How can I tell if my 2004 Suburban has a 145 amp or 105 amp alternator?

 

is there a part number on there you could look up? I think most came with the bigger one. but not sure.

 

check your RPO codes in the glove box for one of these...

KW1 13780 P GEN M GENERATOR 160 AMP
KW2 13781 P GEN M GENERATOR 124 AMP
KW3 13782 P GEN M GENERATOR 135 AMP
KW7 13786 P GEN M GENERATOR 170 AMP
KW9 13788 P GEN M GENERATOR 190 AMP
KXB 13790 P GEN M GENERATOR 100 AMP

 

here are a couple of more

7L1 : GENERATOR , A/C 120 AMP
8A3 : GENERATOR, 124 AMP, CS144
8W5 : GENERATOR, 105 AMP
8Z3 : GENERATOR, 100 AMP, HEAVY DUTY

 

This gives me somewhere to start. Thanks.

 

I found the information I was looking for. sap_man posted this link http://www.compnine.com/vid.php? that shows the RPO build information when you enter your vin. Thanks

 

Oh great just shoot down the 10's of seconds I spent pouring over my information to post for you....

lol JK glad you found it...

 

So what was it? I know my 04 burb has a 145amp alt in it. Thats the one listed in my rpo codes anyway.

 

I have a 2000 chevy suburban and need to replace the alternator> I went to buy the alternator but I need to know how many amps I buy 105, 130 Ect.....

 

Take your VIN number to the parts store and they should be able to tell you which one you have OR check the RPO codes in your glove box and compare to the above list
