Wagon 4WD F4-1781cc 1.8L Turbo (1984)
EXAMPLES Of FAILED TURBOCHARGERS
Inadequate lubrication supplied to the turbocharger will cause damage to the turbine center shaft bearing. This will cause radial movement of the shaft
permitting the compressor impellers to come in contact with the housing.
Before replacing a damaged turbocharger, review the customer's maintenance history. If there is evidence that the engine was not properly maintained,
follow the Engine Oil System Flush instructions prior to replacing the turbocharger to avoid a secondary failure.
