Disconnect the battery to prevent any electrical short circuits.

2. Inspect and Replace Engine Belts

Sub-steps:
1. Visually inspect the serpentine belt for cracks, fraying, or glazing.
2. If damaged, loosen the tensioner using a socket wrench.
3. Remove the old belt by sliding it off the pulleys.
4. Install a new serpentine belt by routing it according to the belt routing diagram.
5. Re-tighten the tensioner to the specified torque (typically 15-20 ft-lbs).

Socket set
Torque wrench

3. Check for Fluid Leaks

Sub-steps:
1. Inspect the area beneath the vehicle for any fluid drips.
2. Check the oil level and coolant level; refill if necessary.
3. If any fluids are leaking onto hot components, repair the source of the leak (e.g., replace gaskets or hoses).
