Disconnect the battery
Remove the supentine belt from the altenator pully, you can use a 3/8" drive breaker bar on the belt tensioner, just insert into the square slot on the tensioner and rotate it clockwise.
Remove the power wire and the harness
Remove the mounting bolts 1 under and 2 on the sides.
Just reverse the process to install the new altenator.
Make sure the supentine belt is in the proper position.
Make sure the battery is charged before starting, a drained battery can damage the FETs on the new altenator.
I would rate this a 5 in difficulty. If you have a metric socket set, basic hand tools and a supertine belt tool it's fairly easy repair. You can rent a surpentine belt tool at Autozone.
Disconnect the battery
remove the cowling
remove the supertine belt from the altenator pully
disconnect the red wire on the back of the altenator
disconnect the harness plug from the altenator
remove the bolts holding the altenator to the mounting brackets.
Reverse the process with the new altenator and it it's done.
Make sure your battery is charged before you start the engine a low battery can cause damage to your new altenator.
The belt tensioner has either a square slot in the housing
There you would place a 3/8" ratcher or breaker bar in that opening to releive the tension by pulling it back from the belt. Onse that is done and held away from the belt you can remove the belt. The rest is easy for you need to upplug the electrical connector and unscrew the nut off the altenator next. remove the mounting bolts and it will come right off
reverse this proceedure to install
Hey It is vary simple, first you must loosen the belt. There should be a diagram in you manual or something that originally came with the car if not look it up on google. there is a certain pulley that will loosen the belt when cranked upon. do this and it will make things much easier than i think there are 3 bolts holding it in. And I'm pretty sure when i did it i could get all of them from underneath the car. after you take these three bolts out there are some apparent wres that need a little disconnecting and WALLA its out. than when you put a new one back on dont forget to re tighten the belt with the same pully.
Unplug the alternator remove ground to motor.
Remove serpentine belt.
remove 2 bolts which hold alternator.
replace reverse of removal.
4 out of 10 difficulty.
Only special tool you will need is a wrench long enough to pull back the tensioner.
See the radiator support for location of tensioner and serpentine routing.
While its off, i would suggest replacing the belt too.
