Start by replacing the thermostat if it continous check for a clogged radiator, defective water pump and cooling fans-

Feel the radiator front for cold spots. Are the cooling fans working?

One way to test for a bad water pump is to squeeze the upper radiator hose when the engine is hot and idling. Careful, because the hose will be HOT! If you do not feel much coolant circulating through the hose when you rev the engine, the pump may be bad. The other cause might be a bad thermostat that is not opening properly (remove and inspect the thermostat), or a clogged radiator.
