Diagnostic Steps

2
Check for any abnormal noises from the engine while the vehicle is running.
3
Verify that all accessories driven by the serpentine belt (like the alternator, power steering pump, and AC compressor) are functioning properly.
4

Solution

1. Preparation

Tools Required: Socket set, ratchet, belt tensioner tool or wrench, flashlight, safety goggles.
Ensure the vehicle is parked on a level surface and the engine is turned off and cool.

2. Remove the Old Serpentine Belt

Open the hood and locate the serpentine belt routing diagram, usually found on a sticker near the radiator or on the engine cover.
Use the belt tensioner tool or wrench to relieve tension on the serpentine belt by rotating the tensioner pulley counterclockwise.
Carefully slide the belt off the pulleys while keeping tension off the belt.
Remove the belt from the tensioner and take it out of the engine bay.

3. Install the New Serpentine Belt

Compare the old belt with the new one to ensure proper size and type.
Begin routing the new belt according to the routing diagram, ensuring it sits properly in each pulley groove.
Slide the new belt onto the tensioner pulley last, while applying tension using the belt tensioner tool.
Double-check the belt alignment on all pulleys to ensure it is seated correctly.

4. Final Checks

Start the engine and let it idle for a few minutes.
Listen for any unusual noises and visually inspect the belt while the engine is running to ensure it is operating smoothly.
Turn on accessories (AC, power steering) to verify proper operation.
