Ism 450 dca

Looking for an opinion. I've got an ISM 450 and had the DCA checked at Cummins Mid-South, they said it was fine. Now I've got to change the antifreeze filter and found that they have DCA added in the filter. The question is - is too much DCA bad?

DCA is a range. The best way to keep the DCA in the correct range is to change the coolant filter annually. DCA is used up will time and Milage so if you change the coolant filter with one that has 4 units of DCA you should be fine. It's best if you keep the DCA within the recommended range but too high is not nearly as bad as too low. Buy a couple of test strips and do a test yourself and you will have a better understanding.

With an 2008 Newmar check your coolant it should be extended life coolant and not need any DCA added. My 2007 came with extended life coolant.
