TOPPING HE NGINE
Idle the engine a few minutes before routine shutdown. After full load operation, idle the engine three to five minutes before shutting
it down. This idle period will allow the lubricating oil and coolant to carry excess heat away from the combustion chamber, bearings, internal
components, and turbocharger. This is especially important for turbocharged, charge air-cooled engines. Refer to the following chart for proper
engine shutdown:
