Tom,
I haven't added anything to the radiator yet. Yesterday, I spoke to a DD service manager and he said to add pure anti-freeze (Power Cool) to the radiator. Then use the test strips to test for the correct level of nitrates (color coding). So I guess I'll just do that.
I drain/change anti-freeze every 3 years and have been using the Power Cool with good results. It is what Newell and DD recommend. Kind of difficult to go against that.
