Maintenance
Visually inspect cooling system components for damage, and/or
misalignment.
Primary system components requiring noise related inspection include fan
blades, fan clutch, fan shroud, fan ring, and recirculation shields. Check fan
blades, fan ring, fan shroud, belt tensioner and recirculation shields for any
damage. Verify that fan blades clear the fan ring. Inspect all related fasteners,
brackets, and clamps for damage and tightness. Confirm operation of
temperature modulated fan clutch.
