4. Pressurize with mityvac, measure the pressure when control rod stroke reaches 2 mm (0.08 in). If it is not within the standard, replace the turbocharger assembly.
CAUTION:
Do not pressurize to 89.8 kPa (0.92 kgf/cm2, 13.0 psi) or more because doing so will damage the wastegate actuator.
Operating pressure (control rod stroke 2 mm (0.08 in)):
Standard value
74.6 — 80.8 kPa (0.76 — 0.82 kgf/cm2, 10.8 — 11.7 psi)
5. After inspection, install the related parts in the reverse order of removal.
Tightening torque:
7.5 N·m (0.8 kgf-m, 5.5 ft-lb)
• Check the pipe installation portion for the oil and water leakage.
• Check for cracks or loose connections.
