I just bought a 2000 Millenium with 160K on the clock. (My 2nd Millenium and 3rd 996) The car has intermix issues as in oil in the coolant but no coolant in the water. The engine/trans are coming out next week but I am not sure how to clean the cooling system after I rebuild. Any suggestions? I suspect the oil cooler but will go all the way down with this much mileage...
