It's definitely wrong. The tank is too wide. In another thread, somebody else found the correct radiator with the narrower tank. Not sure if all Desert Coolers are wrong or I just got screwed. At the time I just assumed that's the way it was supposed to be and made it work. I won't mess with it until I have to replace it again, hopefully several years down the road. My point in this is to let people know to avoid the Desert Coolers or at least make sure they provide the right radiator.
