Solution

1. Preparation

Gather necessary tools and parts.
Disconnect the negative battery terminal to ensure safety.
Raise the vehicle if necessary and secure it on jack stands.

2. Inspect and Change Engine Oil

Sub-steps:
1. Remove the oil drain plug using a socket wrench.
2. Allow old oil to drain completely into an oil catch pan.
3. Replace the oil filter with a new one; ensure the rubber O-ring is lubricated.
4. Reinstall the drain plug and torque it to the manufacturer’s specifications (typically around 30 ft-lbs).
5. Fill the engine with fresh oil, using the recommended viscosity as per the owner’s manual.
Tools Required: Socket set, oil filter wrench, oil catch pan, funnel.
Safety Warnings: Ensure the engine is cool before draining oil. Dispose of old oil and filter properly.

3. Replace VVT Solenoid

Sub-steps:
1. Locate the VVT solenoid (usually near the camshaft).
2. Disconnect the electrical connector from the solenoid.
3. Remove the mounting bolts securing the solenoid to the engine.
4. Remove the old solenoid and replace it with the new one, ensuring correct orientation.
5. Reinstall the mounting bolts and torque them to specification.
6. Reconnect the electrical connector.
Tools Required: Socket set, torque wrench.
Safety Warnings: Disconnect the battery before working on electrical components.

4. Check Timing Chain/Belt

Sub-steps:
1. Remove any necessary components to gain access to the timing cover.
2. Inspect the timing chain/belt for any signs of wear or damage.
3. If misaligned or damaged, replace the timing chain/belt following manufacturer guidelines.
4. Reassemble all components in reverse order, ensuring all bolts are torqued correctly.
Tools Required: Socket set, timing tool kit (if needed).
Safety Warnings: Ensure all timing marks are aligned correctly during reassembly.
