Introduction

Use this guide to replace spark plugs for a 2019 Honda Civic.

Based on how often a vehicle is used and the kind of the car, spark plugs should be replaced in intervals of 20,000 to 100,000 miles. Old or damaged spark plugs ultimately cause engine damage. Hard starts, reduced gas mileage, engine misfiring, and lack of acceleration are the symptoms of defective spark plugs.

Before using this guide, make sure the engine and cylinder heads are cold. Also, make sure you repeat the steps for installing all four spark plugs before reinstalling the engine cover.

Tools

Use a wrench to remove the bolts on the top of the engine cover.
Remove the engine cover.

Step 2

Detach the clamps of the wire holder to disconnect it.
Put a screwdriver under the small panel on the wire connector and lift the panel.
Separate the cable from the wire connector.

Step 3

Use the wrench to remove the bolt that is placed beside the wire connector.
Simply pull out the connector.

Step 4

Make sure the spark plug area is dry before removing the spark plug.
Attach the socket to the socket wrench.
Put the socket inside the cylinder head and twist the socket wrench to remove the spark plug.

Step 5

Inspect the new spark plug to ensure that it is completely dry.

Step 6

Remove the old spark plug and attach the new spark plug to the socket.
Place the socket back in the cylinder head and twist the socket wrench to install the spark plug.
