Engine Coolant
Good morning to all. I have a 400 HP Cummins engine. What type and brand of coolant should I use?

Stop. There are two very different questions here:
IF your question is: "I am changing coolant, what do you recommend", I agree, one of the new-generation OAT-based coolants is the way I would go. If Cummins, would go with their house brand which is Fleetguard ES Complet OAT. If Cat, Caterpillar ELC.
IF you question is what to I top off my present system with, you need to check with your chassis maker (Freightliner I suspect). BUT, if this is OE coolant, you are way over-due to change it, as you do not have one of the long-life coolants from the factory.
