I got a nasty lecture from the diesel mechanic at my dealer for putting the wrong coolant in. I told him I have never lifted the hood of my truck and they must have done it as they are the only dealer that works on my truck.
He wouldn't believe me, because they would NEVER do something like that.
They either did it, or the factory did it. Still a mystery.
