Replacing alternator...
So my alternator went this morning, i wanna replace it myself so before i go ahead i wanna just make sure I have this right:
First turn belt tensioner counter clockwise to loosen belt and remove from alternator pulley
then disconnect alternator cable and loosen the bolts and remove the alternator
put new one one reconnect and then replace belt and tighten tensioner
that all sound right?

(from the 2003 shop manual)

I read you should disconnect the battery terminal before doing any work on a vehicle. Not sure how important this would be in a simple replacement here, but 90% if the things i've seen, remove neg/pos first.

Clockwise, not counter clockwise. The rest sounds accurate. When you get to the bottom two bolts just loosen then a little bit then you can pull the alternator/generator straight up; i.e. the two bolts do not have to be removed.

No need to disconnect both terminals.

The negative terminal should be disconnected first a this renders the positive terminal divorced from any relationship to "ground". This is such second nature to me when fussing with anything electrical--on any vehicle, for the last 55 years--that I do not even think about it as being a required step.
The tensioner is indeed turned clockwise to relieve the tension--another of those things so blatantly obvious I have never bothered to commit the detail to memory...

Calling it an alternator, although can be argued it is the incorrect term, is an acceptable way to describe that rotating thingymabob that generates 12vt. power for your car
Typically, the "genalternator" comes with its own pully and no need to swap your existing one. You may have changed the pully for a different diameter, on your existing one, but is a fairly hardcore thing to do for a couple reasons. FWIW... this device can be spun in either direction with no output change whatever (cheaper ones may not hold up at higher RPM's going in reverse direction). If flipping to the opposite direction, it is best to remove the pully and apply some thread locker and re-install it to proper specs. It could possibly be spun off under high-loads. The internal cooling fan will not be as efficient, but will work fine.
As for replacement, if you are running lots of additional electrical load on your system, you may consider a high-output one. The later model cars tend to have more electrical items in the attempt to save fuel mileage. For example, the '12 Mustang has an electric steering pump. Funny thing is, that ultimately, the fuel is the only power source for the car, so wonder how much fuel it actually saves... dunno

I will never do that with the stock K ever again.
