    follw top hose to engine block ,thermostat should be under the connecting bit to engine , also when motor overheats does the thermo fan start ?a lot of the times where a engine overheats its the electric switch that turns the fan on thats the problem , but from  what you have said it does sound like thermostat is stuck closed 

    The only way to test a thermostat is to remove it & drop it in hot water.If it opens it's OK.But if you are going to the trouble of taking it out you migt as well replace it with a new one.
