Start the engine cold with the radiator cap off. You should see coolant flow as soon as the thermostat opens. Check the front of the radiator for debris that may be clogging the cooling fins. If you see coolant flow and the fins are clean, then you may have to get the radiator flushed out. Also is there is any leaking at the weep hole on the water pump, replace it. Is the cooling fan coming on? There may be a possible air pocket trapped in the system also.
