coolant flush question
friend has a 03 impala I did a heater core flush with straight water, core was clogged with a ton of crap, water was a deep orange for like 30 minutes of water flow.
I also did the same thing with the radiator and hoses, both pulling the thermostat and flushing the block as well as running through the radiator. water was ran until it came out clear. coolant was replaced with "universal antifreeze".
she was back later that night with her overflow tank absolutely filled with a clay/putty like material (dark orange).
I re-flushed it and have done 2 more flushes since then trying to get all this crap out of her cooling system. she is still having issues and i am trying to get a final solution.
sorry about the book. but any ideas on a good product to use to get all of this crap out of her cooling system?
