How to Replace a Serpentine Belt on a 2003 Dodge Pickup
by Matthew FergusonSome vehicles employ multiple belts to drive the engine accessories. Conveniently, the 2003 Dodge pickup uses just one--a serpentine belt. The serpentine belt follows a circuitous path along the front of the engine, passing over the various engine accessory pulleys. For a 2003 Dodge pickup, the serpentine belt should be checked every 6,000 miles or six months, and replaced if frayed or worn. A worn belt will have a shiny (glazed) appearance due to friction caused by operation.
Belt removal
Step 1
Open the hood of the vehicle after turning the engine off. Locate the tensioner assembly. Like the engine accessories surrounding it, the tensioner features a pulley, over which the serpentine belt passes. There is a bolt at the center of this pulley.
Step 2
Rotate the bolt, using a socket wrench, to release tension on the belt. For standard Dodge V6 and V8 models, the tensioner will rotate clockwise. For heavy-duty V8 and V10 Dodge pickups, the tensioner will rotate counter-clockwise.
Step 3
Separate the loosened serpentine belt from each pulley, then remove the belt from the engine compartment.
Step 4
Release the tensioner bolt gradually.
Belt installation
Step 1
Rotate the tensioner pulley in the same manner as above.
Step 2
Route the replacement serpentine belt over the various pulleys. If you're unsure of the proper routing, study the belt routing decal printed on the top of the radiator.
Step 3
Release the belt tensioner carefully, allowing the belt to settle in place.
