How long should you let diesel engines idle to warm up?

Over 50 degrees-2 minutes, 0-50 degrees- 3 to 5 minutes, and below 0- 7 minutes. That is the basic standard of idle before driving. You do not need to idle it before shutting it down.

Are short runs hard on diesel engines?

Shorter trips do not allow the engine to warm up appropriately, and can cause carbon buildup. To avoid this, it is recommended 15-20 minutes of loaded running, and at least 1 hour of straight highway driving per month, to keep a truck in shape.
