the 04 4wd should have the larger radiators.

 

How do I identify. Is there an RPO code? Measurement? How do we confirm.

Is there any programming needed. I have HPTuners.

 

I think it's 34 " for the radiator and yes you have to turn them on in your ecm

 

This would be a gift for my brothers 2004 RCSB 5.3 LM7 Stepside Z71.
I read earlier you have instructions and or videos available. I am an experienced wrench puller. Just looking at all the Ducks.
Still undecided and in GA, my bro is in the Tampa Bay area 33578, I'll need him to measure.
PM me an offer to consider?

 

Found the settings.

 

For reference, these are the settings in my 03 Denali taken from an 06 SSS stock tune. (P59 PCM)
