Did you bleed the system of any air? Are you sure the radiator isn't plugged? Are any of the hoses collapsing?

Some of these vehicles have a bleeder on the thermostat housing. Others don't. In that case, I always bleed from the return line (heater core). As far as the radiator, you may just have an overflow bottle with a pressurized lid on it. If so, that is the only place to add coolant and there isn't a cap on the radiator.
