Nice writeup, should be helpful to the folks out there in MB-land.

Ironically, I just replaced the tensioner rod on my '93 two days ago. They do break too often, and too easily. It's more tedious than difficult to replace them.

Air pump is still fine on that car, with 107K on the clock. The fan bearing, on the other hand, is starting to concern me. Not looking forward to that repair.

On the coolant pipe running across the front of the engine, isn't there a seal where it attaches to the thermostat housing? Aren't you supposed to replace that seal anytime it's disassembled?
