Fan is bad, fan relay is bad, a coolant leak somewhere externally, a coolant leak internally, most shops where I live can check your coolant system INCLUDING a block test for 25.00, I suggest you look into that before you keep replacing parts guessing at it, and the problem is really an internal problem or blown gasket on the engine good luck.

Check for a collapsed hose. I had one that had a soft spot in the radiator hose. When it heated up, it would squish together, and slow the flow of coolant. Also, check for an air pocket in the cooling system. You may have to "burp" an air bubble out. Finally, check to see if the cooling fan on the radiator comes on. You may have a bad relay.
Good Luck,

sounds like you have a fuel issue. running a bit too lean above idle.
