Waste gate operation
1. Remove the hose from the waste gate actuator.
2. Install the pressure gauge (general tool). Refer to the illustration.

1. W aste Gate Actuator
2. W aste Gate Hose
3. Pressure Gauge (General Tool)

3. Use the pressure gauge pump to apply pressure
(load) to the waste gate actuator (the engine must
be off).
4. Note the pressure at which the control rod moves 2 mm (0.078 in). This pressure must be within the
specified limit.

Control rod pressure range: kPa (mmHg / psi)
109 − 118 (818 − 885 / 16 − 17)

5. Inspect the hose for cracks and other damage.
Replace the hose if necessary.
6. Do not apply a pressure of more than 120 kPa (900 mmHg) to the waste gate actuator.

Installation
1. Put the gasket in to install the exhaust manifold.
