Hi,

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.
