Solution

1. Preparation

Gather all necessary tools and parts.
Ensure the engine is cool and disconnect the negative battery terminal to prevent electrical shock.

2. Remove Ignition Coils

Sub-steps:
1. Locate the ignition coil packs on top of the engine, secured by bolts.
2. Remove the bolts using a socket set and carefully lift the ignition coils off the spark plugs, taking care not to damage any connectors.

Tools Required: Socket set, ratchet

3. Remove Spark Plugs

Sub-steps:
1. Use a spark plug socket and ratchet to carefully unscrew each spark plug from the cylinder head.
2. Inspect the removed spark plugs for damage or excessive wear.

Tools Required: Spark plug socket, ratchet

4. Install New Spark Plugs

Sub-steps:
1. Apply a small amount of anti-seize compound to the threads of the new spark plugs (if applicable).
2. Install the new spark plugs by hand, then tighten them to the manufacturer’s specified torque (typically around 13-15 lb-ft).

Tools Required: Torque wrench

5. Reinstall Ignition Coils

Sub-steps:
1. Position the ignition coils back over the spark plugs.
2. Secure them with the bolts removed earlier, ensuring they are tightened to the manufacturer’s specifications.

Tools Required: Torque wrench

6. Reconnect Battery

Reconnect the negative battery terminal and ensure all connections are secure.
