FAN BLADE

This engine cooling fan blade is designed for heavy-duty diesel trucks. It features 11 blades on a 30-inch diameter, rotating clockwise to pull air through the radiator. The fan mounts to the fan clutch via a 2.56-inch pilot hole and a 3.5-inch bolt circle. It is typically replaced when blades become damaged, cracked, or unbalanced, which can cause engine overheating or vibration.
