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 before working on electrical components.

2. Change Engine Oil and Filter

Sub-steps:
1. Place an oil drain pan under the oil pan.
2. Remove the oil drain plug using a socket wrench and allow the oil to drain completely.
3. Replace the oil filter using an oil filter wrench; lubricate the rubber O-ring on the new filter with fresh oil.
4. Reinstall the drain plug and torque it to the manufacturer’s specifications (typically 20-30 ft-lbs).
5. Refill the engine with the correct type and amount of oil (check the owner's manual for specifications).

3. Adjust Valve Clearance (if applicable)

Sub-steps:
1. Remove the valve cover by loosening the bolts with a socket set.
2. Rotate the engine to the appropriate position to access the valves.
3. Use a feeler gauge to measure the clearance; adjust using the rocker arm adjusters as necessary.
4. Reinstall the valve cover with a new gasket, ensuring proper torque on the bolts.

4. Inspect Timing Belt/Chain

Sub-steps:
1. Remove any obstructing components to access the timing belt/chain cover.
2. Check for signs of wear or damage on the belt/chain.
3. Replace the timing belt/chain and tensioner if any wear is detected, following the manufacturer's specifications for installation.
