Drainage tube?

[SweetDave]

Is anyone aware what this provides drainage for? My A/C has not been in nor is it raining. Maybe the oil or turbo coolers?

Maybe bed or roof channels?

That stands to reason, but it was dripping after I stopped (I’ve noticed it before) in the same way that A/C condensation drips after you stop, but I’ve not had A/C on nor was there any rain that would account for any other drainage. Has to be an internal cooling system?

Oh it's engine bay? Maybe water drainage from the channel at the bottom of the windshield?

I’ve always found my vehicles to run ac automatically that’s usually how you keep your windshield clear and fog free, were you running defrost?

Is that on the left, right, front? I will take a look to see if mine has anything coming out and try to figure out where it's coming from as well.

I'm sure you've run defrost. AC is on by default. If it's water, I wouldn't be too concerned

I just found it in my car only on the passenger side. There is a plug on the other side with nothing going through it. I don’t see anything the color of that tube in the engine bay which makes me think it’s a drainage tube possibly coming from within the car. Time to look and see if shop manuals are available for these trucks yet.
