[DML] Re: Sediment in Cooling system

["Harold McElraft" <hmcelraft@xxxxxxx>]

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.
