Alternator noise failure V6 - replace with high output?

Wow. This thing was making the KLUNK-KLUNK sounds like crazy.

Thought about stopping for a burger on the way home, but decided to not press my luck.

Pulley locked up completely with a horriffic squeal right after I took this video in the driveway.

I think factory alternator is rated at 105 amps. Any reason (other than cost - which isn't a major issue) to not upgrade to a higher-output alternator? Quick look online is showing models for the 2.8 motor that rate 160 and 200 amps.

 

Should also mention that I just installed the OPTIMA yellow-top battery (as part of the battery tray rehab project).

 

besides the added cost and absolutly no need , just put a stocker back in it.
unless u plan on doing a massive car stereo the 105 amp is more then overkill
ive run 5,000w competition stereo systems on a stock 105amp alt with 2 batteries

 

Thanks.

I tried to find a "correct" OEM GM model, but they seem to be officially discontinued at gmpartsdirect.

So, took advantage of the "cyber Monday" discount at Autozone, and ordered a new (not rebuilt) 105-amp replacement, with lifetime warranty. I hope I don't have to use the warranty.

 

be prepared to use that warranty , i gave up on parts store alts, and starters .
now id rather go hunt threw the junkyard to find a working oem one then deal with the parts store crap

or if im lucky enough i can find quality rebuild parts to just rebuild my own starters or alt's

 

Replacement arrived.

Made in Mexico.

Taco'd between two trash bags filled with spray foam. Clever lads.

 

I'm not sure what's wrong with the old one.

 

She lives again!

 

Ran it around the locale today. A bunch of WOT pulls. Not one hiccup. Life is good.
