Found a trick that worked awesome. Looped a piece of wire over the small tang of the PHH clamp, pulled down and it rotated the whole clamp down to where I could get a vice grips on it. Took 10 seconds.
Now I just have to get the lower coolant pipe bolt loose so I can rotate the pipe back and out of the way...any tricks for that? I couldn't get good leverage to try and bend the pipe enough to get it out of the way...maybe I should try the wire trick for that too
