Disconnect the negative battery terminal if working on electrical components.

2. Inspect and Replace Serpentine Belt

Step 1: Visually inspect the serpentine belt for cracks, fraying, or glazing.
Step 2: If damage is found, loosen the tensioner using a socket and ratchet to release tension on the belt.
Step 3: Remove the old belt and install a new serpentine belt, ensuring proper routing according to the belt diagram.
Tools Required: Socket set, serpentine belt tool (optional).

3. Check and Refill Power Steering Fluid

Step 1: Locate the power steering reservoir and check the fluid level.
Step 2: If low, add the appropriate power steering fluid (consult owner’s manual for specifications).
Step 3: If the fluid is dirty or contaminated, consider flushing the power steering system.
Tools Required: Funnel, appropriate power steering fluid.

4. Inspect and Replace Alternator

Step 1: Remove the serpentine belt from the alternator.
Step 2: Disconnect the electrical connector and battery cables from the alternator.
Step 3: Remove the mounting bolts and replace the alternator with a new one.
Step 4: Reconnect the electrical connector and battery cables, then reinstall the serpentine belt.
Tools Required: Socket set, wrench set.

5. Inspect Transmission Fluid

Step 1: Locate the transmission dipstick (if applicable) and check the fluid level and condition.
