Solution

1. Preparation

Tools Required: Socket set, wrench set, OBD-II scanner, engine oil, torque wrench, stethoscope (optional).
Ensure the vehicle is parked on a flat surface and the engine is cool.
Disconnect the negative battery terminal to prevent electrical shorts.

2. Inspect and Secure Loose Components

Using a socket set, check and tighten any loose bolts or nuts on the engine components, including the intake and exhaust manifolds.
Use a stethoscope to listen for specific rattles while gently touching different parts of the engine.

3. Change Engine Oil and Filter

Drain the old engine oil using a wrench and oil drain pan.
Replace the oil filter using an oil filter wrench.
Refill the engine with manufacturer-recommended oil, ensuring the correct oil level.

4. Replace Worn Belts and Tensioners (if needed)

Remove the serpentine belt by releasing tension on the tensioner pulley using a wrench.
Inspect the belt for cracks or wear; replace if necessary.
Check the tensioner; if it is loose or noisy, replace it using the socket set.

5. Address Engine Mounts (if necessary)

Inspect engine mounts for cracks or deterioration.
To replace, support the engine with a jack and remove the bolts securing the mounts.
Install new mounts and torque to manufacturer specifications.
