INSTALLATION
INSTRUCTIONS
1.
Allow the engine to cool so that
coolant pressure is minimal. Remove
the plastic engine cover from the top
of the engine (see Figure 1). Remove
the three (3) mounting bolts of the
turbine heatshield and remove the
heatshield to allow access to the
actuator bracket bolts.
2.
Remove the E-clip from the pin
through the wastegate arm. Remove
the top turbocharger coolant inlet
hose with a #55 torx wrench (see
Figure 2). Be sure to retain the
gaskets and torx bolt for
reinstallation, but the E-clip may be
discarded as it will not be reused.
3.
Remove the actuator air hose at
the compressor outlet. Pressurize the
inlet air hose with a regulated supply
of air pressure to relieve tension on
the actuator pin. Remove the pin
from wastegate arm. Remove the two
actuator bracket bolts from the
compressor housing with a 12-mm
socket and retain for reinstallation.
4.
Remove the factory actuator,
mounting bracket and actuator
pressure hose from the engine.
Discard the factory mounting nuts
and actuator pressure hose, as they
will not be reused.
5.
Hold the Banks actuator bracket
up against the compressor housing in
the factory location. Turn the rod end
link on the threaded shaft until the
pin can be inserted into the
wastegate arm with the wastegate in
