How do you change an alternator on a 1990 Lexus LS400?

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. TIMOTHY FOR JOHN
