Removal And Installation

WARNING: This page is about a different car, the 2003 Nissan Pathfinder. However, it is still accessible from the selected car via links, so may be relevant.

Do not release the drive belt tension by removing the fan pulley.
Fan coupling cannot be disassembled and should be replaced as a unit. If front mark F is present, install fan so that side marked F faces the front.
Install the drive belt only after the fan and fan coupling to fan pulley bracket flange bolts/nuts have been properly torqued.
