Our 2000 Taurus is due for a coolant flush. I've read up on some DIY
approaches to doing this but wanted to see if anyone could share any
practical experience doing this.
I know better than to run the engine empty of coolant with the garden
hose turned on and inserted into the resevior. I don't want to sieze
the pistons or crack the aluminum with the entry of cold city water
into the loop.
Is it enough to empty the coolant from the rad and block, refill with
tap water, run and drain again? That leaves me with probably four
gallons of waste that I have to dispose of. What about draining once
and just refilling?
