Need to replace alternator 2007 Cobalt LS 2.2.
Local auto part store has a 120 amp and 140 amp.
Which one is stock? Will the factory wiring harness handle the 140 amp?
Thanks in advance

call the dealership with the vin and they'll tell you what size you have. it normally boils down to one car had all the bells and whistles (sunroof, power windows, power locks, ac, etc.)

Here is what the local autopart stores are telling me about what size of alternator the 07 cobalt 2.2L LS should take.
The car has no options at all. AC, Radio, 5-speed.


Pep Boys says 140 amp
Autozone says 120 amp
O'Reilly says 120 amp
Napa say 120 or 140 amp

I will call the dealership w/ the VIN and see what they say.

I'll let you know what i find out.

Yup take that 140a unless there's a huge price difference
