Installation
3.5L GTDI, 3.7L, 5.0L (4V) Early Build Vehicles
1. NOTE: 5.0L (4V) engine shown, 3.5L and 3.7L engines 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 (4V) engine shown, 3.5L and 3.7L engines 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 (4V) engine shown, 3.5L and 3.7L engines 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 (4V) engine shown, 3.5L and 3.7L engines 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.
5.0L (4V) Late Build Vehicles
5. Position the A/C drive belt and rotate the drive belt tensioner clockwise and attach the A/C compressor drive belt to the idler pulley.
