Precautions:
-Due to the concave position of the spark plug, it is necessary to first blow out the dust from the new spark plug, otherwise the dust will fall into the cylinder. When unplugging the high-voltage wire, some cars have the high-voltage wire inserted very tightly, which requires slow shaking up, down, left, right, and left.
-Pay attention to placing the wrench as straight as possible.
-When disassembling spark plugs, one should be disassembled and installed one by one. After removing the first spark plug, a new one should be installed.
-When installing a new spark plug, a layer of lubricating oil can be applied to the surface.
-A new spark plug should be slowly inserted and should not be hasty. To tighten the spark plug with a socket wrench, follow the prescribed torque distance.
