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 avoid any electrical issues during repairs.

2. Inspect and Replace Worn Belts

Inspect the serpentine belt:
- Remove the engine cover (if applicable) using a socket set.
- Visually check the belt for signs of wear, fraying, or glazing.
Replace if necessary:
- Loosen the tensioner using a wrench and remove the old belt.
- Install the new belt following the routing diagram typically located on the engine cover.
- Tighten the tensioner to secure the new belt.

3. Address Brake Components

Inspect brake system:
- Remove the wheel to access brake components.
- Check for caliper operation, ensuring it is not sticking.
- Inspect brake pads for wear; replace if they are worn down excessively.
Replace brake pads (if necessary):
- Remove old pads and clean the caliper.
- Install new pads, ensuring they are properly seated and secured.

4. Check and Change Engine Oil

Inspect engine oil:
- Remove the dipstick and check oil level and condition.
Change oil if necessary:
- Drain the old oil using an oil drain pan.
- Replace the oil filter using an oil filter wrench.
- Refill with the manufacturer-recommended oil type and quantity.
