Description & Operation: Notes
WARNING:
To avoid the danger of being burned, do not remove the coolant recovery reservoir cap while the engine and radiator is still hot. Scalding fluid and steam may be blown out under pressure. Check the engine coolant level visually in the "see-through"reservoir. The level should be at or above the "FULL COLD" mark on the tank when the engine is cold. At normal operating temperatures the engine coolant level should be above the "FULL COLD" mark on the tank.
CAUTION:
When battery is disconnected, vehicle computer and memory systems may lose memory data. Driveability problems may exist until computer systems have completed a relearn cycle. See COMPUTER RELEARN PROCEDURES
article in GENERAL INFORMATION before disconnecting battery.
The electric cooling fan(s) are used to cool engine coolant flowing through the radiator. They are also used to cool the refrigerant flowing through the A/C condenser. See Fig 1 .
The electric cooling fan(s) are controlled by the Powertrain Control Module (PCM). The PCM controls the ground path for the cooling fan relay(s). See Fig 2 . The relay(s) are used to control the high current flow to power the cooling fan motors. The PCM determines operation of the independent fans based on various sensor inputs.
