If any of the following occur, shut down the engine immediately.
-
The oil pressure swings back and forth or falls sharply.
-
Engine power and rpm fall even though the throttle pedal remains steady.
-
The exhaust pipe gives off heavy smoke.
-
The coolant and/or oil temperature climb abnormally.
-
Abnormal sounds suddenly occur in the engine or turbocharger.
- With the vehicle stopped, apply the parking brakes, and place the transmission in neutral.
- Allow the engine to run at idle for four to five minutes. This allows the engine to cool and the turbocharger to slow down.
- Turn off the ignition switch and shut down the engine.
Important: Bearings and seals in the turbocharger are subjected to the high heat of combustion exhaust gases. While the engine is running, this heat is carried away by oil circulation, but if the engine is stopped suddenly, the turbocharger temperature may rise as much as 115°F (63°C).
Caution: Except in emergency, do not shut down the MBE4000 engine when the coolant temperature is above 194°F (90°C). To do so could damage the engine.
Caution: Idle the engine one to two minutes before shutting it down, if this can be done without damage to the engine. After hard operation, shutting down the engine without idling may cause damage to the turbocharger.
