Removal Procedure

WARNING: This page does not describe the selected car, but rather 6 other vehicles, including the 2003 GMC Savana Special, 2003 GMC Savana Camper Special, 2003 GMC Savana, 2003 Chevrolet RV Cutaway, and 2003 Chevrolet Cutaway. However, it is still accessible from the selected car via links, so may be relevant.
CAUTION: If a fan blade is bent or damaged, do not repair and use the damaged part. Replace a bent or damaged fan assembly with a new fan assembly. Using a fan with a different diameter, pitch, number of blades, or type of blade material may effect the cooling efficiency, performance and engine noise level.
  1. If a fan assembly fails, inspect the hub and the drive components. A fan assembly may fail due to an imbalance in the hub. This type of failure may not be the fault of the blades.
  2. Remove the upper fan shroud. Refer to Fan Shroud Replacement .
  3. Insert the J 38426  around the pulley in order to secure the pulley.

    Insert the J 38425  onto the fan clutch nut.

    • The fan (1)
    • The fan clutch (2)
  5. Inspect the following components for cracks, distortion, or other damage:
    • The belts
    • The hub
    • The adapter
    • The pulley
  6. Replace the components, as necessary.
