How do you change spark plugs on a Chevy HHR?

Changing Spark Plugs on a Chevy HHR
To change the spark plugs on a Chevy HHR, follow these steps:
1. Gather the necessary tools: You will need a 5/8 socket, 8mm socket, 10mm socket, and a wrench.
2. Locate the spark plugs: The Chevy HHR uses a modern electrical distributorless ignition system, which means it does not have spark plug wires. Instead, it has a coil pack that delivers controlled electrical power to fire the spark plugs.
3. Remove the coil pack: Start by disconnecting the negative battery cable. Then, locate the coil pack, which is usually located on top of the engine. Remove the electrical connectors and bolts holding the coil pack in place. Carefully lift the coil pack off the spark plugs.
4. Remove the spark plugs: Use a 5/8 socket and a wrench to remove the spark plugs from the engine. Turn the socket counterclockwise to loosen and remove the spark plugs. Be careful not to damage the threads or the porcelain insulator on the spark plugs.
5. Inspect the spark plugs: Once the spark plugs are removed, inspect them for any signs of wear or damage. If the spark plugs are worn or damaged, it is recommended to replace them.
6. Install the new spark plugs: Install the new spark plugs by hand, making sure they are threaded correctly. Use a torque wrench to tighten the spark plugs to the manufacturer’s specifications. Be careful not to overtighten the spark plugs, as this can cause damage.
7. Reinstall the coil pack: Place the coil pack back onto the spark plugs and secure it with the bolts. Reconnect the electrical connectors to the coil pack. Finally, reconnect the negative battery cable.
It is important to note that the recommended spark plug life for the Chevy HHR is 100,000 miles. However, if you prefer to change them sooner, it won’t cause any harm.
Remember to consult your vehicle’s manual for specific instructions and torque specifications for your Chevy HHR model.
