Radiator issues (coolant system overhaul)

So i've got the front bumper, rad support, expansion tank, upper rad hose, basically everything disconnected, the only thing keeping me from getting to the front of the engine is the radiator and i think it's just stuck on the wedge clips, it moves around and there's play to it but if i could figured out how to undo the wedge clips on the sub frame, i could just slide it straight out...

any tips or a walk through even of what needs to be done to undo those darn clips. My babies sittin in the garage waiting for her new parts to go in.

Are the AT lines disconnected from the cooler in the radiator? Or, have you removed the cooler? The radiator is held in place by (on my car) a Torx screw and a plastic pin. Those are out if your radiator as you can move it. Sometimes the rubber supports at the bottom of the radiator can get wedged in the wrong position. I'd use a flashlight and check the supports and the plastic (of course) that rests on the supports.

Just did this two days ago, I had to disconnect the transition lines and power steering lines, no screws held mine in place, but I still found it pretty wedged in, so I got under the car and pulled the radiator towards the engine and that got it free and then I just pulled it out from the top.

Sucks I have to do this all over again on Sunday for the water pump.....

so managed to figure out how to disconnect those wedge plates, reach inside the sub frame rail and youll see where a tab locks in to the frame rail just depress that tab and it slides right off, detach the radiator from i think its the ac/oil cooler i dunno im tired, but ill take pictures when i put it back together just waiting on new water pump pulley from ECS to get here with a fresh belt, anyway once the radiator is out it makes it a million times easier to get that lower rad hose off, and access the water pump and thermostat. really should have taken detailed pics while i was doing to tear down to write a diy on this, i know there's a lot out there but none of them really seem to address doing it with the nose of the car taken apart (which in my opinion is easier atleast on our automatics since you might as well do the mechanical fan delete at the same time)
