Just bought a 98 Chrysler Sebring with Mitsubishi v6. Currenly has green(assuming IAT) coolant. Owners manual is vague, decided to change to Zerex Asian Blue.
It needs timing belt and water pump done soon. Trying to decide best way to get all old green coolant out & refil with 50/50 premixed HOAT while its in the shop.
Do I need a chemical flush, or will enough distilled water sufficiently clear old coolant out?
I was thinking, drain, change water pump, refil with distilled water. Run coolant exchange machine with distlled water until clear, then run 50/50 until consistent blue color; then check freeze protection level.
Will this work? Or is there a better way to ensure all old is out & no cross contamination weakens the new coolant? If I do need chemical flush, where should it be done in the process for the least added labor/wasted new coolant. I was also concerned if chemical flush sat in block for a few days while pump was changed if that would cause any harm? Also didn't want to errode new pump seals with chemical flush..
Thanks, J
