Turbocharger: Testing and Inspection
TurbochargerINSPECTION
1. WASTE GATE ACTUATOR
1. Remove the intercooler.
2. Remove the turbocharger upper cover.
3. Remove the boost hose (B) from the waste gate actuator (A) of the turbo charger, and connect the Mighty Vac to the waste gate actuator (A).
4. Pressurize slowly with the Mighty Vac, and measure the pressure when the control rod stroke (D) becomes 2 mm (0.08 in). If it is not within the standard, replace the turbocharger assembly.
CAUTION: Do not pressurize over 89.8 kPa (0.92 kgf/cm2, 13.0 psi) to prevent damaging the waste gate actuator.
Control pressure (Control rod stroke 2 mm (0.08 in)):
Standard value 74.6 - 80.8 kPa (0.76 - 0.82 kgf/sq.cm, 10.8 - 11.7 psi)
5. After inspection, install the related parts in the reverse order of removal.
2. OIL PIPE AND WATER PIPE
- Check that there are no oil leaks or water leaks from the pipe attachment section.
- Check for cracks or loose connections.
