How often should the spark plugs of a CCTSI engine be replaced?
1 Answers
CCTSI engine spark plugs should be replaced every 20,000 kilometers. The original 2.0T engine uses NGK PFR7S8EG spark plugs. The steps for replacing spark plugs are as follows: 1. Prepare a complete set of disassembly tools. 2. Remove the wiring plug on the ignition coil and the bolts on the ignition coil, then pull out the ignition coil. 3. After removing these, the exposed spark plugs can be seen, and a socket can be used to remove the spark plugs. (Note: The angle between the spark plug and the wrench should be vertical; an incorrect angle may cause thread stripping.) 4. Install the new spark plugs. Remember to slide them slowly along the inner wall to avoid collisions that could affect the spark plug's ignition gap. Methods for cleaning carbon deposits from spark plugs: 1. Carburetor cleaner: Place some cleaner in a container, soak the spark plugs for about 20 minutes, and gently scrub the spark plug heads with a brush to remove carbon deposits. 2. White vinegar cleaning: The method is the same as using carburetor cleaner, but it is quicker and more convenient. The white vinegar method should not be used frequently, as its corrosiveness can affect the spark plugs. After use, remember to rinse off any residual white vinegar from the surface.
