Got two of these 16" efans and 34" rad, Do u think the fans will pull to much watts for the stock(105 amp alt)? Also have two pin blackbear harness on the way.

amps=watts divided by volts
18.333=220 divided by 12 -each

Any one know the amps the 05+ or ls1 pull?

 

Not sure, but my '06 came from the factory with a 160-amp alternator (KW1).

 

Anybody?

 

You'll be fine. Those fans "seem" like they are lighter duty... The 05-06 fans are some heavy duty units and I run them with the stock 105 amp alternator. No issues. The 2-pin harness was a most excellent move.

From your first post, did you buy that 34" radiator? A 2500 should come stock with it.

 

Came with 34". Done some more research myself and will go with the 05! I just installed Pace setter LT and needing a tune. Wanted to go ahead have it set up for the efans.

 

if you measure 34" from barell to barell that is the smaller radiator ...you need to measure from inside fin to inside fin

 

Yea i know. 2500 stock have 34" besides i measured it before i bought them. I am going to use them for little while. Then i'll get 05+ efans. Then use these on the RCSB i plan on building!
