2. Replace Serpentine Belt (if worn)

Sub-steps:
1. Disconnect the negative battery cable to prevent electrical issues.
2. Use a socket to release tension on the belt tensioner and remove the belt from the pulleys.
3. Compare the old belt with the new belt for size and compatibility.
4. Install the new belt following the correct routing diagram located under the hood.
5. Reapply tension using the tensioner and ensure the belt is seated on all pulleys.

3. Replace or Adjust Tensioner (if defective)

Sub-steps:
1. Remove the serpentine belt as described in Step 2.
2. Unbolt the tensioner from its mounting bracket using a socket set.
3. Install the new tensioner in the reverse order of removal and torque to manufacturer specifications.
4. Reinstall the serpentine belt.

4. Inspect/Replace Worn Suspension Components (if applicable)

Sub-steps:
1. Lift the vehicle using a jack and secure it with jack stands.
2. Inspect bushings, ball joints, and struts for signs of wear or damage.
3. Replace any worn components using appropriate tools and torque specifications.
4. Lower the vehicle back to the ground.
