Rusty Cooling System
Hello,
Just dis-assembled my 6.5 down to a complete block (pistons, crank, and cam still in it). I cann look into the water jacket around the cylinder jugs and it is very orange (rusty) in there. On some of the walls and coolant passages there are some retty large amounts of rust forming. I was wondering if anyone knows a trick to cleaning the system out well? I was just going to flush it multiple times with coolant, but i dont think it will be strong enough. Is there a chemical you can buy?? Im thinking that i am goin to assemble the heads back on the engine, oil pan, timing cover and so on, plug the water pump holes, then fill the block and heads with a garden hose and some type of cleaner, and just keep runnin flushes through it... SOund like a good idea?

The engine came from philadelphia, not in a real warm climate but not arctic either....

Here is my plan for the flush.. I am going to put my old heads back on with the set of victor reinz gaskets that i bought in a set off the bay, torque the old tty bolts a little to make a decent seal(im going to be getting arp headstuds for the final assembly), then flush it sitting on the enigne stand. I was actually thinking clr to begin with, so i will get some of that and radiator flush also. I will just plug the block right up (coolant wise) and let it sit overnight, then run the hose through it and drain, and repeat. Dumb me, i should have flushed it good with the old headgaskets and heads on there, but i wasnt thinkin then.... I really dont care about ruining the victor headgaskets, i am going to get felpros now(been on a felpro spree lately)... So we will see how that works... Im going to order a new set of heads next week hopefully, really need to work on the underside of the block now (oil pump, pickup, pan, and rear main). I am also going to check for cracks, i hope there arent any after the bad new on the heads...
