3. If the belt is damaged, loosen the tensioner and remove the belt.
4. Install a new serpentine belt, ensuring it is routed correctly according to the belt routing diagram.
Tools Required: Socket set, belt tensioner tool (if applicable)

3. Check and Change Transmission Fluid

Sub-steps:
1. Locate the transmission dipstick and remove it to check fluid level.
2. If low, add the appropriate transmission fluid (consult owner’s manual for specifications).
3. If fluid is dark or burnt, drain the transmission fluid and replace with fresh fluid.
4. Replace the transmission filter if applicable.
Tools Required: Fluid pump, wrench set, transmission fluid

4. Inspect CV Joints and Axles

Sub-steps:
1. Lift the vehicle using a jack and secure it with jack stands.
