So here's the deal on an 08 Dodge Grand Caravan
with the 3.6L, and others I'm sure, have this problem that is kind of hard to track down. When get off the highway and stop you'll smell burnt antifreeze. There's never an obvious leak or puddle and regular pressure testing doesn't seem to find the leak.You have to stop immediately when the smell happens and open the hood to find the problem. This plastic Y-pipe leaks.
hen it leaks the antifreeze hits the exhaust manifold and instantly evaporates. So you get the smell, but no other evidence.
ere's better look at the Y-pipe in question.
his pipe has broken on me twice now. This is the stupid part. To get a replacement you have to go to the Dodge dealer and spent $100 and you this much extra stuff. When the Y-pipe and the hoses are all you really need.The dealer would probably charge you the full 1.8 hours
