Solution

1. Preparation

Gather tools and parts for the repair.
Park the vehicle on a level surface and engage the parking brake.
Disconnect the negative battery terminal to ensure safety.

2. Inspect and Replace Engine Oil

Sub-steps:
1. Remove the oil drain plug using a socket set and drain the engine oil into a catch pan.
2. Replace the oil filter with a new one, ensuring the old gasket is removed.
3. Reinstall the drain plug and torque to the manufacturer’s specifications (typically 20-25 lb-ft).
4. Refill the engine with fresh oil as specified in the owner’s manual.
Tools Required: Socket set, oil filter wrench, catch pan, funnel.

3. Replace Worn Engine Mounts

Sub-steps:
1. Support the engine with a jack and a block of wood.
2. Remove the bolts securing the old engine mount using a socket set.
3. Position the new engine mount in place and secure it with the original bolts, torquing to the manufacturer’s specifications.
Tools Required: Jack, block of wood, socket set.

4. Inspect and Tighten Exhaust Components

Sub-steps:
1. Inspect the exhaust system visually for loose brackets or damaged pipes.
2. Tighten any loose bolts or clamps using a ratchet and socket.
3. Replace any damaged components as needed.
Tools Required: Ratchet and socket set.

5. Replace Spark Plugs

Sub-steps:
1. Remove the ignition coil or spark plug wires carefully.
2. Use a spark plug socket to remove the old spark plugs.
3. Install new spark plugs to the specified torque (typically around 13-16 lb-ft).
4. Reconnect ignition coils or spark plug wires.
Tools Required: Spark plug socket, ratchet, torque wrench.
