Installation Notes:

• Verify 2.56" pilot diameter matches your fan hub before ordering
• Inspect fan clutch for wear during replacement
• Torque mounting bolts to manufacturer specifications
• Check blade-to-radiator clearance after installation (32" diameter requires adequate space)
• Ensure proper alignment to prevent vibration
• Verify fan shroud compatibility with large diameter blade

Warning signs you need replacement: Visible cracks or chips, warping, heat discoloration, unusual vibration, or engine running hotter than normal.
