This is a time consuming replacement- the engine has to be tilted forward, the power steering pump comes off, and the alternator bracket has to come off as well.
Here is removal procedure, replacement is just reverse procedure:
Rotating the Engine for Service Access
Engine Tilt Strap
Important: Ensure that the drive belt is aligned into the proper grooves of the accessory drive belt pulleys.
Important: Do not disconnect the power steering pipes from the power steering pump.
Those are factory directions that all techs use in order to replace the alternator. If you dont do the very first part - remove the engine struts and rotate(tilt) engine and secure it with an engine strap, no, you wont be able to remove the alternator. And the directions do tell you to remove the wiper control module
i have removed dozens of these using the directions provided.
If you want I can opt out and see if another expert has directions that differ than those GM put out for it.
