Anybody know where the engine block drain is for the passenger side on a 97 5.4L 2wd? I found the one on the left side 5/16 allen plug just aft of the oil filter. I can drain about 3 1/2 to 4 gallons of antifreeze out with the one block plug out and the radiator petcock open. The cooling system holds 20.8 quarts so I'm not getting everything out.

Why not just fill it back up with fresh water, run it for about 15 min. and repeat the drain process? Or you can use a prestone flush kit with great results.

I was getting a good amount of rust, scale and sediment draining from the left side drain so I thought it would be a good idea to see what comes out of the right side.
