Pulled into the driveway last night and popped the hood cause I thought I smelled prestone and the whole top of the engine was covered with prestone. Couldn't for the life of me see where it was leaking from so I started at the most obvious place to check for loose clamps which was a plastic tee that the dealer splced into the heater hose to flush the enging coolant. As soon as I touched the hose clamp with a nutdriver it broke completely in half. It was in there about a year is all. Went to the hardware store and got a threaded brass nipple and reconnected the heater hose. Only lost about a half gallon of coolant. Anyway I don't know if it was a faulty piece or just a POS to start with but if you've had one of these plastic things installed on you rig, may want to get rid of it.
