Mine has been unhooked since I bought it, the cooler is in front of the radiator and ac evaporater more towards the drivers side. Mine has lines going into the bottom of the radiator to be heated when cold and cooled when hot but not sure if that is stock or if it is a diff radiator. Also the return fitting is leaking, inspected the hose and didnt find anything so I just slapped on a new clamp for now. I found a recall, 1 of 3 for 02 santa fe, on alldata for replacing rotted out cooler lines. I just want a pic or 2 of what it all use to look like, the cooler looks undamaged but it was either leaking or the last ownwer just bypased the cooler after the lines where shot.
