Its a matter of preference; my preference would be to not remove the cooler front standard unless there is a known discernable reason to, doing so has a PIA level of 8 out of 10. If no issues I leave it in place, remove the rear standard and re o-ring both ends of the cooler, becaise thats what goes bad and leaks, the big black o-rings. I change the rear contact gasket because the rear standard is off anyway.Yes, that’s what I was referring to, I would personally never go in that far and not pull the front of the oil cooler, it will be getting its’ new gasket as well.
Below is a copy of the well written R&R on oil coolers which also addresses Nicks concern of not hanging the cooler off of the front plate.
I have a copy of Gooch’s coolant flush which describes turning on and running the Heater control to Full heat to remove air pockets:

Just the WP out and fan pulled back, I don't see a big increase in front standard R&R access. Radiator, fan and fan shroud out, yes.
Gooch's flush procedure is a good one. It is not however intended as written to be a ything other than a coolant system flush. It is not intended to be a count system cleaning procedure for oil contamination in the coolant system. Easy to modify its basic method to detergent wash out and coolant install, basically many many more detergent flush cycles with tap water, then a 4x flush of tap with distilled water and same very last cycle, drain the RAD and top up with 4 gallons of concentrate to have a 50/50 net mix.
