Hello, I just see a fluid by the front passenger tire leak when the diesel is running and ac is on.There was fluid up by both aluminum lines going into a plastic canister in the engine compartment on the passenger side.I couldn't find any cracks in the hoses or aluminum lines..The plastic canister I believe is (AC ACCUMULATOR ) did have a hiss of air when I shut the truck off. I can't see where the clear liquid is coming from. Any ideas?? Just started to leak by the front passenger tire.

 

The "leak" as you call it sounds to me that it is condensation. Nothing to worry about and is normal in humid areas.
The "hiss" you hear when you shut it off is the pressurized refrigerant going through the orifice tube. The noise stops because the pressures on both sides of the orifice tube equalize, eliminating flow.

 

There is a drain from the a/c evaporator coil that allows water that condenses on the outside of the coil to be routed outside the truck. During the summer all vehicles with a/c will have water dripping out of this tube in areas with higher humidity. Not so much in Arizona, etc.

 

Hello, it looks like condensation on the aluminum lines and the rubber hoses. The engine fan was blowing the condensation all over the place. Just never saw that before. It was hot and humid out at the time. Like I said, I just never seen water on those hoses before.
