It wasn't a question of the tools. I bought the two tools called out for the M119 engine 103 589 01 09 00 (stubby 8mm) and 603 589 00 40 00 (fan pulley counter holding tool). They both worked great. The issue is there is not enough room for the 8mm stubby and a 3/8 ratchet between the radiator and the fan clutch.

As for sawing off the protruding plastic that is what I thought of. However those holes have two purposes. One hole is to hold the clampp for the trans coolant line (it attaches to both pieces of plastic) and the elongated opening is to hold the bottom of the fan shroud.
