hey wirenut: I always buy the "kit" with the hoses and clamps included.
Never had much success with trying to re use the hoses back, even if they are brand new. The barb fittings are tough to get hoses off, then re install but it can be done.
You can do a warrant claim on cooler and hose kit.
Fyi, if the get the story from tech. you need to put "dye" in the oil system, to prove its the cooler, good luck !
Thanks Mike...I did take a picture of the cooler with the oil dripping.
