Solution

1. Preparation

Gather necessary tools and parts.
Disconnect the battery to ensure safety while working on the vehicle.
Raise the vehicle with jack stands if working underneath.

2. Oil Change (if oil is contaminated/low)

Sub-steps:
1. Remove the oil drain plug with a socket set and allow the old oil to drain completely.
2. Replace the oil filter using an oil filter wrench.
3. Install the new oil filter and tighten it to manufacturer's specifications.
4. Reinstall the drain plug and torque to the specified value.
5. Fill the engine with new oil, ensuring it meets manufacturer specifications.

3. Inspect and Replace Air Filter (if necessary)

Sub-steps:
1. Locate the air filter housing and unclip or unscrew it.
2. Remove the old air filter and inspect for damage or contamination.
3. Insert a new air filter, ensuring a snug fit to prevent air leaks.
4. Reassemble the housing and secure it.

4. Compression Test (if low compression is suspected)

Sub-steps:
1. Remove the spark plugs using a spark plug socket.
2. Insert the compression tester into the spark plug hole.
3. Crank the engine for a few seconds to take a reading.
4. Repeat for each cylinder and record the results.
5. Compare results to manufacturer specifications.

5. Inspect Belts and Pulleys

Sub-steps:
1. Visually inspect all belts and pulleys for signs of wear, cracks, or looseness.
2. Replace any worn or damaged belts using appropriate tools.
3. Ensure all pulleys rotate freely and are properly aligned.
