Solution

1. Preparation

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

2. Check and Change Engine Oil

Tools: Oil filter wrench, socket set, oil catch pan, funnel.
Remove the oil drain plug and allow the old oil to drain completely into the catch pan.
Replace the oil filter using the oil filter wrench.
Reinstall the drain plug and torque to the manufacturer’s specifications.
Add the recommended type and amount of engine oil through the filler cap.

3. Inspect and Adjust Valve Clearances

Tools: Torque wrench, feeler gauge, socket set.
Remove the valve cover to access the valvetrain.
Use a feeler gauge to check the clearance of each valve.
Adjust the clearances as necessary by replacing shims or adjusting the rocker arms.
Reinstall the valve cover with a new gasket and torque to specifications.

4. Inspect Timing Belt/Chain

Tools: Socket set, torque wrench.
Remove any covers obstructing access to the timing belt/chain.
Check the tension and condition of the timing belt/chain.
Replace if worn or if tension is not within specified range.
