What should be paid attention to when installing spark plugs?
1 Answers
Precautions for the disassembly and installation process of spark plug products: 1. Before removing the spark plug, it is necessary to select the correct spark plug model according to the vehicle model and engine; 2. During installation, ensure that gloves or hands are clean and tidy to prevent oil from adhering to the insulator surface of the spark plug, as oil can conduct electricity under high voltage; 3. Prevent mechanical impact during transportation and handling to avoid cracks or breakage of the ceramic body; 4. During installation, use a spark plug socket to slowly place the spark plug into the spark plug hole to avoid deformation of the side electrode, which would alter the spark plug electrode gap; 5. Tighten the spark plug with a torque wrench or according to relevant regulations; excessive installation torque or significant deviation between the spark plug socket axis and the spark plug axis can damage the ceramic insulator, leading to engine vibration, side electrode erosion, or central electrode ceramic body fracture; insufficient installation torque can cause gas leakage or overheating; 6. After completing the spark plug installation, ensure that the connection between the spark plug and the high-voltage wire or ignition coil is secure.
