Remove the old engine mount and install the new one, tightening bolts to manufacturer specifications.
Reconnect the battery and start the engine to check for vibrations.

3. Transmission Fluid Change

Tools Required: Fluid pump, socket set, drain pan, new transmission fluid
Locate the transmission fluid pan and remove the bolts to drain the old fluid.
Replace the transmission filter if applicable.
Reinstall the pan and fill with new transmission fluid using the fluid pump.
Check fluid levels and ensure the vehicle is running smoothly.

4. Spark Plug and Ignition Coil Inspection

Tools Required: Socket set, torque wrench
Remove the ignition coils from the spark plugs.
Inspect and replace any worn spark plugs and ignition coils.
Reinstall the ignition coils and ensure they are securely fastened.
