Removal Procedure
Caution: Keep hands, tools, and clothing away from the electric engine coolant
fans in order to help prevent personal injury. These fans are electric and
can turn on whether or not the engine is running. The fans can start automatically
with the ignition in the ON position.
- Disconnect the negative battery cable. Refer to
Battery Negative Cable Disconnection and Connection
in Engine
Electrical.
- Disconnect the intake
air temperature (IAT) and mass airflow (MAF) sensors electrical connectors,
if equipped with the 5.7L engine.
- Remove the air intake
duct resonator, if equipped with the 5.7L engine.
- Disconnect the electrical
connector from the intake air temperature (IAT) sensor, if equipped with the
3.8L engine.
- Remove the air intake
duct resonator, if equipped with the 3.8L engine.
- Disconnect the rosebud
clips from the fans.
- Disconnect the coolant
fan electrical connectors from the fans.
- Remove the air cleaner
bolts.
- Remove the air cleaner.
- Remove the electric engine
coolant fan. The fan will slide off of the radiator.
- Remove the fan blade nut.
Caution: If a fan blade is bent or damaged in any way, do not repair or reuse
the damaged part. Always replace a bent or damaged fan blade. Fan blades that
have been damaged can not be assured of proper balance and could fail and
fly apart during subsequent use. This creates an extremely dangerous situation.
The fan blades must remain in proper balance. You cannot assure fan
blade balance once a fan blade has been bent or damaged. A fan blade that
is not in proper balance could fail and fly apart during use, creating an
extremely dangerous situation.
- Remove the fan blade.
- Inspect for the following conditions:
• | Bent or cracked fan blades |
• | Smoothness of the fan blade mating surfaces |
• | Remove burrs or other imperfections as necessary |
Installation Procedure
