Folks, I've just (finally) gotten the water pump off my 2n (had to find a 13/32" box wrench to remove the fan!).

I'm replacing it because it was overheating, but the bottom hose was cold (suggesting no flow through the pump). I flushed the radiator and water flowed freely out the bottom, so I figured it must be a worn pump.

But before I put the new water pump on, I wondered if I should flush the coolant channels in the block. Is it likely for that circuit to get plugged? If I should do it, how? Just a hose in the top? Should I put the new pump on first, or wait?

Yeah, too many questions, but I want to get this right - I need my old friend back in service ASAP!
