Solution

1. Preparation

Gather tools and parts needed for repair.
Ensure the vehicle is parked on a flat surface and the engine is off.
Tools Required: Socket set, OBD-II scanner, torque wrench, flashlight.

2. Inspect and Repair Exhaust System

Sub-steps:
1. Raise the vehicle using jack stands.
2. Visually inspect the exhaust pipes, muffler, and joints for signs of rust, holes, or loose connections.
3. If a leak is found, replace the damaged section of the exhaust pipe or muffler using a pipe cutter and exhaust clamps.
4. Ensure all hangers and brackets are secure.

3. Check and Change Engine Oil

Sub-steps:
1. Remove the oil dipstick to check oil level and condition.
2. If oil is low or dirty, drain the old oil using a wrench to remove the oil drain plug.
3. Replace with manufacturer-recommended oil and new filter.
4. Torque the drain plug to 20 lb-ft (27 Nm) upon reinstallation.

4. Inspect Engine Mounts

Sub-steps:
1. Visually inspect all engine mounts for cracks or separation.
2. If a mount is damaged, use a socket set to remove the bolts securing the mount.
3. Replace with a new engine mount and torque bolts to the manufacturer's specifications.

5. Check Intake System

Sub-steps:
1. Inspect the air intake duct and hoses for cracks or disconnections.
2. Tighten any loose connections and replace damaged components as needed.
