I have searched for this but have not found the answer. About a month ago I replaced the heater core in my 2001 xj. I had a hard time finding one that had the correct bends in the inlet/output tubes. The third one I found was close but the box had been opened. Anyway i installed it and I continued to smell antifreeze.(and it will fog the windows after it get warm) So now I am thinking someone had bent it to fit there jeep and decided to take it back.(fearing it would leak) I guess I will have to do this again! So were do I find one that will fit correctly. All the part stores around here have the same brand and does not fit with in the plastic housing correctly.

 

I had the same problem. You just have to bend them carefully and make sure you do not crack any of the welds.
