The reservoir in the 05 need to be refilled (never done before) but I wonder why. Some time ago I posted about this situation since I noticed there was white dripping marks around the top of the coolant reservoir, now I can see clearly that is needs to be refilled, I wonder what is causing this since the truck has not towed anything in the past few weeks. I drive it in traffic some times with the a/c ON but nothing else. Btw it has an auto tranny.
Thank You.
