Hey how are you ,I will Try to Help you with This Issue

yes it does matter , you can look at the alternator itself you took off and match brand and part number and should have a label showing 140 or 160 .

you do not want to go to low or to high ,will give electrical problems

if you have like a towing package on it , most time it will be 160 , but give me vin# ***** will try to look it up or help you how to identify it

Please Let Me Know
Thank You

We actually have 3 on this 125,140 and 160

if you click on link to view pdf file you will see RR for alternator , look at the back of it where battery cables hooks up , it should tell you

the vin # by itself will not specific, since it could light duty , no added options , 125 usually, towing package , 140 or towing and nave and dvd etc

then 160

where is old alternator

I sent you all 3 part # , compare to label if no specific number indicating AMPERAGE

Please Let Me Know
Thank You
