Prestone makes a flush chemical that I have used before that seemed to work.

I've had good luck with their two part flush chemical setup, used in conjunction with their flush kit. You have to cut the heater hose, splice in a garden hose connection, and follow directions. You'll be absolutely amazed what comes out of your cooling system.

Be sure and put the correct amount of DCA4 in there for cavatation prevention.

Don't use the acid flushes, especially if you just put a fresh rad in. Use the soap based flushes, they will say for the main ingredient, Surfectant ( fancy talk for soap ) That with one of the flush T kits will do the trick. Good idea to install a set of drain petcocks on each side of teh block, where there are block drain plugs for thorough draining
