How do I do a coolant flush a 351W?

[mnm99]

I have one of these necks in the middle of the hose. http://www.summitracing.com/parts/hre-3423 . I first removed the lower hose, drained , connected , filled and ran the car. I did this 4 times. Brown crap still came out...I then just disconnected the lower hose, stuck my garden hose in the filler. Water came out of the lower hose and radiator the same time. I did this until it was clear.. There was still a lot of crap! I then connected the hose and was able to put 2 gallons of distilled water in. I think I'm going to drive it for a week or so. Drain it again and add the 2 gallons again. If I do this 3 or 4 times I should have all distilled water in the entire system. Then the last time I'll drain , add 1 gallon of anti freeze and the rest distilled.

Just loose the clamp on the lower hose and move it out of the way. Work a screwdriver under the hose till water drains out. You have about four gallons of coolant so have enough pans to catch it all. I have used a short plastic box that I bought at WalMart. The ones with a lid used for storage.

Or the pan you use to drain oil into will work.

I understand, but if I fill the top of the radiator and it drains at the bottom how does it flush the ENTIRE system?

Easiest way to flush the engine is remove both radiator hoses from the radiator,you'll also need to take out the thermostat.......
then stick your garden hose in the top hose a few inches and turn on the water full blast,it will go thru the block and out the lower radiator hose....
