IMHO using any sort of flush product is asking for trouble. Open the block drains and flush with a garden hose at the output hose opening in each head by the waterpump. Flush all components with all the hoses off (you should replace them). After a water flush, running the car for a few months with good coolant will clean up a lot of scale. You will probably want to drain and water-flush again in a year or so. If there is a lot of scale you may want to water flush the radiator separately. Back-flushing with plain water is most effective.
