Hi all,
I have 50,000 miles on my 04 Durango and figure it time to replace the belt.

Have you changed the serpintine belt and how much of a pain in the butt is it?

Thanks.

For all 2005 - I believe this would be identical to yours

REMOVAL- 3.7L/4.7L/5.7L

CAUTION: DO NOT LET TENSIONER ARM SNAP BACK TO THE FREEARM POSITION, SEVER DAMAGE MAY OCCUR TO THE TENSIONER.

Belt tension is not adjustable. Belt adjustment is maintained by an automatic (spring load) belt tensioner.

1. Disconnect negative battery cable from battery.
2. Rotate belt tensioner (6) until it contacts it's stop. Remove belt (2), then slowly rotate the tensioner (6) into the freearm position.

INSTALLATION:
Belt tension is not adjustable. Belt adjustment is maintained by an automatic (spring load) belt tensioner.

1. Check condition of all pulleys. CAUTION: When installing the serpentine accessory drive belt, the belt MUST be routed correctly. If not, the engine may overheat due to the water pump rotating in the wrong direction.

2. Install new belt. Route the belt around all pulleys except the idler pulley (5). Rotate the tensioner arm until it contacts it's stop position. Route the belt around the idler (5) and slowly let the tensioner rotate into the belt. Make sure the belt is seated onto all pulleys.

3. With the drive belt installed, inspect the belt wear indicator. On 4.7L Engines only, the gap between the tang and the housing stop (measurement A) must not exceed 24 mm (0.94 in.) . If the measurement exceeds this specification replace the serpentine accessory drive belt.
