Are you ready to tackle a car maintenance task yourself? Changing spark plugs on your 2017 Kia Sorento might seem daunting, but with the right tools and guidance, it’s a manageable DIY project. This comprehensive guide will walk you through the process step-by-step, empowering you to save money and gain valuable mechanical knowledge.
Why Change Spark Plugs?
Spark plugs are essential components in your car’s engine, responsible for igniting the air-fuel mixture and powering the combustion process. Over time, spark plugs wear out, leading to decreased engine performance, rough idling, and even misfires. Replacing them ensures optimal engine efficiency and longevity.
Gather Your Tools and Supplies
Before you begin, make sure you have the necessary tools and materials:
- New spark plugs: Consult your owner’s manual or a reliable online resource to identify the correct spark plug type for your 2017 Kia Sorento.
- Socket wrench set: You’ll need a socket that matches the size of your spark plugs (usually 5/8 inch).
- Torque wrench: Essential for tightening the spark plugs to the manufacturer’s specifications.
- Ratchet: For turning the socket wrench.
- Extension: May be needed to reach the spark plugs.
- Spark plug gap tool: Used to adjust the gap of the new spark plugs if necessary.
- Gloves: Protect your hands from grease and dirt.
- Safety glasses: Shield your eyes from debris.
- Shop towels: For cleaning up spills and dirt.
- Optional: Spark plug boot puller: Makes removing the spark plug boots easier.
Safety First: Important Precautions
- Disconnect the battery: Always disconnect the negative terminal of your battery before working on the engine. This prevents electrical shocks and potential damage to your car’s electrical system.
- Work in a well-ventilated area: Engine fumes can be harmful, so ensure adequate ventilation.
- Use caution with hot components: The engine and exhaust manifold can be extremely hot after running, so allow sufficient time for cooling before working on the spark plugs.
Step-by-Step Guide to Changing Spark Plugs
Now that you’re prepared, follow these steps to change the spark plugs on your 2017 Kia Sorento:
1. Locate the Spark Plugs: Open the hood and locate the engine. The spark plugs are typically located on the top of the engine, near the valve cover. Refer to your owner’s manual or a repair manual for the precise location.
2. Remove the Spark Plug Wires: If your 2017 Sorento has spark plug wires, carefully disconnect them from the spark plugs. Use a spark plug boot puller if available to make removal easier.
3. Remove the Spark Plugs: Use your socket wrench and ratchet to loosen and remove the old spark plugs. Be careful not to cross-thread the socket.
4. Inspect the Spark Plugs: Examine the old spark plugs for signs of wear, such as excessive electrode wear, carbon buildup, or cracks. This information can help you diagnose any engine problems.
5. Install the New Spark Plugs: Before installing the new spark plugs, check their gap using a spark plug gap tool. Refer to your owner’s manual or the spark plug packaging for the recommended gap. Carefully thread the new spark plugs into the cylinder head.
6. Tighten the Spark Plugs: Use your torque wrench to tighten the spark plugs to the specified torque. Overtightening can damage the spark plugs or cylinder head, while undertightening can cause leaks or loosening.
7. Reconnect the Spark Plug Wires: If your Sorento has spark plug wires, reconnect them to the new spark plugs, ensuring a secure connection.
8. Reconnect the Battery: Once all the spark plugs are installed and the wires are connected, reconnect the negative terminal of the battery.
9. Start the Engine: Start the engine and listen for any unusual noises or rough running. If everything seems normal, you’ve successfully replaced your spark plugs.
Troubleshooting Tips
If you encounter any issues during the process, here are some troubleshooting tips:
- Difficulty removing spark plugs: If the spark plugs are difficult to remove, try using a penetrating oil to loosen them.
