If the top hose is hot and the bottom is cold then that would point to two possible problems 1) Your radiator is plugged and not letting coolant through or 2) your water pump is no longer working and not circulating the coolant through the engine as it should.
Removing the t-stat is not a solution, if the top hose is hot then the t-stat is open and letting hot water through, the water flows from engine to radiator via the top hose. If you run the Legend hot you will ruin the engine.
