Stopping The Engine

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 impor-

tant for turbocharged, charge air-cooled engines.
