Stopping the Engine

Stopping the Engine - Ops

Stop an engine under normal operating conditions as follows:

Notice: 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.
  1. Reduce engine speed to idle and put all shift levers in the neutral position.
  2. 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.
  3. 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.
