I had read that. 2073 and 2074 have a lot of additive in them. I am assuming Tony recommends to start with those if you put in coolant with no additive in them. If you fill with pre-charged coolant such as the Fleetguard ES Compleat, Peak Fleet Charge or Prestone Command, then use a blank filter WF2077. Then test the coolant a year later to see what filter to change to.January 10, 2017 at 8:57 pm#14364

JBB,
What I say here is based on real field experience (not the “book”) with this engine since it released in the mid to late 80’s………..
The 6CTA 8.3 base engine has a modern mid-stop liner design, and obviously, is also made from superior quality materials, plus has a coolant flow design that when all put together, seems to make this engine very tolerant of something less then a “school book” coolant make up..
So I say this————Use any brand name 50-50 EG coolant, use a WF2073 or WF 2074 filter when you change, and then change the coolant every 3000-4000 hours or 5-7 yrs, which ever come first.. Go fishing and don’t worry about the rest..
