Where Are Spark Plugs Located?

Spark plugs are usually located at the top of the cylinder head. Once they "spark," it will fire a mixture of fuel and air within your vehicle's engine. This process creates the combustion that powers your GM model.

When Should I Replace My Spark Plugs?

If you are wondering when you should replace your spark plugs, you're not alone. Down the road, you're going to have to change them Ð but the symptoms are easy to spot. Here are some signs that may indicate it's time for a replacement:

  • Your GM vehicle isn't starting
  • Decease in fuel economy
  • Vehicle is having a hard time accelerating
  • The Check Engine light is on
  • Engine misfires

Remember that broken spark plugs can damage your engine's cylinders. It's important to pay attention to the warning signs above and perform a vehicle inspection, if needed.
