On the 14th-gen F-150 this is a hose-off job rather than a drain-plug job. Most trucks in this generation have no usable radiator drain cock, so you pull the lower radiator hose at the driver-side corner after taking off the lower air deflector with an 8 mm socket. The hoses use constant-tension spring clamps, so real hose clamp pliers are the difference between a 20-minute job and a knuckle-busting hour. Expect roughly 3.5-4 gallons out of the radiator and a couple of quarts of old coolant still hiding in the block, which is why a distilled-water flush is worth doing if the coolant is dark.
What varies is capacity and how many loops you are dealing with, not tool sizes. Every engine here takes Motorcraft Orange prediluted (WSS-M97B44-D2) — already mixed, so no water gets added. The thing people get wrong is the refill: filling the degas bottle to the mark and calling it done leaves air in the heater core and, on EcoBoost trucks, in the turbo coolant lines. Either vacuum-fill it or idle it with the heater on full hot and a spill-free funnel until the fan cycles and the vents blow hot, then re-check the level over the next few cold starts.

Tool sizes are the same across 2.7 EcoBoost, 3.5 EcoBoost, 5.0 V8 and 3.5 PowerBoost — 8 mm (some 10 mm) deflector screws and spring clamps on the lower hose. Capacity differs: plan on roughly 3.5-4 gal (13-15 L) total for the engine loop on the V6s and 5.0, slightly more on PowerBoost; verify the exact figure for your VIN. PowerBoost also has a second, independent low-temperature coolant loop with its own reservoir for the power electronics that is serviced separately and is not touched by an engine drain.

Motorcraft Orange Prediluted Antifreeze/Coolant, part number VC-3DIL-B, meeting Ford spec WSS-M97B44-D2. It is already 50-50, so nothing gets added, and it should not be mixed with green, Dex-Cool, or Ford's older yellow coolant.
Many do not, and the ones that do are hard to reach behind the lower air deflector. The standard approach is to remove the lower air deflector with an 8 mm socket and pull the lower radiator hose off the driver-side corner of the radiator.
A drain-and-fill through the lower hose typically takes about 3.5-4 gallons (13-15 L) on the 2.7, 3.5 and 5.0; buy two gallons of prediluted for a simple refill and four to five if you are flushing. Confirm the exact capacity for your engine in the manual.
Best method is a venturi vacuum fill tool on the degas bottle: pull 20-25 in-Hg, hold it to check for leaks, then draw the coolant in. Otherwise fit a spill-free funnel, idle with the heater on full hot until the cooling fan cycles and the vents blow hot, then set the level cold at the MAX mark and re-check after a few drive cycles.
