Solution

1. Preparation

• Gather tools and parts required for the repair.
• Ensure the vehicle is parked on a level surface and the engine is cool.
• Disconnect the negative battery terminal to prevent electrical shorts.

2. Inspect and Replace the VVT Solenoid

• Tools Required: Socket set, torque wrench, ratchet, oil catch pan.
• Sub-steps:
  1. Locate the VVT solenoid; it is typically mounted on the engine near the camshaft.
  2. Disconnect the electrical connector from the VVT solenoid.
  3. Remove the bolts securing the solenoid and take it out of the engine.
  4. Inspect the old solenoid for any signs of wear or damage.
  5. Install the new VVT solenoid and torque the bolts to the manufacturer's specifications (usually around 10-15 Nm).
  6. Reconnect the electrical connector.

3. Change Engine Oil and Filter

• Tools Required: Oil filter wrench, socket set, oil catch pan, funnel.
• Sub-steps:
  1. Place the oil catch pan under the oil pan and remove the drain plug to drain the old oil completely.
  2. Replace the oil filter using the oil filter wrench.
  3. Install the drain plug and torque it to the manufacturer's specifications (usually around 25 Nm).
  4. Fill the engine with new oil as per the manufacturer’s recommendation (typically 5W-30 or 0W-40).
  5. Start the engine and let it idle for a few minutes to circulate the new oil.

4. Check Timing Chain/Belt

• Tools Required: Timing tool kit (if applicable), socket set, torque wrench.
• Sub-steps:
  1. If the timing chain/belt is suspected to be an issue, remove the necessary components to access it.
  2. Inspect for wear, proper alignment, and tension.
  3. If any issues are found, replace the timing chain/belt according to the manufacturer’s specifications.
