Installation Notes and Tips

Verify reverse rotation, electronic connector style, bolt pattern, and clutch dimensions before installation.

Confirm the fan bolt circle, pilot dimensions, and overall height against the original unit to ensure proper clearance and alignment.

For best results, inspect the cooling fan, shroud, and connector condition during replacement. This part number 46024 is intended for vehicles originally equipped with an electronic fan clutch and should be matched to the exact application listed in the fitment data.
