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 electrical
connectors from the (IAT) intake air temperature sensor and (MAF) mass airflow
sensor, if equipped with the 5.7L (VIN G) engine.
- Remove the air intake
duct, if equipped with the 5.7L (VIN G) engine.
- Disconnect the electrical
connector from the (IAT) intake air temperature sensor, if equipped with the
3800 (VIN K) engine.
- Remove the air intake
duct, if equipped with the 3800 (VIN K) engine.
- Disconnect the rosebud
clips from the fan assembly.
- Disconnect the coolant
fan electrical connectors from the fan assembly.
- Remove the air cleaner
assembly bolts.
- Remove the air cleaner assembly.
- 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
- Install the fan blade.
- Install the fan blade nut.
- Install the electric engine coolant fan. The fan will slide into
place on the radiator.
- Install the air cleaner
assembly.
- Install the air cleaner assembly bolts.
Tighten
Tighten the air cleaner bolts to 12 N·m (106 lb in).
- Connect the coolant fan
electrical connectors to the fan assembly.
- Connect the rosebud clips
to the fan assembly.
- Install the air intake
duct, if equipped with the 3800 (VIN K) engine.
- Connect the electrical
connector to the IAT sensor, if equipped with the 3800 (VIN K) engine.
- Install the air intake
duct, if equipped with the 5.7L (VIN G) engine.
- Connect the electrical
connectors to the IAT sensor and the MAF sensor, if equipped with the 5.7L
(VIN G) engine.
