if you dont have any leaks check for excess pressure in expansion tank,or air bubbles in coolant which would indicate head gskt,feel top hose to make sure thermostat is opening,good luck

you will need to check all you hoses and seals around thearmostat and water pump, look for any white deposits around them, or any splits in hoses, also check your radiator for leaks. you could try some radweld to see if this helps. it could be headgasket, have a look at the oil cap on engine to see if you have any creamy looking deposits, as this is a good indication, if h/gasket has blown.
