Here’s my issue.
My truck runs great until I’m pulling my 24k lbs 5th wheel up 6% grades at 60mph then the temp shoots to 230* not sure if it will go higher but that’s when I back out of it.
I will mention my egts never go over 1250* here’s my break down my trucks a bit modified.
I stay in the tow tune from DRD.
Also I am not losing coolant.
2015 RAM 3500 dually
BD Rumble B 364.5 second gen swap
Mishimoto radiator and inner cooler
Industrial Injection Performance fire ring head and 50hp injectors
Banks monster intake
ARP 625+ studs
4” exhaust with inline BD exhaust brake
Any thoughts will be appreciated
