Question - I have water dripping after a long drive over the rear most part of the front driveshaft. It is not coolant, it is clear. Is it an A/C Drain? Anything to be concerened about? I don't think I had the A/C on but had the cabin temp at 66 with floor vent. outside temp was mid 40's.

My coolant resovoir was also a little low when I checked it before my roadtrip. Filled to the cold line before I left and it hasn't moved after sitting for several hours so unsure about that. Changed the oil today and took a sample to send to Blackstone just to make sure I have no coolant/headgasket leak.

Any thoughts?

 

Sounds like your a/c drain is clogged.
There are 2 of them, one for each side.
Crawl under the truck and on either side of the bell housing you will see the nipples that cover the ends of the drains.
Squeeze them until nothing comes out.
Do this at every oil change.

If you have your HVAC set to "auto" then it will turn your a/c on or off depending on what it thinks you need.
Set it to "eco" (economy) mode to make sure it is off.
