2018 Coolant leaks when cold
Anyone else have big coolant leaks when its cold on their 2018+? Seems like many are leaking when it's -25C or colder. Mine started with this past cold snap, two coolant hoses that go to the cooler which is low slung between the engine and trans pans. I'm not sure exactly what this cooler is for... I'm assuming it's for the transmission fluid and has coolant go through it to cool it. But mine will leak a lot if its parked out in the cold. Put it in the heated garage and it will not leak a drop... Of course the hoses are back ordered and because so many are having this issue there is no current eta on parts, I've been told to just keep topping up the coolant degas as needed.

I do know the old screw-type hose clamps would leak when cold; the rubber would contract under the set clamp, and leak. Everything factory is a constant-tension clamp, and they do exactly like it sounds. Something sounds like its contracting under the extreme cold condition. I know those are frustrating to chase.

Appointment made for repairs coming up.
The mechanic even said the leak will probably stop once the temperatures warm-up, but seeing it's under warranty they are going to fix it at no cost. I believe he stated there are issues with the style of clamps they are using and not causing a tight seal in frigid temps.
The mechanic just topped it up until I can get in Feb 7 for repair and told me to keep an eye on the coolant level.
Hope this helps

Well......
The truck is at the dealership for the coolant leak. Just got a call and the upper rad hose needs to be replaced.
Glad I took it in and I have a loaner for the next few days until the part arrives.
On a good note, they are also doing the freezing door lock TSB "FIX".
