I keep getting the check coolant notice so I ordered up the kit and tested; the RA test indicates the orange caped vial (brown), the contamination test is in the middle more pass than fail. What should I do add vc12 or assume its a bad sensor and take it to the dealer? Do I need to test both cooling systems? mileage 13500
I can't help you on what to do but what kit did you order? I ignored mine the first time it came up at around 15000 but it just started coming up again. At almost 30,000 miles.
I ordered the Acustrip kit for Powerstrokes from diesel-filters. com. I would ignore the check coolant message but it comes up everytime I start the truck and stays on until I push ok.
Both systems tested the same
You have to go into the menu and reset the message. It isn't a sensor telling you your coolant is bad. It is just a reminder that the computer puts out telling you it's time to test it. If you just acknowledge it by pressing "ok", it will continue to pop up each time you start the truck.
Yes both cooling systems from the bottom of each radiator per the manual, or just reset and run the risk.
If you are sure no one ever added anything to either tank you are probably fine at both 15 and 30k. Not so at 45k+ - you need to test!
No sensors, just time and mileage turn on the notification.

Mine came up @ 60k mi. I went into the dealer to ask about checking it and the service manager just told me to clear it. In all the tests they had done they never had one fail if it hadn't exceeded the coolant replacement interval.
My personal opinion, which isn't based on anything other than observations, this ninny to check it was put in, because the previous generation powerstrokes (6.O and 6.4) had coolant issues. The 6.7 uses a different coolant which isn't susceptible to same issues the previous engines were designed to use. And the 6.7s have a much different Instrument Cluster and computers and such than the last generations did, so it's an easy thing to program. Dealers like it, because it generates A "you need to go in to see them" event.
