What is the best way to go about flushing my radiator without taking my truck somewhere? Is there a drain plug?
yes lower drivers side on the back side of the radiator, its a white plastic bolt looking thing. then there is also a plug in the engine block, takes a big allen wrench its on the bottom near the oil pan on the drivers side about 3/4 the way back. drain it then if you really want it cleaned out fill with water and repeat the steps after running the engine for about a minute, dont run the engine without water or with the drains open

You can also do a search here; it's been discussed before. If you follow the proceedure defined in a Haynes manual (or the Ford repair shop manuals), it would not be nessesary to fill and drain the radiator to flush. Drain once, leave the plug removed, and continue to fill in the "overflow" tank until the draining fluid is clear.
Give an answer, they learn for the day; suggest a search, they learn for a lifetime.
I remember years ago, my dad had an old chevy celebrity that blew a head gasket or something so a bunch of oil leaked into the coolant. After he got it fixed, he got a Prestone kit that had a T-connector that you cut and install inline on one of the coolant hoses, and a spout thing that replaced the radiator cap. The T-connector was threaded for a garden hose, so he turned on the water, started the car & flushed the whole system til the car was up temp.
Obviously that kit wouldn't work on our trucks, as we no longer have radiator caps, but you could probably do something similar with a hose in the coolant bottle as Bucko suggests. You can run an engine with the drain open, as long as you're filling it at the same time. I would probly use just the radiator drain.
