You were overcharged. Parts are excessive, you could have bought Ford parts [ford list shown]cheaper than that. It matters if you have a single cam or DOHC but anyway..orings come with our housings.. Labor excessive by at least a half hour [he charged you 2.5 hrs] Then what is his warranty? Ford's is 12 K or 12 months on repairs. Didn't put new antifreeze in?
