STARTING AND OPERATING 263 Stopping The Engine Idle the engine a few minutes before routine shutdown. After full load operation, idle the engine 3 to 5 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, like your Turbo Ram. Driving Condition Stop and Go Stop and Go Highway Speeds Load Empty Medium Medium Idle Time Turbo(min.)
