Thinking about buying a 2001 king ranch with 109000 miles on her. She has the 5.4 L motor. Any issues with that year I should be aware of before purchasing? I have heard of previous head problems on earlier models. Hoping it was fixed by 2001.

 

What are common Ford 5.4 engine problems

 

Major rust problems on radiator core support in areas where roads are salted. I don't know where you live.
