Solution

1. Preparation

• Gather all necessary tools and parts.
• Ensure the vehicle is parked on a level surface and the engine is cool.
• Disconnect the battery to ensure safety before working on electrical components.

2. Engine Oil Inspection and Change

• Sub-steps:
  1. Remove the oil dipstick and check the oil level.
  2. If oil is low or dirty, drain the old oil using a socket set to remove the oil pan drain plug.
  3. Replace the oil filter using an oil filter wrench.
  4. Refill with the recommended engine oil (5W-20 for most models) and replace the drain plug.

Tools Required:

• Socket set
• Oil filter wrench
• Oil catch pan

3. Inspect and Replace Damaged Components

• Sub-steps:

  3. Replace any damaged or worn components, including engine mounts or heat shields.

Tools Required:

• Wrench set
• Torque wrench (for specified torque values)

4. Compression Test

• Sub-steps:
  1. Remove spark plugs using a spark plug socket.
  2. Insert the compression gauge into the spark plug hole.
  3. Crank the engine and record the compression readings for each cylinder.
  4. Compare readings to manufacturer specifications; replace components as necessary if readings are low.

Tools Required:

• Compression gauge
• Spark plug socket

5. Timing Chain/Belt Inspection

• Sub-steps:
  1. Remove the timing cover using a socket set to expose the timing chain/belt.
  2. Inspect for wear, tension, or misalignment.
  3. Replace the timing chain/belt if it shows signs of damage according to service manual specifications.
