I've got a newly rebuilt 235, new water pump, and new radiator. About 15 miles on the engine. When I initially filled the radiator with water, then drained it, it came out rusty. I have filled and drained iht system three times, and it still looks like the coolant is brown/red sludge.
the engine over heats, and spits water out of the over flow hose. I just bought and installed a coolant recovery tank, and now it's full of sludge.
Any suggestions on cleaning this up? I can't believe how dirty this is after all the work.

I am currently digging back in to a 1953 3800 (one ton) with a nine foot bed. I've owned it since 1979, and drove it until 1982 (or so). My wife got me involved in restoring it back in 2002, got the body removed and the frame redone, then things came up. Now I am retired and starting again. If anyone is interested I have photos on Imagur ( https://timwhiteblues.imgur.com/ ). I live way back in the woods in the Ozarks on 40 acres at the end of a 2 1/2 mile private road.
