05 getting hot towing

[SINCAL_DMAX]

Runing up a grade with my 5th wheel 37ft weekend warroir. Truck got up to 250 collant temp fan was running. Any ideas truck was running 3-4 gear running 3200 rpm. Truck has stock intake with flat filters. Didnt gm have a service bulletn for the air filter to convert to a round style filters. Or what can i do to drop the collant temp.



Thanks for the input

that has alot to do with it. specially if its 90+ degrees out. What mods are done to the truck? lifted truck? trailer loaded?

Truck is a ccsb 6 inch lift 35 inch tires. trailer is loaded with 5 quads and water in trailer. would getting rid of the muffler and or cat help it.

Definitely running straight piped, or moving up to a 4" exhaust will help reduce EGTs. That would be the first step, then Id look into towing specific tuning if its something you do often.

I dont know what the egts were but the collant temp was what was hot. if i do a tune for towing how will i get it to pass smog in CA.

Hmmm....LLY overheat....where have we all heard that before?

LBZ mouthpiece and intake (or CAI), larger exhaust come to mind to help. What else was out there?

Cai ???

cold air intake is what CAI stands for

What he said. ^^^ Did wonders for my heat issues. Ditch the cat/muffler and swap out the mouthpiece. That will help your mileage as well.
