FLUID RECOMMENDATIONS



All Previa superchargers use a special supercharger oil (08885-80108) or equivalent.

  2.  
  3. On the 4WD models, remove the left front suspension support member and the shift cable stay.

  5. Remove the dipstick again and look at the oil level on the end.
  6.  
  7. The oil level should be between the L and F marks on the dipstick.
  8.  
  9. If the level is low, check for leakage and Air Control Valve (ACV), and add oil up to the F mark.

The supercharger could be damaged if it is overfilled or the oil level is low.

  1. On the 4WD models, reinstall the left front suspension support member and shift cable assembly.
  2.  

DRAIN & REFILL



Inspect the supercharger oil every 30,000 miles (48,000 km). Toyota does not have an interval to drain and refill the system. If necessary, remove the magnetic plug under the rear cover and drain the oil. Insert the plug with gasket and using a syringe and vinyl tube, fill the system with supercharger oil.
