Solution

1. Preparation

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

2. Inspect and Replace Oil Filter

Sub-steps:
1. Locate the oil filter.
2. Use an oil filter wrench to remove the old oil filter.

4. Install the new oil filter by hand, ensuring it is snug but not over-tightened.

3. Check and Replace Oil

Sub-steps:
1. Remove the oil drain plug using a socket wrench.
2. Allow all old oil to drain completely into a suitable container.
3. Replace the oil drain plug and tighten it to the manufacturer's torque specifications (typically around 25-30 ft-lbs).
4. Refill the engine with the appropriate type and amount of oil (check the owner’s manual for specifications).

4. Inspect and Reconnect Hoses

Sub-steps:
1. Visually inspect all vacuum hoses around the engine compartment for any disconnections or damage.
