Solution

1. Preparation

Gather tools and parts needed for repair.
Disconnect the battery to avoid electrical shorts.
Allow engine to cool before commencing work.

2. Change Engine Oil and Filter

Sub-steps:
1. Place a drain pan under the oil pan and remove the oil drain plug using a socket wrench.
2. Allow old oil to fully drain, then replace the drain plug and torque it to the manufacturer’s specifications (typically 25 ft-lbs).
3. Replace the oil filter using an oil filter wrench; ensure the rubber O-ring from the old filter is removed.
4. Apply a small amount of new oil to the rubber O-ring of the new filter and install it.
5. Fill the engine with the appropriate grade of oil as specified in the owner’s manual (typically 0W-20 for this model).

3. Inspect and Replace Engine Mounts

Sub-steps:
1. Raise the vehicle securely on jack stands and remove the front underbody cover if necessary.
2. Locate the engine mounts and inspect for cracks, wear, or separation.
3. If any mounts are damaged, remove the bolts securing the mount to the chassis and engine using a socket set.
4. Install new engine mounts and torque the bolts to the manufacturer’s specifications (usually around 40 ft-lbs).
5. Lower the vehicle and recheck for any vibrations.

4. Check and Replace Spark Plugs

Sub-steps:
1. Remove the ignition coil cover if applicable, and disconnect the ignition coils.
2. Use a spark plug socket to remove the old spark plugs.
3. Inspect the spark plugs for wear; replace with new OEM spark plugs if necessary.
4. Torque the new spark plugs to the manufacturer’s specifications (typically 13 ft-lbs).
5. Reinstall the ignition coils and cover.
