And if its running hot there's probably air trapped in the cooling system. There's a bleeder valve near the thermostat that can be used to release the air. If that doesn't work you may need a shop with the proper vacuum equipment to drain and refill it for you. As long as there's air trapped inside it won't cool properly. Very common problem on these cars.
