Go to public library to get the schematics used by the professional mechanics...it is on line with pictures. Have note card to keep track of what you are doing. Remove the top protector cover to the radiator so you can see what you need to. Make notes on or find the map of the serpentine belt so you can put it back on. Find the automatic adjuster spool to the serpentine belt tensioner. You have to turn it with a socket wrench to release this tensioner. Then you have to remove the serpentine belt. Remove the bolts to the alternator and replace it. The alternator you buy should have some directions or you just have have the ability to see how it fits in. once it is secure, then put back the serpentine belt back on by putting the belt on last at the tensioner. Toyota MAKES A Lexus SO YOU HAVE TO EITHER BE FAIRLY MECHANICAL OR PAY THE PRICE OF OWNING ONE so you have to enjoy overcoming this and enjoy knowing you can do it with a little time, patience, prayer, and perhaps a friend.
