Solution

1. Preparation

Gather necessary tools and parts.
Disconnect the negative battery terminal to prevent electrical shorts.
Allow the engine to cool down.

2. Check and Change Engine Oil

Sub-steps:
1. Drain the old engine oil using an oil drain pan.
2. Replace the oil filter.
3. Refill with the correct specification engine oil (e.g., 0W-20).
4. Start the engine and let it idle for a few minutes to circulate the new oil.
Tools Required: Oil filter wrench, oil drain pan, socket set.

3. Inspect and Replace VVT Solenoid

Sub-steps:
1. Locate the VVT solenoid (usually found on the front of the engine, near the camshaft).
2. Disconnect the electrical connector from the VVT solenoid.
3. Remove the solenoid using the appropriate socket size.
4. Install the new VVT solenoid and torque it to the manufacturer specification (typically around 10 Nm).
5. Reconnect the electrical connector.
Tools Required: Socket set, torque wrench.

4. Verify Camshaft Timing

Sub-steps:
1. Remove the timing cover to access the timing belt/chain.
2. Align the timing marks on the crankshaft and camshaft.
3. If misaligned, adjust the timing belt/chain accordingly and ensure it is tensioned properly.
4. Reinstall the timing cover and torque bolts to specification.
Tools Required: Torque wrench, timing tool kit.
