I always use fresh, distilled water and never use mineralized tap water in my cooling systems. (See the section beginning at 5:54 through 7:21 of this video for details on flushing with distilled water.) I did clean the system during this service but did not find much debris. The flush procedure is described in your factory workshop manual if you need "official" guidelines.

Yes, almost a guarantee...Wise to pick up a replacement radiator drain plug before this task. If the original plastic plug stays intact, you'll have a new one on hand. I have two spares on the shelf.

At 12-minutes into the video, I share the vacuum filler method that has become popular. My only concern is that this method of filling the system does collapse the radiator hose(s). (You'll see the upper hose collapsed in my demonstration.) For a hose in new or newer/good condition, this should not be a hardship or cause trouble. An older hose could be an issue. Once vacuum is established and held with the tool, the siphon hose gets placed in the gallon jug(s) or a tub with clean coolant and water mix. (I bought a plastic cement mixing tub just for this purpose and keep the tub clean.) If you do not want to buy a vacuum filler kit (inexpensive at Harbor Freight, Amazon, eBay, etc.), the traditional method you describe will work. Heat on high, the fan speed is more for keeping the heater core from overheating than anything else...Fill the radiator to the filler neck and the overflow tank/reservoir to above its fill level. After warm-up to normal operating temperature, the engine is shut off and allowed to cool down. Coolant mix siphons into the radiator and replaces air in the cooling system. Level the coolant in the reservoir...After several warm-up/cool down cycles, the siphoned coolant from the reservoir eliminates all air in the cooling system. The reservoir must remain at least at its fill level during this cycling back and forth. Turning the heater on is always wise when using this method. Do not let the engine overheat, as there may be air gaps within the coolant. When normalized, drive the truck; after parking and cool down, watch the coolant level in the reservoir for several trips. Burping the system this way, always keep the coolant level normal in the reservoir.
