relates to a vehicle: mounted EA211 engine models.
the contents of failure: When the EA211 1.4T, 1.2T engine spark plug replacement and maintenance, as required be sure, using a torque wrench with a standardized mounting new spark plugs spark plug wrench, the tightening torque of 22 N · m.
Procedure:
(1) after an ignition coil puller -T10530- -CT10530- or disassembly of the ignition coil, remove dust and foreign matter at the plug hole from falling into the cylinder.
(2) When removing plug, use a spark plug wrench.
(3) when installing the spark plug, should use a spark plug wrench vertically carefully spark plug pre-screwed into the plug hole, and then using a torque wrench (5 ~ 60 N · m) tightened to 22 N · m.
The spark plug removably irregularities resulting consequences:
The disassembly operation when the spark plug is not standardized, the installation tightening torque is too large, may result in the tightening effect between the housing and the ceramic body of the spark plug disappear. When the engine continues to run, resulting in the further loosening of the spark plug assembly, the center electrode even fall into the combustion chamber, resulting in serious damage to the engine (1, 2).
