Stopping the engine immediately after it has been working under load can result in overheating and accelerated wear of the engine components.If the engine has been operating at high rpm and/or high loads, run at low idle for at least three minutes to reduce and stabilize internal engine temperature before stopping the engine.Avoiding hot engine shutdowns will maximize turbocharger shaft and bearing life.
In order to allow the engine to cool gradually, operate the engine at low idle for three minutes.
