Turbocharger “Cool Down”
NOTE: Letting the engine idle after extended operation
allows the turbine housing to cool to normal operating
temperature.
The following chart should be used as a guide in deter-
mining the amount of engine idle time required to
sufficiently cool down the turbocharger before shut
down, depending upon the type of driving and the
amount of cargo.
