The lower line coming off the side of the radiator is looking a bit deteriorated and the connection is seeping a bit. Can someone tell me the hose size? The dealer wants $31 for the part. This hose has very little bend in it and I would think that a pc of straight hose would be fine. Thanks.

i used a straight piece, thinking 5/16, same as power steering hose,

Mine was 3/8" ID ATF Hose bought from local auto supply store. Canadian Tire or other parts supplier should have it.

yes 3/8 ,
