89 240sx alternator replacement.

[nani]

hello i wanted to know if you guys recomend to take it to a shop or if i could replace the altenator home. Ive read in some posts that this is a little bit hard, and there were many parts that have to be removed in order to reach the alternator. i will gratly appriciate your help thanks.

do you have a basic socket set? how about a 10,12,14mm wrench? if you have that you should be ok. do it yourself, its over $100 in labor.

I have the same car as you and i just removed the alternator yesterday and just about any one can pull this one off. There are two bolts on the braket and a long lower bolt. Then the two tensioner bolts. All you have to do is losen the two braket bolts and the lower one. This allows it to move around and then you use the adjuster bolts to take the tension of the belt off the pully. Remove the three losened bolts and dont forget to remove the positve cabe and the connetor clip on the back of the alternator. To put the new one in you just reverse it all up. I believe youll need a 12mm and 14mm and ratchet the do this. Let me know how it goes.

If you are gonna be replacing it, just do the 110 amp upgrade - costs less than a 240sx alternator believe it or not (autozone pricing).
