Hi there, I wanna know the exact alternator amperage of my 2011 JGC Laredo. I guess it must be 180 amp. But I'm not shure. Hope you can help me.

Hello,

Your car is equipped with a 160 Amp Alternator (standard from factory)

For the 3.6L Pentastar in the 2011 Laredo trim: 160A is the base and most common alternator.

The 180A and 220A were only installed on: 5.7L HEMI models, Overland/Limited with heavy electrical load. Tow package with upgraded electrical system

The 3.6L Laredo did not ship with 180A unless special-ordered or modified later.

I hope this clear things up for you :) please use 2CarPros anytime we are here to help.
