Solution

1. Preparation

Gather tools and parts needed.
Ensure the vehicle is parked on a level surface and the engine is cool.

2. Change Engine Oil

Sub-steps:
1. Drain Old Oil: Place an oil catch pan under the oil pan. Remove the drain plug and let the oil drain completely.
2. Replace Oil Filter: Remove the old oil filter using an oil filter wrench. Lubricate the rubber gasket of the new filter with a bit of new oil and install it.
3. Refill Engine Oil: Replace the drain plug and pour the recommended type and amount of new oil into the engine.

3. Adjust Valve Clearance (if applicable)

Sub-steps:
1. Remove Valve Cover: Disconnect any components obstructing access and remove the valve cover bolts. Carefully lift off the valve cover.
2. Measure Valve Clearance: Use a feeler gauge to measure the clearance of each valve. Adjust as necessary by loosening the lock nut and turning the adjustment screw.
3. Reinstall Valve Cover: Ensure the gasket is in good condition or replace it. Torque the valve cover bolts to the manufacturer’s specifications.

4. Inspect and Replace Timing Chain/Belt (if necessary)

Sub-steps:
1. Remove Front Engine Covers: Follow service manual instructions to remove covers obstructing access to the timing chain/belt.
2. Check Tensioner and Guides: Inspect the timing chain tensioner and guides for wear. Replace if necessary.
3. Install New Timing Chain/Belt: Align timing marks and install the new chain/belt according to manufacturer specifications.
