Kia Spectra engines are available in 1.5, 1.6, 1.8 and 2.0 liter sizes. You should replace the spark plugs in your Spectra every 30,000 miles to ensure your car starts and runs correctly. In some Kia Spectras, the spark plugs are located beneath a black cover on top of the engine and you'll need to remove four screws on this cover to reveal the spark plugs before you can replace them.
Instructions
1. Raise the hood and locate the battery. Disconnect the negative battery cable. Allow the engine to cool before attempting this process. Depending on the climate, it may take 30 minutes or more to cool the engine.
2. Find the spark plug cables on the Kia Spectra engine of either a four- or six-cylinder variety. The number of cylinders indicates the number of spark plug cables on the engine.
3. Turn the cables by the boot, or cover, that connects to the engine or directly to the spark plug. Disconnect one cable and complete the replacement process before removing the other cables to ensure the cables don't cross. Pull back on the cable to reveal the spark plug.
4. Remove the spark plug from the cylinder well with the socket. The extender may not be needed for 4-cylinder engines. Turn the socket in a counter-clockwise motion to unscrew the plug and remove it from the cylinder block.
5. Use the applicator supplied with the anti-seize to spread the compound over the threads of the new spark plug. This compound allows for easy removal when you need to check or replace the spark plugs.
6. Screw the spark plug into the cylinder well by hand. The spark plug needs to be tight in the well but may have to be loosened after the tension test finishes.
7. Test the torque of the spark plug with the tension tester tool. Normally the spark plugs on a Kia Spectra need 18 to 22 ft-lbs torque. Check the Spectra model's owner's manual or the manufacturer's package because some premium or performance spark plugs use different torques.
8. Reconnect the spark plug wire and turn it to lock it in place. Continue replacing the rest of the spark plugs. Reconnect the battery cable after you replace all the spark plugs.
Tips Warnings
Replacing the spark plugs for all Kia Spectra engine sizes is a process that takes about 30 minutes to 1 hour to complete.
Replace one spark plug at a time to prevent damaging the engine.
