Gather tools and parts required for the repair.
Disconnect the negative battery terminal to prevent electrical shorts.
Allow the engine to cool before starting work.

2. Change Engine Oil and Filter

Sub-steps:
1. Raise the vehicle using a jack and secure it on jack stands.
2. Place an oil drain pan under the oil pan and remove the drain plug.
3. Allow the oil to fully drain, then replace the drain plug.
4. Remove the old oil filter using an oil filter wrench.
5. Install the new oil filter, lubricating the rubber gasket with new oil.
6. Refill the engine with the correct type and amount of oil as specified in the owner’s manual.

3. Replace VVT Solenoid

Sub-steps:
1. Locate the VVT solenoid, typically near the camshaft cover.
2. Disconnect the electrical connector from the solenoid.
3. Remove the mounting bolts securing the solenoid and take it out.
4. Install the new VVT solenoid, ensuring it is seated properly.
5. Reconnect the electrical connector.

4. Inspect and Adjust Timing Chain/Belt

Sub-steps:
1. Remove any components obstructing access to the timing chain/belt (e.g., engine covers).
2. Check the tension of the timing chain/belt; adjust or replace if necessary.
3. Align timing marks on the camshaft and crankshaft according to the manufacturer specifications.
4. Reinstall any components removed during access.

5. Clear Codes and Test Drive
