When it comes to maintaining the performance and efficiency of your vehicle, one of the most crucial components to pay attention to is the spark plugs. Over time, spark plugs can wear out and lose their effectiveness, leading to decreased fuel efficiency, poor engine performance, and even damage to other engine components. If you own a 2017 Chevy Malibu, it’s essential to know how to change spark plugs to keep your vehicle running smoothly and prolong its lifespan. In this comprehensive guide, we’ll walk you through the step-by-step process of replacing spark plugs on your 2017 Chevy Malibu, covering the necessary tools, precautions, and techniques to ensure a successful and stress-free experience.
Preparation and Planning
Before you start, make sure you have the following tools and materials:
| Spark plug socket (14mm or 5/8 inch) | Spark plug gap gauge | Socket wrench or ratchet | New spark plugs (correct type and number) | Rubber gloves | Wheel chocks (optional) |
Additionally, it’s recommended to consult your owner’s manual or a repair manual specific to your vehicle for specific instructions and recommendations. It’s also a good idea to take your vehicle for a test drive to identify any potential issues or problems that may affect the spark plug replacement process.
Removing the Spark Plug Wires
To access the spark plugs, you’ll need to remove the spark plug wires. Start by locating the spark plug wires, which are usually attached to the spark plug boots. You’ll need to remove the spark plug wire boots by pulling them straight off the spark plug.
Next, use a spark plug wire puller to gently pull the spark plug wires off the spark plug. Be careful not to touch any of the spark plug wires or boots to any metal surfaces, as this can cause damage to the spark plug wires or the spark plugs.
Spark Plug Wire Puller Options
There are two main types of spark plug wire pullers: manual and automatic. Manual spark plug wire pullers require you to manually pull the spark plug wire off the spark plug, while automatic spark plug wire pullers use a spring-loaded mechanism to pull the spark plug wire off the spark plug.

Removing the Spark Plugs
Once the spark plug wires are removed, you can start removing the spark plugs. Use a spark plug socket to remove the spark plug. Insert the spark plug socket into the spark plug well and turn it counterclockwise until the spark plug is loose.
Once the spark plug is loose, use a socket wrench or ratchet to remove the spark plug from the spark plug well. Be careful not to touch any of the spark plug threads or the spark plug well to any metal surfaces, as this can cause damage to the spark plug or the spark plug well.
Spark Plug Socket Options
There are two main types of spark plug sockets: standard and deep. Standard spark plug sockets are designed for spark plugs with standard threads, while deep spark plug sockets are designed for spark plugs with deep threads.
| Standard Spark Plug Socket | Deep Spark Plug Socket |
For the 2017 Chevy Malibu, it’s recommended to use a standard spark plug socket to remove the spark plugs.
Installing the New Spark Plugs
Once the old spark plugs are removed, you can start installing the new spark plugs. Use a spark plug socket to install the new spark plug. Insert the spark plug into the spark plug well and turn it clockwise until it’s snug.
Once the spark plug is snug, use a socket wrench or ratchet to tighten the spark plug an additional 1/4 to 1/2 turn. Be careful not to overtighten the spark plug, as this can cause damage to the spark plug or the spark plug well.
Spark Plug Gap Setting
Before installing the new spark plugs, it’s essential to set the spark plug gap to the recommended specification. The spark plug gap is the distance between the center electrode and the ground electrode of the spark plug. (See Also: Can Spark Plugs Cause Poor Gas Mileage? Find Out)

Make sure the spark plug wires are securely attached to the spark plugs and the spark plug boots are securely attached to the spark plug wires.
Final Check and Test Drive
