  Q: What tools and steps are necessary for replacing spark plugs on Volkswagen Golf SportWagen?

  A:

  The spark plugs are found in the cylinder head and the equipment to change them usually consists of a spark plug socket that will fit to a ratchet, different extensions and a feeler gauge to measure and adjust the spark plug gap. A torque wrench is advised in tightening the plugs properly particularly because such engines are made of aluminum in the cylinder head. Before proceeding, it is recommended to buy new spark plugs in advance and seat them to the appropriate gap and replace them one at a time, making sure that the right type is purchased to fit the particular engine. Meanwhile, the engine must be in full cool before the removal of any plugs, and the new plugs can be inspected also the gaps should be checked. The gap can be checked by putting the relevant thickness gauge between the electrodes, and cracks in the body of the spark plug have to be recorded, and broken plugs cannot be utilized. In order to protect the paint, wrap up the fender with fender cover or a blanket. There is one centrally located spark plug in each of the cylinders, and the ignition coils are mounted directly above the spark plug; it is necessary to remove the ignition coils beforehand. Provided that there is compressed air used, it is recommended to blow out any dust surrounding the spark plug to avoid debris making its way to the cylinder. The spark plug can be removed by putting socket over it and turning it counter clockwise. A comparison between the old spark plug and a chart may give information regarding the engine running status. The likelihood of the threads of the new spark plugs seizing in the aluminum head can be prevented by lightly applying an anti-seize compound on the threads. To prevent the cross threading during the time of installation, a piece of rubber hose can also be attached to the end of the spark plug that would act as a guide and it would not damage the threads. Install and screw the spark plug to the correct torque after which the rest of the plugs should be installed.
