coolant turning brown
 

i need help. i drained the coolant in my 94 fleetwood and refilled it up. After running it for a couple min. the coolant turns brown. I dont think its oil because it just dosent feel oilly. But maybe its a blown head gasket. Ive tried flushing it a couple times with water. will my car overheat with it like that? what should i do?

after flushing it several times im pretty sure its rust soming out. Where could all this rust be coming from? possibly my water pump? is there any way to get rid of all this rust without tearing my engine down? also is it bad for my engine to be running water through it a bunch to flush it out? i try not to let the engine get to hot.
