Solution

1. Preparation

Gather tools and parts required for the repair.
Disconnect the vehicle's battery to ensure safety.
Allow the engine to cool down before starting work.

2. Change Engine Oil and Filter

Sub-steps:
1. Raise the vehicle using a jack and secure it with jack stands.
2. Remove the oil drain plug using a socket set, and allow the old oil to drain completely.
3. Replace the oil filter using an oil filter wrench.
4. Reinstall the oil drain plug and torque it to manufacturer specifications (typically around 25 Nm).
5. Fill the engine with new oil, using the manufacturer's recommended oil type (usually 5W-30 synthetic).

3. Replace VVT Solenoid

Sub-steps:
1. Locate the VVT solenoid, typically found near the camshaft cover.
2. Disconnect the electrical connector from the solenoid.
3. Remove the mounting bolts securing the solenoid and carefully take it out.
4. Install the new VVT solenoid and torque the bolts to the specified value.
5. Reconnect the electrical connector.

4. Inspect and Adjust Timing Chain/Belt

Sub-steps:
1. Remove the engine cover to access the timing chain/belt.
2. Check the timing marks and ensure they align according to manufacturer specifications.
3. If misaligned, adjust the chain/belt tension using the appropriate tensioner tool.
4. Reinstall the engine cover securely.
