This is not one of the easiest ones but it isn't too bad to do.Make sure you use a block of wood between the jack and the oil pan.Only jack the engine enough to unbolt the mount at first until all the bolts are removed.Then if you need to jack it up more it will be okay.

Drive Belt Replacement


Removal Procedure

Notice: Routine inspection of the belt may reveal cracks in the belt ribs. These cracks will not impair the belt performance. The belt should be replaced if the belt slip occurs if a section of the belt ribs are missing. A single serpentine drive belt is used to drive all engine accessories. All belt driven accessories are rigidly mounted with the belt tension maintained by a spring loaded tensioner. The indicator on the movable portion of the tensioner must be within the limits of the marks of the stationary portion of the tensioner. Any reading outside of these limits indicates either a defective belt or tensioner.

  1. Install the engine mount assembly.

    Notice: Use the correct fastener in the correct location. Replacement fasteners must be the correct part number for that application. Fasteners requiring replacement or fasteners requiring the use of thread locking compound or sealant are identified in the service procedure. Do not use paints, lubricants, or corrosion inhibitors on fasteners or fastener joint surfaces unless specified. These coatings affect fastener torque and joint clamping force and may damage the fastener. Use the correct tightening sequence and specifications when installing fasteners in order to avoid damage to parts and systems.

    Tighten the bolt to 130 N·m (96 lb ft).
