Tech Tips
If replacing the timing belt before the timing belt warning light comes on, (light comes on after 100000 km of driving), be sure to reset the timing belt counter of the speedometer to zero.
Note
When installing, clean up the seal surface of the injector, injection pipe, fuel inlet pipe, supply pump and common rail with clean light oil.
In case of having the common rail and/or injectors replaced, must replace injection pipes, too.
In case of having the supply pump and/or common rail replaced, must replace fuel inlet pipe, too.
