Solution

1. Preparation

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

2. Inspect and Replace Belts

Inspect Serpentine and Timing Belts:
- Remove the engine cover if obstructed.
- Check both belts for cracks, frays, or signs of melting.
Replace Damaged Belts:
- Loosen the tensioner bolt using a socket set and remove the old belt.
- Install the new serpentine belt, ensuring it is routed properly according to the belt diagram.
- Tighten the tensioner to secure the new belt.

3. Brake System Check

Inspect Brake Components:
- Lift the vehicle using a jack, and secure it with jack stands.
- Remove the wheel to access the brake assembly.
- Inspect brake pads for wear and ensure calipers are functioning properly.
Replace Worn Components:
- If brake pads are worn, remove them and install new pads.
- Check caliper movement; if stuck, consider replacing the caliper.

4. Fluid Check and Replacement

Check Engine Oil and Coolant:
- Inspect the oil dipstick; if oil is dark or low, change the oil and filter.
- Check the coolant reservoir; ensure proper fluid levels are maintained.
Top Off or Replace Fluids:
- Add new oil or coolant as necessary, following manufacturer specifications.

5. Final Assembly

Reattach any covers removed during inspection.
Reconnect the battery.
Ensure all tools are removed from the engine bay.
