I'd like to know the procedure you used to do what your suggested I had to tear my entire front grill take off the condenser radiator and fans off as an assembled unit and as you'd suspect I had to drain all the fluids out to do this. Once i got it back together I started getting this code and I can't still to this day get the valve because it's still on back order.
I have a 2022 3.0 Diesel engine only have 6100 miles on it and it’s leaking oil, pretty sure it’s the rear main seal. Didn’t know these truck were having oil leak problem till TODAY.
