I have been towing my rv (24 ft bumper pull) the last few weekends and my CTS says around 215 deg F (coolant) and 185 (trans). I bought this truck last fall and have not towed during the hot 100 deg weather. Do you guys think the temps are ok? The temps go higher sometimes on the hills, then the fan locks up and cools it down. I put new thermostats in when I did my headgaskets last fall. The truck runs freakin awesome and pulls like a freight train no complaints there. I am just wanting to know if that is where the 6.0 likes to run.
Coolant and Trans Temps while towing questions???
