Ford Super Duty trucks are built to work hard and that also means taking care of them to make sure they continue to work hard is essential. On the dash of your Super Duty there are a number of warning lights that when indicate issues with your truck's mechanics. The Coolant Additive Light is not one of them. When your Coolant Additive Light comes on, contact our Ford Expert team at Sherwood Ford.
The Check Coolant Additive Light comes on every 600 hours to remind you to check the coolant levels. While this does not indicate a problem, it does mean you should bring your Super Duty in to a certified Ford Service Center for a Coolant Check. DO NOT just add more coolant to the system! This may do more harm than good. To ensure the proper service of your Super Duty, schedule an appointment with our team.
