Solution

1. Preparation

Tools Required: OBD-II scanner, mechanic’s stethoscope, socket set, torque wrench, feeler gauge.
Ensure the vehicle is parked on a level surface and the engine is cool. Disconnect the battery before starting any work.

2. Engine Oil Change

Sub-steps:
1. Raise the vehicle using a jack and secure it on jack stands.
2. Remove the oil drain plug using a socket wrench and drain the old oil into a suitable container.
3. Replace the oil filter using an oil filter wrench.
4. Install the drain plug and tighten to the manufacturer’s torque specifications.
5. Fill the engine with new oil according to the manufacturer’s specifications.

3. Valve Adjustment (if necessary)

Sub-steps:
1. Remove the engine cover to access the valve train.
2. Use a feeler gauge to measure the clearance between the rocker arm and the valve stem.
3. If out of specs, adjust the clearance by loosening the rocker arm adjustment nut and repositioning it.
4. Re-tighten the nut to the specified torque.

4. Timing Chain/Belt Inspection (if necessary)

Sub-steps:
1. Remove any components obstructing access to the timing cover (e.g., serpentine belt, crankshaft pulley).
2. Inspect the timing chain or belt for wear, slack, or damage.
3. Replace the timing chain or belt if necessary, following the manufacturer’s guidelines for tension and alignment.
