TURBO CHARGER SYSTEM
10-3
The vehicle owner should be encouraged to observe the fol-
lowing precautions to ensure maximum turbocharger ser-
vice life.
PREVENTIVE MAINTENANCE
• Operate the engine over the idling speed only after normal engine
oil pressure has been established. Forcing the turbocharger to op-
erate before the bearings are adequately lubricated creates unnec-
essary friction.
• Take steps to reduce temperature and speeds from their maximum
before shutting down the engine.
The engine equipped with turbocharger develops much more heats
than a normal engine, so when the engine is stopped abruptly, the
oil in the bearings may evaporate due to heats and can be stuck.
• Use only the specified engine oil and observe inspection and re-
placement intervals.
CAUTION
• At low ambient temperature, or when ever the vehicle has not
been used for a long period, normal engine oil pressure and flow
is affected. Under these conditions the engine should be started
and allowed to idle for a few minutes before operating at higher
rpm.
• Avoid long periods of engine idling. The combination of low-pres-
sures in the turbine and compressor may allow oil to seep past
the seal into the turbine or the compressor.
• The turbocharger may need to be pre-oiled after oil change or
any service that involves oil draining. Crank the engine a few
times before allowing start, then start the engine and allow it to
idle for a period to establish full oil circulation and pressure be-
fore operating at higher rpm.
