If your hoses are hot, then it sounds like a potential cooling fan issue.
-let it get hot and plug in a bus reader to check that cooling temp sensor is reading a believable temperature. Sometimes they go bad and report a temperature that's too low, so the fan never activates. If you're boiling out coolant and the bus temp reads below 100C then the sensor's probably bad.
-check to see if the fan ever turns on. Turning on the AC should make the fan turn on much more frequently.
-check to see if your car is the 2 speed fan version or 1 speed. 2 speed versions have a resistor mounted on the fan body by the fan motor, and those resistors go bad.

It could be other stuff, but those are easy/common failures to check first
