Injectors

•
Solenoid valve-type injectors with lower power consumption and better response have
been introduced.
1 From common rail
2 Connector
NOTE: Since the size of the injector connector is relatively big compared to the diameter of
the injector head, there might be an interference between the connector and the
injector seal during removal and installation of the cylinder head cover. In order to
prevent any damage to the seal, wrap vinyl tape around the injector connector
covering the connector edges.
•
In addition, the leak-off lines of the injectors are located under the cylinder head cover.
As a result, the total leak-off amount of the injectors must be measured and compared to
the values of a known good vehicle in order to detect a leaking solenoid valve.
NOTE: Always replace the gaskets of the injector leak-off lines when removing them. As the
leak-off lines are located under the cylinder head cover, fuel leaking from the lines
can contaminate the engine oil. This results in engine oil dilution and hence in engine
damage.
