Hi everyone, I am at a stand still with my 2012 pathfinder. Just got it back from body shop after my wife hit a deer. It did some damage to the right front of vehicle.they ended up changing radiator, grill, front quarter panel and a bunch of other things. Ever since I got it back, my wife and I can smell antifreeze. Never had it before. It only has 48000 miles on it as well. I keep noticing the pressure tank on fender. It has what looks like a vent just below cap. Is there supposed to be a line on that? I have read where there is supposed to be a plug on it, but not sure. I put my finger at the end of it, and it's wet. I am thinking that is the smell. Please help, thanks. Jason
