what should i do to prepare my car for installing a radiator? (koyo to be specific)

i found the write-up for a fluidyne install on fc3s.org, so that's covered, i jus need to know what needs to be done prior to the install

flushing? how? anything else?

 

I did it last summer on my 83. Not much preparatin required. But afterward, make sure you get all the bubbles out of the system: I let it idle with the radiator cap off and added water as necessary. Watch out for the heater hoses bursting or leaking. Make sure you have the right pressure cap.
