If you really want to do it right, NOT just fast or cheap, and don’t like to have the AF left in the system there is only one way…
Blow the water out of the limes…
Pump the antifreeze through the lines (not forgetting the water pump)…
Then blow out the antifreeze…
Your P traps will already be done and any residuals left will be only the trace amounts of AF left behind that will take little rinsing to remove…
A little more time and a minor expense, and no worries…
Every fall I read the dozens of post recommending to just blow out the lines, then every spring I read the dozens of post about cracked fittings and leaking water lines…
So there are choices but the right way never seems to be the quickest way nor the cheapest way…
