How long does it take to change the car spark plug installation skills?
Now the newly -produced cars have a engine cover on the engine, which has the effect of beauty and heat insulation.Disassemble the engine cover before disassembling the spark plug.Of course, for the V -type engine located in the middle of the engine, an accessories such as the intake pipeline need to be removed.
1. To remove the spark plug, you must first pull out the ignition coil.Remove the thread insertion of the ignition coil and pull the bolts of the ignition coil, and you can pull out the ignition coil.
2. The ignition coil and the cylinder are sealed with rubber, and you need to use more force when you pull out.
3. Disassemble the spark plug to prepare a wrench, long rod and hexagonal sleeve.The spark plugs used in the car are generally disassembled with a 16mm hexagonal sleeve.
4. Magnetic hexagonal sleeve can bring out the sparkled spark when disassembling the spark plug.If the spark plug you use is not magnetic, it is recommended to plug a thicker double -sided glue in the sleeve, and you can bring out the sparkling spark plug together.
5. If possible, you can apply an appropriate amount of "threaded card prevention" on the new spark plug thread before installing the spark plug.When installing the spark plug, the spark plug should be fixed (magnetic sleeve or use double -sided glue) on the sleeve and then the spark plug back to the original place.It is forbidden to put the spark plug directly from the installation holes. The height gap may cause the side electrode deformation to cause the gap to become smaller, resulting in the early jump of fire affecting the smoothness of the engine.
6. If you use a torque wrench to tighten the spark plug torque, please follow the figure above.The spark plugs used in general cars are light metal, and the thread parameters are "M14x1.25".Generally, online shopping websites can find suitable models through models.Essence
7. In the absence of a torque wrench, the spark plugs can be pre -tightened according to the above figure.The pre -tightening angle of the plane base spark plug is 90 °, and the pre -tight angle of the cone -shaped base is 15 °.
