Solution

1. Preparation

Tools Required: Socket set, ratchet, OBD-II scanner, engine oil, oil filter, wrench set, jack and jack stands, safety goggles, gloves.
Safety Warnings: Disconnect the battery before working on electrical systems and allow the engine to cool before starting repairs.

2. Replace Faulty Engine Mounts

Sub-steps:
1. Lift the vehicle using a jack and secure it on jack stands.
2. Remove the lower engine cover if necessary for access.
3. Locate the engine mounts and inspect them for cracks or deterioration.
4. If damaged, use a socket set to remove the bolts securing the engine mount.
5. Install the new engine mount and torque the bolts to the manufacturer’s specifications (check service manual for torque values).

3. Inspect and Replace Accessory Belts

Sub-steps:
1. Locate the serpentine belt and inspect for signs of wear or looseness.
2. If worn, loosen the tensioner using a wrench to release the belt.
3. Remove the old belt and install the new one, ensuring it follows the correct routing.
4. Tighten the tensioner to hold the new belt in place.

4. Change Engine Oil and Filter

Sub-steps:
1. Warm up the engine slightly to thin the oil for easier draining.
2. Turn off the engine and allow it to cool for a few minutes.
3. Place a drain pan under the oil pan and remove the drain plug with a socket set, allowing the oil to drain completely.
4. Replace the oil filter using an oil filter wrench.
5. Reinstall the drain plug and torque it to the specified value.
6. Fill the engine with new oil through the oil filler cap, checking the level with the dipstick.
