3.1 Alternator on 3.4 DOHC?


supersniperkilla

Recommended Posts

My alternator is on the fritz and i can tell it is on its way out...i can get a great deal on a remanufactured alternator for $20 :high5: but it is for a 3.1

 

Will this work?

Yes it will.

 

I put the alternator from my 88 regal in my cutlass without any real issues. Just had rotate the casing so that the mounting points lined up.

 

No shit??? I could have sworn the mounting points were different. Did they all line up, or just a few?

The alternators themselves were identical. I had to unbolt the 2 halves, and rotate the front piece so that the mounting points lined up correctly. I forget which way I had to rotate it,but if you compare a 2.8/3.1 alternator to one from an LQ1, you will see what I mean. The alternator is technically the same, just the angles at which the 2 halves of the case are joined is different. And Yes, all the mounting points were the same.

 

I remember fighting like a bitch trying to get the 2.8 alt to fit on my 3.4 to no avail, then when i got fed up and put it next to the one i had pulled out i saw that it was basically a mirror image of the 2.8 alt. So thats when i rotated the front half of the case and it slipped in like a glove.

Correct. He would need a 3100 alternator, in which he would have to verify that he could rotate the housings.

 

crazy K in now on a mission......

 

update:

sub-mission 1: appearance match confirmed...

PART NUMERS DO NOT MATCH... But are close matches. The only difference between the alternators is the rear snap on plastic casing.

 

Anecdotal evidence:

I once got an alternator for a 3100 from a junkyard, pulled off the shelf. It was the correct alternator, except for having a incorrect rear plastic shell. That alt had a cooling duct. It was from an LQ1.

 

 

 

MATCH CONFIRMED.

i am not sure when the 3.1 motors stopped in production :redface:...the alternator is off craigs list and the guy just says 3.1L

 

He does not specify whether 3.1 or 3100

i called the guy and he said its from a 1999 montecarlo 3.1.... i did more searching and found that those are 3100 cars...

 

so in theory if i just turn it around like people are saying, it shall work not?

DO NOT ASSUME. later model 3100s have a different bracket, such as the 02 GP broken in my driveway... but the 99 monte carlo has the same style as a 95 Cs... so that is safe to say...

 

No ear rotation is needed. only the rear plastic cover would need changing, if the basic alternator is correct. If the pulley is a different size, you could change the pulley, or belt to match.

looks like different part numbers from a 95 3100... But the images appear similar:
