Starter and Alternator question - The 1947 - Present Chevrolet & GMC Truck Message Board Network

MAK191 · 05-23-2012, 11:55 AM

So, my 2002 5.3 (from a Yukon) came with everything except a starter and alternator. I do not have the VIN, my computer came from a different truck so I can't decode. As I search online for a replacement I have found a couple options (there may be more).

Alternators
105 amp
130 amp
145 amp
Question : Which one to get, will the 105 amp be adequate with E-fans? Ive heard they need extra power. Is this true?

Starters
9 tooth
11 tooth
And 1-2 kw
Question: I have no idea how to figure out what I need.

Thanks for any help
-Mike
