Havent' taken possession of my 2011 LML Denali yet but was wondering do these trucks have fuel and tranny coolers in them? Just preparing my parts list, I am already planning on a FASS 150 titanium, Ridgerunner tunes, delete emissions.

Probably to save a few million dollars lol. I'm glad the interior is starting to get built a little better.

Injectors barely return fuel and the cp4 dosent. So no need to cool the returned fuel, adding a lift pump won't change a thing. No need for a cooler unless you do a cp3 conversion...

I was never aware of you cp3 converted it you needed a cooler? I I'd however crack open my filters on the lift pump an it was pretty darn hot. Is it maybe a good idea to make this a near future add on?

Big trans cooler and NO fuel cooler. What them do away with the fuel cooler is beyond me.

The trans cooler has 2 extra rows over the LBZ/LMM that are not plumbed and does not do much cooling. The low trans pressure keeps the trans cool in the LML.

As far as the fuel cooler delete on the LML; the extra capacity in the tank ( 36 gal. ) does all the cooling. Still needs a fuel cooler IMHO.

I forgot about the lower line pressure, I know my friends 15 Denali never got over 150 towing my truck to George's.

Agreed. I have seen the plastic melt enough to clog a lift pump on a LML. Granted it wasn't stock.
