Why am I doing this? I've written this many times here.
I may be among a minority but I've never had any problem bleeding the cooling system using the procedure described in the RAVE (absent removing the block drain plugs). It is not wrong, regardless of what others write here. And I've done it several times with great success, including three or four times last month when I again flushed and refilled the system.
In my experience, I don't need to cross my fingers, wear a tinfoil hat, or park my truck facing uphill. (What would members in Florida do? There are few hills.)
Tip #1 - Fill and bleed the system with the truck stone cold.
Tip#2 - Follow the RAVE procedure and refer to Tip #1.
Tip #3 - Setting the heater to high does nothing. Coolant flows through the heater circuit at all times when the engine is running. There is no valve or control in the heater circuit.
I start by disconnecting the lower hose at the radiator and the top hose from the thermostat and position it to be below the water pump inlet to allow the system to drain. Once it's drained fully I reconnect the hoses and fill the system with distilled water from the expansion tank, with the tank raised 8" per the RAVE instructions until fluid flows from the bleeder screw hole.
I then replace the expansion tank in its mount, fill the tank to the seam and drive it a few miles. After letting the system cool fully the level in the tank is typically down ~3/4". I typically drain and refill with distilled water three times, after which I drain and then refill with Prestone concentrate. After topping up after driving following the Prestone concentrate fill i can finishing adding the rest of the second gallon of Prestone which by my math gets the truck to a 50/50 coolant mix.
As I said, no standing on one leg and touching my index finger to my nose, no crossing my fingers, no tinfoil hats and no parking on a hill. It's worked for me every time for nearly ten years. It may not work for all but it's worked perfectly well for me. Good luck.

I'm with mln. I never had a single problem when I had the factory system.
Nose of the truck up slightly, take out the bleed valve, raise the expansion tank. Fill from the expansion tank till it starts coming out the bleed valve. Cap the bleed valve, finish filling the expansion tank. Set the expansion tank back in place and cap it off. Open the bleed valve again and pour some water in if it needs any. Let it run a minute, rev it a little, then fill from the bleed valve again. Top off the expansion tank if you need to. Do it again after your first drive cycle.

Since reading this post, I ordered 2’ of 5/8” clear high temp hose from HPS to change out the old hoses ... HPS 5/8" ID 16mm High Temp Reinforced Braid Clear Silicone Hose - Sold per Feet
