try undoing the radiator hose's from the radiator and get a garden hose and a rag use the rag as a seal and stick the hose in the bottom of the radiator and turn the water on full blast with the upper hose off the radiator ,you will need to hold it in. see if you get the water to come out the upper inlet of the radiator with the same force as the water going in. if not you have a cloged radiator .
