Solution

1. Preparation

Gather necessary tools and materials.
Ensure the vehicle is parked on a flat surface and the engine is cool.
Disconnect the battery to prevent any electrical issues.

2. Check Engine Oil

Remove the oil dipstick, clean it, and reinsert it to check the oil level.
If the oil level is low, add manufacturer-recommended oil until the proper level is reached.
If the oil is dirty or contaminated, proceed to change the oil and oil filter.
- Tools Required: Wrench set, oil filter wrench, oil catch pan.

3. Inspect Spark Plugs and Ignition Coils

Remove the ignition coil covers and inspect the coils for cracks or damage.
Remove the spark plugs using a spark plug socket.
Check the condition of the spark plugs; replace them if they show signs of wear (e.g., deposits, wear on the electrode).
- Tools Required: Spark plug socket, torque wrench.

4. Inspect Engine Mounts

Visually inspect the engine mounts for cracks or excessive wear.
If any mounts are damaged, replace them with new mounts.
- Tools Required: Jack and jack stands, socket set.

5. Check Drive Belts and Pulleys

Inspect the drive belts for fraying, cracks, or stretching.
Ensure that the pulleys are aligned and not wobbling.
Replace any worn or damaged belts as necessary.
- Tools Required: Socket set, belt tensioner tool.
