Coolant Pump - 103 Engine - "how tough is it?"

[tivoliman]

I have the shop manual, and the listed tasks...

It seems straight forward, but is it?

Seems like the manual suggest taking several steps, remove some bolts, and replace - is that all there is? I'm considering if I should do the job, or hire it out?

Per the Mercedes shop manual...
Coolant at engine and radiator ..............drain, pour in (20-010).
Air scoop ...................................remove, install (step 4).
Viscous fan clutch ..........................remove, install (20-312).

Belt pulleys of fan clutch and coolant pump .remove, install.
