How to Change Spark Plugs in a 2007 Dodge Caliber
To change the spark plugs in a 2007 Dodge Caliber, you can follow these general steps:
1. Gather the necessary tools and materials: new spark plugs, a T30 Torx bit and ratchet, a 5/8 inch spark plug socket, and a gap tool.
2. Open the hood and locate the four ignition coils, which are located on top of the engine.
3. Disconnect the harness connected to each ignition coil by pushing the tab and pulling it off.
4. Use a T30 Torx bit and ratchet to remove the T30 Torx bolt that secures each ignition coil.
5. Once the bolt is removed, lift the ignition coil straight up to expose the spark plug underneath.
6. Use a 5/8 inch spark plug socket and a socket wrench to remove the spark plug by turning it counterclockwise.
7. Inspect the old spark plug for any signs of damage or wear. If necessary, adjust the gap on the new spark plug using a gap tool to match the manufacturer’s specifications.
8. Install the new spark plug by threading it into the spark plug socket and carefully lowering it into the engine.
9. Use the socket wrench to tighten the spark plug by turning it clockwise. Be careful not to overtighten it, as this can damage the threads.
10. Repeat these steps for each spark plug, one at a time, until all four spark plugs have been replaced.
It’s important to note that these steps are a general guide and may vary slightly depending on the specific model and engine of your Dodge Caliber. For more detailed instructions, you can refer to video tutorials available on platforms like YouTube.

Two spark plugs provide a faster burn. It starts the combustion from two sides of the cylinder and burns toward the center. A faster burn generally provides more power and a more complete burn. The Hemi isn’t a high reving engine, but high reving racing engines use two spark plugs to complete the burn faster.

Is it OK to change spark plugs yourself?

If you’re not comfortable with that, take your vehicle to a pro. But if your engine affords easy access to the rear bank, you can probably do the job yourself.

5 Signs You Need New Spark Plugs

1. Engine Misfires. A misfiring engine is a big sign that one or more of your spark plugs are not firing properly.
2. Poor Gas Mileage. When spark plugs are working correctly, they burn fuel efficiently in your engine.
3. Trouble Starting.
4. Slow Acceleration.
5. Rough Idling.

Can I drive with a bad spark plug?

Ideally, you should replace them immediately. However, you can get by for a short while, as long as they aren’t misfiring. Poor spark keeps fuel from being burned inside the combustion chamber. This reduces power and fuel economy, and it makes it harder for the engine to idle.

What happens if you never change spark plugs?

The deposits that build up on the plugs can eventually cause them to misfire. When this happens, the unburned fuel in the cylinders can start to eat away at the cylinder walls. This can cause dangerous pressure levels to build up, and it can even lead to engine failure.
