Replaced the radiator in wife's Mercedes GLK this weekend. They made the radiator, electric fan, PS cooler, and condenser where they all snap together and are apparently meant to be pulled as one unit. The radiator is just narrow enough to fit between the frame rails but the PS and refrigerant lines take up just enough space to make radiator removal/installation almost impossible without disconnecting all of those lines.
I don't want to evacuate the AC just to swap a radiator.
I fought it for a few hours and finally persuaded things back into place without disconnecting the PS and AC lines. If they had made the radiator a 1/4" narrower, it would have been a 30 minute job.
