Solution

1. Preparation

Tools Required: Socket set, torque wrench, OBD-II scanner, mechanic's stethoscope.
Ensure the vehicle is parked on a level surface and the engine is cool.
Disconnect the battery to avoid any electrical issues during inspection.

2. Engine Oil Inspection and Replacement

Check engine oil level using the dipstick; if low, top off with the recommended oil type (5W-20).
If oil appears dirty or old, perform an oil change:
1. Remove the oil drain plug using a socket wrench and drain the old oil into a pan.
2. Replace the oil filter.
3. Reinstall the drain plug and torque to manufacturer specifications (typically around 20 lb-ft).
4. Fill with new oil to the appropriate level.

3. Inspect and Replace Engine Mounts (if necessary)

Tools Required: Socket set, jack, jack stands.
Lift the vehicle using a jack and secure it with jack stands.
Remove the bolts securing the engine mounts with a socket wrench.
Replace any damaged mounts with new ones, ensuring they are torqued to specifications.
Lower the vehicle back down.

4. Inspect Timing Chain/Belt

Remove the engine cover (if applicable) using a socket set.
Check the tension of the timing chain; adjust or replace if loose or worn.
If timing components are worn, replace the timing chain/belt and tensioner according to manufacturer specifications.

5. Inspect Exhaust Components

Visually inspect heat shields and exhaust pipes for any loose or damaged sections.
Secure any loose components and replace damaged ones.
