    2016 RAM 2500 6.7L - Low Coolant Message

    An intermittent low coolant light illuminated while I was driving in cold weather; now it persists.

    I checked the coolant reservoir, and it's full, I topped it off with ES Compleat and Fleetcool EX, and still, the light is on.

    I replaced the temperature sensor on the driver's side mirror.

    Any thoughts on what is causing the low coolant message?

    Welcome to the forum.

    The coolant sensor isn’t located in your mirror.

    The sensor in your mirror is for the outside ambient air temperature.

    Have you had any service done to your coolant system?

    If so, it could be a trapped air pocket causing your issue.

    Hopefully, someone else can chime in that has had this issue before, friend.

    I also agree that it is more then likely trapped coolant.

    It’s not easy burping these things like it used to be.

    Sometimes it takes a little time and a little bit of a mess to burp them.

    I had this message, the coolant level sensor is located under the reservoir.

    I had to take the passenger wheel well cover off.

    Unfortunately, I changed out the sensor and still got the code.

    Come to find out, the connector going to the coolant sensor wasn't making a tight connection, so I shoved a wire into the connector and taped it.

    Now the message is off, LOL.

    I had a coolant flush a year ago, and I'll try the coolant sensor at the bottom of the tank.

    Hopefully, it's just a sensor or loose connection.
