I have a really bad rust problem going on in my engine, Where all coolant runs (ex. 305 Block, Water Pump, Radiator, Intake manifold etc.) there is a lot of rust. Is there any way I can run something through the system to stop or get rid of the rust? Thanks in advance.

its iron, iron rusts, not much you can do about it. Flush the system really well if you feel there is loose stuff in it, and refill it with good antifreeze.

if there is a buildup or rust crap in teh radiator, maybe get a new one

 

Drain the radiator take out the thermostat, stick a hose in the radiator and flush the hell out of it. Then fill it up and let it run a few min, then drain again, flush add coolant and go. Sounds like just old coolant. Was the engine sitting out somewhere? Never heard of running engine rusting. Check for floating clumps or milky coolant. Other then that sounds like it needs flushing. I took my van to my mechanic, he pulled out all coolant, flushed it then toped off, cost 125. Dont take to somewhere like jiffy lube, they dont flush, just recover and fill.
