Installation

1. NOTE: 5.0L engine shown, 3.7L engine similar.

   Position the A/C compressor belt in 2 stages.
   • Stage 1: Slide the A/C compressor belt between the crankshaft pulley and the accessory drive belt tensioner.
   • Stage 2: Position the A/C compressor belt behind the crankshaft pulley with the accessory drive belt ribs facing towards the front of the vehicle.

   • NOTE: Make sure the A/C compressor belt is correctly seated on the A/C compressor pulley.

     Stage 3: Position the A/C compressor belt onto the A/C compressor pulley with the lower portion of the accessory drive belt ribs facing towards the front of the vehicle and above the oil pan as shown.

2. NOTE: 5.0L engine shown, 3.7L engine similar.

   NOTE: After installation, make sure the A/C compressor belt is correctly seated on the crankshaft and A/C compressor pulleys.

   Position the A/C compressor belt onto the top of the crankshaft pulley and feed a tie strap with a minimum width of 3 mm (0.12 in) through the crankshaft pulley spokes, up and over the A/C compressor belt and tighten the tie strap.

3. NOTICE: The A/C compressor belt must be above the oil pan flange or damage to the A/C compressor belt and engine can occur.

   NOTE: 5.0L engine shown, 3.7L engine similar.

   With the A/C compressor belt positioned above the oil pan flange, rotate the crankshaft by hand clockwise until the tie strap is at the 6 o'clock position.

4. NOTE: 5.0L engine shown, 3.7L engine similar.

   NOTE: After installation, make sure the A/C compressor belt is correctly seated on the crankshaft and A/C compressor pulleys.

   Remove the tie strap and rotate the crankshaft clockwise 1 full rotation to verify the A/C compressor belt has correctly seated onto the crankshaft and A/C compressor pulleys.

5. Install the accessory drive belt. For additional Information, refer to Accessory Drive Belt — 3.7L , or Accessory Drive Belt — 5.0L (4V) in this section.
