Factory radiator cap for the 2008 4.7L engine is 18 lb.
Years ago we used to replace the standard 15 lb cap with a 7 lb cap.
This was done to put less stress on an aging cooling system.
I have done this many times and the cooling system never seemed to suffer at all.
So, what is the opinion of using a 7 lb cap on a 2008 JGC Limited w/ a 4.7L??????
I may just try it and keep an eye on the temp gage as well as my OBD / Torque temp readout so I get actual temp numbers.
If so, I will report back in a while.
