CAUTION
Do not remove carbon or dirt buildup
from the compressor or turbine impel-
lers. The turbocharger must be disas-
sembled to thoroughly clean the
impellers. Even small deposits remaining
on the blades unbalance the impeller
and damage the turbocharger.

turbocharger must be cleaned Notify direct

leaks are caused by blocked air intake ducts
or damaged oil seals If the air filter and in-
take ducts are not blocked, the turbocharger
oil seals must be replaced Notify direct
