I have run into the dreaded leaking Y pipe. The other day I could smell antifreeze when I parked the van. Popped the hood and sure enough, one of the Y pipes was leaking. I was surprised to find I have 2 of them in my 2013 T& C Touring 3.6L van. the one that was leaking was the one behind the real easy to see one. Luckily I had already bought one of the aluminum replacements and it took less than 1/2 hour to replace it the next morning. Next thing I did was order another Y pipe so I can replace the second one (before it starts leaking).
