Solution

1. Preparation

Gather necessary tools and parts.
Disconnect the negative battery terminal to ensure safety during repairs.

2. Check and Change Engine Oil

Locate the oil dipstick and check the oil level.
If the oil level is low, add the appropriate type of oil as specified in the owner's manual.
If oil is dirty or old, proceed to change the oil:
- Remove the oil drain plug with a socket wrench and let the old oil drain into a pan.
- Replace the oil filter using an oil filter wrench.
- Reinstall the drain plug and tighten to the manufacturer’s torque specifications.
- Refill the engine with fresh oil through the oil filler cap.

3. Inspect and Replace Valvetrain Components

Remove the engine cover by unscrewing all retaining bolts.
Inspect the rocker arms and lifters for damage or excessive wear.
If any components are damaged, replace them:
- Use a socket wrench to remove the old components.
- Install new components, ensuring they are torqued to manufacturer specifications.

4. Check the Serpentine Belt and Accessories

Inspect the serpentine belt for cracks or fraying.
If damaged, remove the old belt by releasing tension using a belt tensioner tool.
Install a new serpentine belt, ensuring it follows the correct routing as per the diagram located near the engine bay.

5. Inspect the Starter

Check the starter motor connections and ensure they are secure.
If the starter is suspected to be faulty, remove it by:
- Disconnecting electrical connectors.
- Unscrewing the mounting bolts.
Replace with a new starter and reconnect all components.
