Ford has had a problem with the intake manifolds on these vehicles. They actually had a recall on them back in 1999. Unfortunately though the recall ran out seven years after the vehicle was put in service so for your car that would have been around 2004. The manifolds were not built henough to withstand heating and cooling. They started to fail and leak coolant in the front collant runner. I will attach the recall and a technical service bulletin for you to read. The Ford intake manifold is very expensive, but you can get one from NAPA for around $400. Labor time is around 5.5 hours at whatever the shops hourly rate is.
