Turbocharger: Testing and Inspection

Turbocharger

INSPECTION

1. WASTE GATE ACTUATOR
1. Remove the collector cover.
2. Remove the intercooler.
3. Remove the turbocharger upper cover.






4. Remove the boost hose (B) from the waste gate actuator (A) of the turbocharger, and connect the Mighty Vac to the waste gate actuator (A).






5. Pressurize slowly with the Mighty Vac, and check the pressure when the control rod stroke (D) becomes 1 mm (0.04 in). If it is not within the standard, replace the turbocharger assembly.

CAUTION: Do not pressurize over 56.0 kPa (0.57 kgf/sq.cm, 8.12 psi) to prevent damaging the waste gate actuator.

Operating pressure (control rod stroke 1 mm (0.04 in)): Standard 44.0 - 46.6 kPa (0.45 - 0.48 kgf/sq.cm, 6.38 - 6.76 psi)

6. 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)

2. OTHER INSPECTIONS
1. Check that the turbocharger and pipe have no deformation, cracks or other damages.
2. Check that the hose and intake duct have no cracks, damage or loose part.
3. Check that there are no oil leaks or water leaks from the pipe attachment section.
