Solution

1. Preparation

Gather necessary tools and parts.
Ensure the vehicle is parked on a flat surface and the engine is cool.
Disconnect the negative battery terminal to prevent electrical shorts.

2. Inspect and Replace Serpentine Belt

Remove the engine cover (if applicable) using a socket set.
Use a belt tensioner tool to relieve tension on the serpentine belt.
Carefully remove the serpentine belt from the pulleys.
Inspect the belt for cracks, fraying, or signs of burning. Replace if necessary.
Install the new serpentine belt, following the routing diagram usually located on the engine cover.
Reattach the engine cover and reconnect the battery terminal.

3. Brake System Inspection

Safely lift the vehicle using a jack and secure it with jack stands.
Remove the wheel to access the brake assembly.
Inspect brake pads for excessive wear or glazing.
Check calipers for proper operation and heat damage.
Replace any damaged components (pads, calipers) as needed.
Reassemble the wheel and lower the vehicle.

4. Fluid Checks

Inspect the transmission fluid level using the dipstick (if applicable).
If the fluid is burnt or discolored, drain and replace the transmission fluid and filter according to manufacturer specifications.
Inspect engine oil levels and look for any leaks around the oil pan or seals.
If oil is leaking, replace worn seals or gaskets.
