Your coolant drain plug is in the drivers side bottom of radiator by lower hose..You can use
Ford Premium Gold Ford WSS-M97B51-A1 purchased from Ford Dealer about 20.00 per gal. OR you can use Zerex GO-5 Coolant From Napa about 11.50 per gal..DON'T USE ANYTHING BUT ELSE IN THE 6.0 I use the Zerex GO-5 from Napa. Also use distilled water. If your doing a complete flush check the link from BPofMD above !!!

Reason: Edit
Save yourself a ton of time...place 5 gal bucket directly under lower rad hose connection and pull the hose ...alot will come out quick from both sides. If hot, be careful...but this will speed up your flush cycles...approz 4-5 cycles with distilled water.
there are 3 coolant drain plugs on the truck. There is one on the radiator. one on the left side of the block and one on the right. the one on the right is hidden above the starter. the only reason to remove the ones in the block would be to completly drain the block as well.
When I did my coolant flush I just open the drain plug on the radiator, when that stopped I pulled the lower hose (If you pull the lower hose first be prepared for a coolant rush.LOL) and than pulled the plug on the left side of the block. I didn't mess with the right side with the starter...

Wow, 5 flush cycles! This spring I was planning on replacing all hoses, T-stat and flushing with only 1 distilled water cycle after garden hose flush. Was planning on using a flush kit fitting through the heater hose with a garden hose with T-stat out...drain rad and pull both block plugs...fill with distilled and run for 5 minutes then drain the distilled and final coolant fill. Not planning on changing to an ELC, staying w/conventional coolant in my 2000 7.3 w/SCAs (Pencool 3000). You think additional distilled cycles beyond an intial flush and one distilled fill/drain is achieving added benefit? I am willing to do it if needed, just seems like I might need to get some help out of Wal-mart with the 40 gallons of H2O. Interested in feedback on this.

Since the 6.0 takes 27.5 qts and I think the 7.3 takes about 30 qts..50/50 is somewhere close to 3.5 gallons coolant and 3.5 gallons distilled water. Your method should work, I just did it the hard way...wasn't to sure about using tap water...where I live its pretty mineralized. Since the flush cycles only dump 3.5-4 gallons each time...4-5 flushes will only require 16-20 gallons of distailled water. Shouldn't be more than a buck a gallon. Diesel Technician Society

Cheezit, do you recommend pulling both block plugs for the typical drain, flush and fill maintenance? I understand each side block drain will drain an additional quart or two. However, I see some doing it and many never doing it for their flushing routine. What's your take on it?
