Should i put anti seize on fan clutch nut?

It's generally not recommended to apply anti-seize to the fan clutch nut, as it may affect the proper torque and can lead to over-tightening or loosening. The fan clutch nut should be installed dry to ensure it bonds correctly and maintains the necessary tension. If you’re concerned about corrosion, a light application of a suitable lubricant (not anti-seize) may be appropriate, but always refer to the manufacturer's specifications for guidance.
