Solution

1. Preparation

Tools Required: Wrench set, oil catch pan, funnel, OBD-II scanner.
Sub-steps:
1. Ensure the vehicle is parked on a level surface.
2. Disconnect the negative battery terminal to prevent electrical issues.
3. Gather necessary tools and materials.

2. Check and Change Engine Oil

Tools Required: Oil filter wrench, socket set.
Sub-steps:
1. Remove the oil drain plug using a wrench and allow the old oil to drain into the pan.
2. Replace the oil filter with a new one.
3. Reinstall the drain plug and torque it to the manufacturer's specifications (typically 20-25 ft-lbs).
4. Refill the engine with the correct type and amount of engine oil (usually 5W-20 or 0W-20, depending on the model year).

3. Inspect and Adjust Valve Clearance (if applicable)

Tools Required: Feeler gauge, torque wrench.
Sub-steps:
1. Remove the valve cover to gain access to the valvetrain components.
2. Use a feeler gauge to check clearance between the rocker arms and valves.
3. Adjust the clearance as necessary by tightening or loosening the adjustment screws.
4. Reinstall the valve cover with a new gasket and torque to specification.

4. Check Timing Chain/Belt

Tools Required: Timing tool set, socket set.
Sub-steps:
1. Remove the timing cover to inspect the timing chain/belt.
2. Check for wear or slack in the chain/belt.
3. Replace the timing chain/belt if any wear is observed.
4. Reassemble the timing cover and ensure all bolts are torqued properly.
