Your car’s engine is its heart—converting fuel into the power that moves your vehicle. But like anything mechanical, engine components wear out over time. Let’s take a quick look at how it works and which parts you may need to replace.

How the Engine Works

• Pulls in air and fuel
• Ignites the mixture (creating small explosions)
• Drives pistons up and down
• Turns that motion into power to spin your wheels

The engine is a finely tuned system—so even one worn-out part can affect performance or cause damage.

Common Engine Parts That Need Replacement

1. Spark Plugs
   Ignite the fuel/air mixture. Worn plugs = misfires, rough idling, poor mileage.
2. Timing Belt or Chain
   Keeps engine components moving in sync. Failure can cause major engine damage—replace as recommended.
3. Ignition Coils
   Send power to spark plugs. Faulty coils = misfires or starting issues.
4. Sensors (O2, MAF, etc.)
   Help your engine run efficiently. Bad sensors trigger the check engine light and reduce performance.

When to Replace Engine Parts

• Loss of power or rough starts
• Engine knocking or strange noises
• Check engine light staying on
