Turbo Cool Down (Idle down) Before shut down

[ToolManTimTaylor]

Many times it's not done but here's that good ol' excerpt from the D/C Ram Owners manual:

Driving Condition/Load /Turbo Temp/Idle time before shut down.

Stop And Go......./Empty/.......Cool......./ Less Than 1 Minute

Stop And Go......./Medium/................../ One Minute

Highway............./Medium/....Warm....../ Two Minutes

City Traffic........../..MAX../..................../ Three Minutes

Highway............/..MAX../..................../ Four Minutes

Uphill................/..MAX../........HOT......./ Five or more

And obviously if you have a pyrometer you can safely monitor your shutdown temps until 350* (Rule O Thumb) or less is reached.
