How often should the spark plugs be replaced in a Volkswagen 1.4T vehicle?
1 Answers
Volkswagen 1.4T spark plugs should be replaced every 20,000 kilometers. Additional information is as follows: How spark plugs work: Spark plugs consist of an insulator and a metal shell. The metal shell is threaded and screwed into the engine cylinder. Inside the metal shell, there is a central electrode insulated from the shell by insulating material. The top of the central electrode has a terminal nut connected to the high-voltage wire from the distributor. A ground electrode is welded below the metal shell, with a small gap between the central and ground electrodes. A pulsed high voltage arcs across this gap, creating a spark that ignites the air-fuel mixture to perform work. Methods for cleaning carbon deposits from spark plugs: Carburetor cleaner: Place an appropriate amount of carburetor cleaner in a container and soak the spark plug for about 30 minutes. Then, gently scrub the spark plug's tip with a soft-bristled brush to remove carbon deposits. White vinegar cleaning: This method is similar to using carburetor cleaner but is simpler and more practical. However, white vinegar should not be used frequently as its corrosive properties can affect the spark plug. After removing carbon deposits, ensure any residual vinegar is thoroughly cleaned off.
