How to Flush out a Mack 237 Radiator & Block?

I ussually just use the Fleetgaurd DCA 4,run it for a few hours and drop it out if it looks dirty,then put another lot in.I`ve never pulled apart a motor that has had that stuff in it that has been dirty,everything looks perfect if it`s had that in it.

thanks for that biggy. was hoping to getaway with just one lot.

I get the DCA 4 in about a 2 litre container,which gives you a couple of goes at it.I don`t think it`s all that expensive,I`ve got to get some more so I suppose I`ll soon find out.

I got the 3 Liter one bout $60

Well i finally filled the radiator with the cleaner, after emptying the dam out of the block and radiator filled it up with clean water and the cleaner, after 3 hours driving around in 40 degree heat, dropped the water, instead of a dam falling out the green swamp fell out, flushed it out about 5 more times and the green started to reduce each time, so a few more flushes and she should be clean to fill it up with green cordial.
