Coolant Filter on Gas Motors
I've got a 4.6L in my 2000 Lincoln Town Car. Spent the morning saturday flushing the cooling system. I got 159k miles on this car and I don't think the T-stat or the coolant had ever been changed. ...

Use a chemical flush that will disolve the scale. We used that at the dealership for neglected cooling systems. Not necessary if changed at proper time/mileage intervals, but if it's been neglected, it will help clean it out.
