Anyone know the cooling capacity of a Breakaway/Cummins. I all the other capacities in the doc but not on the cooling system. Just says 50% mixture.

For the curious, when choosing anti-freeze for you diesel engine I have alway used low silicate. It turns out the 5.9 does not require it although I think I still do.

Answering my own question as I drained and then put 5.5 gallons of coolant back in.
