Job was much more time consuming than expected (acknowledged amateur here). What worked for me: 90 % of work is under the car. To get the drivebelt off, loosen the roller pulley which is just beneath the power steering pump pulley. Then back out the tension adjusting bolt which runs diagonally along the back of the plate that holds the tensioning roller pulley. Then remove the top two bolts of the power steering pump. Loosen the bottom power steering pump bolt enough so the unit can pivot and give you more slack on the belt.
Remove the entire six fastener holding plate from the front of the alternator. (The uppermost nut and bolt, which also directly holds the alt. housing, is best accessed with the battery removed). Disconnect the alt. from the bottom bracket that holds it and shove it to the outward side of car. Disconnect the holder bracket ( 3 bolts and 2 studs with nuts attached). Drop the bracket out the bottom of car. Alternator will then potentially tumble out and do serious damage to anyone beneath it.
Getting the 10 yr. frozen pulley off the old unit was extremely frustrating. I finally deconstructed the old unit using unlimited force and held the armature core rod in a vise while using a 20ö breaker bar to free the nut.
Installation is, as they say, the reverse. Ignore any advice to connect alternator to the bracket and install, it wonÆt go through the space between engine and frame. Push the new alt. up and to the outside of the body. If it falls back down, you are damaged, so brace it somehow or use a helper. Connect the alt. bracket then the alt unit. Reconnect the wiring.
