Rinsing the cooling system is pretty straightforward. All you really
need is a garden hose. Although there are many cooling system chemicals
available, and I have used them regularly over the years, the one time I
opened the engine within a week of using a cleaner as directed I found
that it was plugged with rusty paste. There are lots of cleaners, though,
so they must do the job for others.
What has worked best for me is to disconnect the heater hoses, hose out
the sediment in the heater core, then reconnect them.
Next, I disconnect radiator hoses and flush out sediment in that.
Then I remove the thermostat and force water through the block.
Rinse heater core and rad again before reassembly.
When you refill, pour in the prescribed quantity of antifreeze, then
top off with the water. Doing this compensates for the left-over rinse
water that does not always drain completely and would dilute your mixture
if you pre-mixed AF and water.
