Solution

1. Preparation

Gather necessary tools and parts.
Ensure the vehicle is parked on a level surface and the engine is cool.
Disconnect the battery for safety.

2. Change Engine Oil

Sub-steps:
1. Drain the Old Oil:
  - Place an oil drain pan beneath the oil pan.
  - Remove the oil drain plug using a socket set and allow the oil to fully drain.
2. Replace Oil Filter:
  - Remove the old oil filter using an oil filter wrench.
  - Apply a small amount of new oil to the rubber gasket of the new filter and install it.
3. Add New Engine Oil:
  - Replace the drain plug and tighten it to the manufacturer’s torque specifications.
  - Fill the engine with the appropriate type and amount of engine oil as specified in the owner's manual.

3. Inspect and Adjust Valve Clearances (If Applicable)

Sub-steps:
1. Remove Valve Cover:
  - Use a socket set to remove the valve cover bolts and carefully lift off the valve cover.
2. Check Valve Clearances:
  - Use feeler gauges to measure the clearance between the valve and rocker arms.
  - Adjust the clearance to factory specifications as needed by adding or replacing shims.
3. Reinstall Valve Cover:
  - Clean the mating surfaces and apply new gasket material if necessary.
  - Reinstall the valve cover and tighten bolts to the specified torque.
