You didn't tell us a thing about your cooling system.

When does it get hot:
Idle?
On the highway?
Both?

What temp is it running?

After market or factory gauge?

What kind of fan do you have?

Do you have a fan shroud?

What temp thermostat do you have?

What's the age and condition of your radiator cap?

Are you running coolant or straight water?

What's the condition of your hoses?

Does your lower hose have a spring in it?
