Look it up on the one installed
Alternator
Depending on which engine you have, an alternator could range from $140-195 (USD) at Autozone.com.
I don't know where to tell, but replacement alternators range from 100-140 amps for that model year.On the top & to the right of the alternator you will find some numbers look for 3 numbers followed by an A which stands for Amps such as 105 A. The numbers are usually hard to see, you can take a piece of white chalk & rub over them to get them to show up better.
