Coolant Flush, Rust or Stop leak?
Ok well, i started flushing my system with distilled water and have a few questions.
First, after flushing 4 times with 4 gallons each time, there are still rust particles in the bottom of the bucket after draining the radiator. Is this normal(grains of rust)? I removed the top radiator hose and the inside was coated with red/brown rust on the inside so I bought some VC-9 and have drove/idle 1.5 hrs so far. Also put in some simple green and going to let it sit overnight.
Second, after flushing the 4th time i went ahead and installed my coolant filter.
Last, Now if I keep flushing will all the rust come out or will it never come off the inside? I can't figure out how the block rusted since there was antifreeze in there and the glycol shouldnt let it rust. thanks
