Info Warning
Driving home yesterday, I get a message/warning on my instrument display saying, "check coolant additive". Which coolant is it referring to ? The main coolant or the inter cooler/turbo coolant ? 2012 w/ 6.7 130,000 miles. FYI, there is only 7000 miles on the main/primary coolant since a COMPLETE flush. Have the new yellow Motocraft coolant. Did not change the turbo side coolant yet because it looked so clean. It has a pinkish-red color in it. I have only put on maybe 9000 miles on it since I bought it. So I don't know how old it is.
So every time I start the truck, this warning is displayed.
What to do.

Back in the early 6.7L engines. The message would pop up every so often wanting you to test the coolant. If it failed the test you needed to add the Coolant rejuvinator. You could add it up to 3 times before needing to replace coolant.
I would just clear the message.
