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. Change Engine Oil and Filter

Sub-steps:
- Drain the old engine oil using a wrench to remove the oil drain plug and allow it to fully drain.
- Replace the oil filter with a new one. Use an oil filter wrench for removal and ensure the rubber O-ring is lubricated on the new filter before installing.
- Refill the engine with the recommended oil type (e.g., 5W-30) as specified in the owner’s manual.
- Recheck the oil level using the dipstick and add oil if necessary.

3. Inspect and Replace VVT Solenoid (if faulty)

Sub-steps:
- Locate the VVT solenoid, typically found on the cylinder head.
- Disconnect the electrical connector and remove the mounting bolts using a socket set.
- Remove the solenoid and inspect the O-ring for damage.
- Install the new VVT solenoid, ensuring a proper fit and sealing.
- Reconnect the electrical connector and tighten the bolts to the manufacturer’s torque specifications.

4. Verify Timing Chain/Belt Alignment

Sub-steps:
- Remove any necessary components (e.g., engine covers) to gain access to the timing chain/belt.
- Use a timing tool or reference marks to verify the alignment of the camshaft and crankshaft.
- If misaligned, follow the manufacturer's service manual to adjust the timing chain/belt correctly.
- Reassemble any removed components, ensuring all fasteners are properly torqued.
