2010 Build Sheet Info for engine/tranny coolers

[MudDog2007]

My Build sheet 2010 SLT 5.7 3.21 gear says:

Heavy duty Transmission cooler. I dont see how running the cooler thru the condenser can be considered Heavy Duty !

Heavy Duty Engine Cooler. How is a 2 row radiator supposed to be heavy duty ????

I have added a 8 pass Tranny cooler, a new 3 row HD Aluminum Radiator and a add on oil cooler plus trying out a 160 Tstat to handle the heat im seeing pulling my 5K trailer. Numbers were in the low 200s and climbing with the stock setup.

Tranny: What trans does your truck have? You mean ...running the fluid through the 'radiator'? Or does yours have a separate cooler in front of the condenser?

Radiator: Is it the orginal radiator? Anyway, the normal radiators for 5.7's (looking through RockAuto radiators), the specs say they are a 1-core unit. The HD Tk radiator specs say 2-core. It's probably that these have more passes, maybe larger passages (??), and possibly more fins. And of course they're aluminum. Anyway, that's speculation on my part, but the HD radiator says 2-row. The 3.6 also uses a 1-row. At the end of the day it comes down to thermal heat transfer. It's possible a particular 3 row could have less transfer efficiency than a quality well-designed 2 row depending on construction details/materials (size of tubes, overall length of tubes, # of fins etc.). But anyway, you should be good with your new radiator.

Was your truck overheating before?
