed is over 61 km/h (38 mph) and coolant temperature is below 100° C (212° F), and A/C head pressure is below 250 psi. The cooling fan motors will then automatically shut off.

5. A radiator coolant recovery reservoir which is located on the right side of engine compartment, which helps to maintain the correct volume of engine coolant.
