Solution

1. Preparation

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

2. Inspect Engine Oil

Sub-steps:
- Remove the oil dipstick and wipe it clean.
- Reinsert the dipstick and remove it again to check the oil level; add oil if low.
- If oil is dirty or contaminated, proceed to an oil change.
Tools Required: Oil filter wrench, socket set, oil catch pan.

3. Replace Engine Oil and Filter (if necessary)

Sub-steps:
- Use the oil catch pan to drain the old oil completely.
- Replace the oil filter using the oil filter wrench.
- Refill the engine with the manufacturer-recommended oil type and quantity.
Tools Required: Oil catch pan, oil filter wrench, funnel.

4. Inspect Timing Chain/Belt

Sub-steps:
- Remove any components obstructing access to the timing cover.
- Visually inspect the timing chain/belt for wear, slack, and proper tension.
- If any issues are found, replace the timing chain/belt and tensioner.
Tools Required: Socket set, torque wrench.

5. Inspect and Adjust Valve Clearance (if applicable)

Sub-steps:
- Remove the valve cover to access the valvetrain.
- Check the valve clearance using a feeler gauge; adjust as necessary to manufacturer specifications.
- Reinstall the valve cover with a new gasket to prevent leaks.
Tools Required: Socket set, feeler gauge, torque wrench.
