Absolutely! If you're seeing a lot of crusty rust in the block with the hoses off or with the water pump off you need to give it a real, good flushing and probably wouldn't hurt while your cleaning out the block to get the radiator into a shop and have them flush and test it. I would say that would be particularly important in the part of the country that you live in.
