Yea, I have seen that thing- I bought one two days ago! I put in the new rad and bottom hose (42.50 from Ford) And the lettering on that end was messed up, all I can read is 45 degrees- as in "rotate hose 45 degrees" Now it makes sense!! I simply pushed mine on and it held so I didn't bend the tab, but it IS lined up with the groove on the rad. My Ford garage had NO IDEA!!! Now I see that I simply have to bend the tab a bit to keep the hose from rotating 45 degrees, and YOU will have to bend the tab to loosen it from the slot on the rad and rotate the hose to release it. I would remove that tranny line first.The line and lower neck are way too close. I also removed the overflow/fill tank. Thank you so much for the pic!! I hope you make out as well as I did! Also, this is a dual application rad, so if your careful you CAN cut close to the end and re-install with a clamp. The instructions say to leave the o rings ON the neck to help seal the hose, even with a clamp.
