NGINE
After full load operation, idle the engine for a few minutes before shutting it down. This idle period will allow the lubricating oil and coolant to carry excess heat
away from the turbocharger. Refer to the following chart for proper engine shutdown.
NOTE:
Under certain conditions the engine Stop/Start functionality may be temporarily disabled and the engine fan will run after the engine is turned off to protect the
engine. These conditions are under high load and high temperature conditions.
