Solution

1. Preparation

• Tools Required: OBD-II scanner, socket set, torque wrench, multimeter, timing tool set.
• Ensure the engine is cool and disconnect the negative battery terminal for safety.

2. Change Engine Oil

1. Drain Old Oil: Remove the oil drain plug and allow oil to fully drain into a pan.
2. Replace Oil Filter: Remove the old oil filter using an oil filter wrench and install a new one.
3. Add New Oil: Replace the drain plug and fill the engine with the manufacturer-recommended oil type and quantity.

4. Remove Solenoid: Unscrew the mounting bolts and carefully remove the solenoid.
5. Install New Solenoid: Position the new solenoid, secure it with bolts, and reconnect the electrical connector.

4. Check Timing Chain/Belt

1. Remove Necessary Components: Depending on access, remove the serpentine belt and any covers obstructing the timing chain/belt.
2. Align Timing Marks: Rotate the engine to align the timing marks on the camshaft and crankshaft.
3. Inspect for Wear: Check for any signs of wear or damage on the timing chain/belt. Replace if necessary.

5. Clear Codes and Test

1. Reconnect Battery: Reconnect the negative terminal of the battery.
