Wastegate: Adjustments
The wastegate turbocharger provides additional low speed boost without over-boost at high speeds. This increases low speed torque and better
driveability.
Wastegate Turbocharger
Proper adjustment of the wastegate assembly is critical to the operation of the wastegate turbocharger). The control rod is set at the factory and no
adjustment should be necessary, unless wastegate assembly is damaged.
CAUTION: DO NOT adjust the wastegate so that higher pressures are required to open the wastegate valve. The turbocharger speed will be
increased and can cause damage to the turbocharger and cause a loss of engine performance.
1. Disconnect signal line from wastegate actuator. The signal line may be installed with tamper-proof clamps. These can be discarded and replaced
with standard worm-gear clamps.
Wastegate And Dial Indicator
2. Connect regulated air pressure to the wastegate actuator. Install a dial indicator to measure the control rod movement. Apply 103 - 138 kPa (15 -
20 psi) to seat the components and take any slack out of the control rod. Release the air pressure and zero the dial indicator gauge.
3. Apply 193 kPa (28 psi) air pressure to the actuator. The control rod should move 0.33 - 1.33 mm (0.013 - 0.052 inch) total travel. If the rod travel
is out of limits, the wastegate linkage must be adjusted.
