Solution

1. Preparation

Gather necessary tools and parts.
Ensure the vehicle is parked on a level surface and the engine is cool.

2. Inspect and Replace Engine Mounts

Tools Required: Socket set, torque wrench, pry bar
Steps:
1. Lift the Vehicle: Use a jack and jack stands to safely elevate the front of the vehicle.
2. Remove Engine Cover: If applicable, take off the engine cover to access the mounts.
3. Inspect Mounts: Visually inspect for cracks, tears, or excessive wear.
4. Remove Old Mounts: Unbolt the engine mounts from the engine block and subframe using a socket set.
5. Install New Mounts: Position the new engine mounts and torque to manufacturer specifications (usually around 25-30 Nm).
6. Reinstall Engine Cover: If removed, replace the engine cover securely.

3. Transmission Fluid Check and Replacement

Tools Required: Transmission fluid pump, socket set, drain pan
Steps:
1. Locate the Transmission Pan: Identify the transmission pan and drain plug.
2. Drain Old Fluid: Use a drain pan to collect old fluid by removing the drain plug.
3. Replace Filter: If applicable, remove and replace the transmission filter.
4. Add New Fluid: Use a fluid pump to refill the transmission with the correct type of fluid, typically around 6-8 quarts for a complete change.
5. Check Fluid Level: Start the engine and cycle through the gears, checking the fluid level and topping off as necessary.

4. Inspect and Replace Spark Plugs

Tools Required: Socket set, spark plug socket, torque wrench
Steps:
1. Remove Ignition Coils: Unbolt and disconnect the ignition coils from the spark plugs.
2. Remove Old Spark Plugs: Use a spark plug socket to carefully unscrew each spark plug.
3. Install New Spark Plugs: Apply anti-seize compound on threads and torque to manufacturer specifications (usually around 25 Nm).
4. Reinstall Ignition Coils: Bolt the ignition coils back into place and reconnect the wiring.
