Here is the procedure. There is a special tool used to hold the fan pulley. If you do not have the tool, leave the drive belt in place, use a wrench on the fan clutch and strike the wrench with a hammer to break the fan clutch free.

  1. Remove the hood latch support. Object Number: 754345  Size: SH
