Solution

1. Preparation

Gather all necessary tools and parts.
Ensure the vehicle is parked on a level surface and the engine is cool.
Disconnect the battery to prevent electrical shock or shorts.

2. Inspect and Replace Fluids

Engine Oil:
1. Remove the oil dipstick and check oil level; top off if low.
2. If oil is burnt or dirty, drain old oil using a wrench and replace with new oil (SAE 0W-20).
3. Replace the oil filter if necessary.
Coolant:
1. Check the coolant reservoir; if low, add the appropriate coolant type (Toyota Long Life Coolant).
2. Inspect the radiator for leaks and ensure the cap is secure.

3. Inspect and Replace Serpentine Belt

Visually inspect the serpentine belt for cracks, fraying, or burning.
If damaged, use a socket set to relieve tension on the belt tensioner and remove the old belt.
Install a new serpentine belt according to the routing diagram (usually found on a sticker in the engine bay).

4. Check Electrical Components

Inspect wiring harnesses, connectors, and fuses for any signs of burning or melted plastic.
Replace any damaged wires or connectors with appropriate parts.
