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.
