1989 7.3 idi no turbo. F350 DRW SC. Newly rebuilt engine. I had a lot of oil in the water jacket because I screwed up the reassembly of the oil cooler by nicking an o ring. With the water jacket cleaned out, I bought Fleet Charge antifreeze. The bottle says meets or exdeeds the requirement of the following specifications:. . . . .tmc astm cummins cat, detroit, freightliner and goes on to list Navistar B1. The coolant is pink? I am used to ethylene glycol which is green. The question is: Should I put it in or get the green antifreeze and add the SCA myself. I do not know what the spec is for Navistar B1...can anyone clarify this for me?
