How to clean up the water pump/manifold hose fittings... - The 1947 - Present Chevrolet & GMC Truck Message Board Network

Before I put brand spanking new radiator and heater core hoses in my truck I'd like to clean up the water ports on the manifold, and the water pump. They're rusted and corroted as hell, and would basically make these new hoses worthless.

Since the connections are dry now I thought I'd just pull out the dremel and see if I can clean them up. Any better ideas? It looks like the connections for the heater core on the manifold and the water pump can be replaced with some new brass pressure fittings. Should I just yank them and replace vs. trying to clean them up? There's tons of junk on the outside and in the opening...
