Solution

1. Preparation

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

2. Oil Change (if oil condition is poor)

Tools Required: Oil filter wrench, socket set, oil drain pan, funnel.
Sub-steps:
1. Remove the oil drain plug using a socket set and allow the old oil to drain completely into the pan.
2. Replace the oil filter using the oil filter wrench.
3. Reinstall the drain plug and torque it to manufacturer specifications (usually around 30 lb-ft).
4. Refill the engine with the recommended oil type (typically 0W-20 for Honda Civic) through the oil fill cap.

3. Inspect and Replace Engine Mounts (if damaged)

Tools Required: Socket set, jack and jack stands.
Sub-steps:
1. Lift the vehicle using a jack and secure it with jack stands.
2. Locate the engine mounts underneath the vehicle.
3. Remove bolts securing the damaged mounts using a socket set.
4. Replace with new mounts and torque bolts to specifications.
5. Lower the vehicle and reconnect the battery.

4. Inspect Exhaust System (if leaks are found)

Tools Required: Wrench set, exhaust clamps, exhaust sealant.
Sub-steps:
1. Visually inspect the exhaust for cracks or holes.
2. Tighten any loose connections or replace damaged sections using exhaust clamps.
3. Apply exhaust sealant where necessary to ensure a proper seal.
