ive got a lot of rust in my cooling system. im pretty positive its coming from the heater core because the guy who had it before me had the intake and return lines to the heater core jumped. for some reason i didnt flush the heater core when reconnecting the lines .....so im wondering if CLR being run through it will help to alleviate most of the problem before i flush it? also, what is the best method of flushing the entire system?
