Solution

1. Preparation

Gather tools and parts.
Ensure the vehicle is parked on a flat surface and the engine is cool.
Disconnect the battery to prevent any electrical shorts during inspection.

2. Inspect Engine Components

Remove any engine covers as necessary using a socket set.
Check for oil leaks around the oil pan and valve covers; replace any damaged gaskets.
Inspect the serpentine belt for fraying or glazing; replace if necessary.

3. Brake System Inspection

Remove the wheel to access the brake components.
Inspect brake pads for wear; replace if thinner than 3mm.
Check brake rotors for heat spots or warping; machine or replace as needed.
Ensure brake calipers are functioning properly; replace if seized.

4. Transmission Fluid Check

Locate the transmission dipstick, remove it, and wipe it clean.
Reinsert dipstick and check fluid level; add recommended transmission fluid if low.
If the fluid appears dark or has a burnt smell, consider a transmission fluid change.

5. Reassemble and Test

Reinstall any covers or components removed during inspection.
Reconnect the battery and ensure all tools are accounted for.
Start the vehicle and check for any leaks or unusual noises before taking it for a test drive.
