milkshake

[shady]

I have a Flex with the 3.5 that has the dreaded water pump failure. The pump is internal & driven off the timing chain & when it fails the coolant goes right down into the pan which results in a milkshake. Good news is that it was discovered early enough that there seems to be no other damage. Engine runs fine & quiet. So, other than real frequent oil changes, is there something else I can do to flush out the milkshake? Rislone, Motor Flush? My thinking is that running the engine with new oil, the remaining coolant will evaporate thru the PVC & burn off.

I'd....not plan on the idea that antifreeze will evaporate anytime soon. I'd buy a case of the cheapest oil you can get, even recycled oil, and plan on running it through a few times of rapid oil changes, checking the catch pan each time.

Cheap oil changes, couple of cans of Berrymans or maybe a pint of Kerosene - maybe 3~4 changes with runs to full op temp during each.  No, antifreeze won't evap and it will eat bearing surfaces, so don't wait.
