Ideal Temperatures for Cummins Engines

Looks like she just got of off a international jet (jet fuel basically diesel) flight. When she starts rowing her ass across the Atlantic then maybe I’ll listen to her speech.

Hello All, I always hear/see people talking about ideal temperatures for various systems of a Ram truck. Now as a first time diesel owner I would rely on temperatures on the gauges. Red means either slow down or stop and thats about it. I never really paid attention to the exact temperature of the gauge. If it got to red, be careful or the truck will tell you (per the gauges or notification). Is there anything the truck will NOT tell me that I should always keep an eye on? This goes for all systems of a Ram truck 2500-3500, such as engine, coolant, transmission, etc. What are your thoughts?

You need to stop well before it gets in the red, diesels are very very expensive to rebuild.. you should always look at your gauges
