I just replaced my upper radiator hose, and have called about every auto parts store in town but cannot find the lower one. Are they the same nobody even seems to be showing one listed in their books. Im also starting to lose some antifreeze. It looks like it runs under the radiator to the other side of the car before it drips down. After driving for awhile or on the highway and stopping it starts smoking from under the hood so I assume it must be blowing back on the exhaust.Anybody?
