Stopping the Engine
Stopping the Engine - Ops
Stop an engine under normal operating conditions as follows:
Note: Do not stop a turbocharged engine
immediately after a high-speed operation. Allow a sufficient cool-down
period of about five minutes to prevent the turbocharger from continuing
to turn without an oil supply to the bearings or damage can result.
- Reduce engine speed to idle and put all shift levers in the neutral position.
- Allow
the engine to run between idle and 1000 rpm with no load for five
minutes. This allows the engine to cool and permits the turbocharger
to slow down. After five minutes, shut down the engine.Note: Cool-down idling needs to take place after pulling off an interstate. When finding a parking spot or backing into a dock, immediate shutdown should be avoided. Shutting the engine off immediately retains more block heat than if the engine runs at idle for five minutes.
