Try pulling codes
To pull codes, put the key to on position without starting and of the three buttons on the right of speedo cluster hold down the right and left button for a few minutes until the speedo screen changes. Alternately you can get the codes pulled from autozone etc. for free.

If you are getting IPM b0429, it could be a control module. Google "b0429 cadillac forums" for more information.

Not sure if I get the question. Yes alternators can be replaced from another car, however you want to make sure that replacement alternator has same or equivalent part number. I have had not very good luck with buying from salvage ebay seller (part dead on arrival, seller refunded the money though). I ended up getting a a no brand from autozone for about $150, and it has held up just fine for over a year.

If you are looking to change the alternator because of it getting oiled, trying soaking the alternator with brakeclean (chlorine free) cleaner and driving a good distance, this might solve your problem.

air intake, near air filter box

That would relatively normal usage. Coolant is 50% water so repeated heating to near boiling is going to have an effect. Unless you are adding by the gallon, I wouldn't worry.

This is usually caused by a cracked head, which allows the oil to seep into the coolant and vise versa.

Possible leak in vacuum hose. Cracked or broken. May even have fallen off a port somewhere.Try to connect a vacuum gauge to the auto and try switching to different vents and watch for low reading. this should help to isolate it to a local area. Sometimes a fast idle will also tell of same problem

Simply press down on cap and turn counterclockwise. It'll come off like a regular radiator cap. 1.5 seconds

Sounds like the outside air sensor has failed. You may need the dealer to get it fixed.

Turn the ignition to run (one position before starting engine). Display the Oil Life message by pressing the INFO button.
Press and hold the RESET button until the display shows 100% Engine Oil Life.
Turn the ignition off and then start the engine to verify the indicator has been reset.
