Solution

1. Preparation

Gather tools and parts needed for repair.
Ensure the vehicle is parked on a level surface and the engine is cool.
Disconnect the battery to prevent electrical issues during repair.

2. Engine Oil Change

Sub-steps:
1. Place a drain pan under the oil pan.
2. Remove the oil drain plug using a socket set and let the old oil drain completely.
3. Replace the oil drain plug and torque it to manufacturer specifications (typically around 30 ft-lbs).
4. Remove the old oil filter using an oil filter wrench.
5. Lubricate the rubber gasket on the new oil filter with new oil and install it.
6. Fill the engine with the appropriate grade of engine oil (typically 0W-20 for this model).
7. Start the engine and let it run for a few minutes, then check for leaks.

3. Inspect and Repair Exhaust System

Sub-steps:
1. Raise the vehicle using a jack and secure it with jack stands.
2. Visually inspect the entire exhaust system for rust, damage, or loose connections.
3. Tighten any loose bolts or clamps found on the exhaust system.
4. Replace any damaged sections of the exhaust as necessary.
5. Lower the vehicle and start the engine to check for noise reduction.

4. Engine Mount Replacement

Sub-steps:
1. Identify the engine mounts by referring to the service manual.
2. Support the engine with a jack and a block of wood to avoid damage.
3. Remove the bolts securing the damaged engine mount using a socket set.
4. Replace the engine mount with a new one, ensuring proper alignment.
5. Torque the bolts to the specified value as per the service manual.
6. Remove the jack and start the engine to check for noise reduction.
