I suppose you could pull the water pump to see if it has those sheet metal impellers instead of cast. Some of those break off.

Maybe i should try to do the radiotor test removing the thermostat to see if the water flows or not!

water does not really flow until the thermostat opens at temperature!

Do i still need to pull the water pump to inspect and flush the radiator to determine if its blocked somewhere?
