An old trick is to insert the toe of a ladies stocking into the upper radiator hose (although if she lets you remove her stockings she might not be such a lady...)
Drain the radiator, remove the hose at the head, poke about 6" of stocking up the inside of the hose with the handle of a screwdriver, fold the open end around the hose, refit the hose and trap the flappy bit of the open end under the lower hose clamp. Don't be tempted to stick the stocking in at the upper end of the top hose, it then goes into the header tank and snags on the fins and you have to tear it apart to get it out the tank... guess how I know this. You want it to be sitting neatly inside the upper rad hose as it's easy to pull out with all the muck trapped inside.
It acts as a microfine filter and traps all of the muck floating around the system, especially if you've been rooting around inside there or added a dollop of descale stuff - keep an eye on the radiator, if there's a lot of muck, you can block the system quite quickly. I usually do test runs with a gallon of water in the car. It's worked just fine for all our old cars from the 7's to '30 Triumph Super 7, Model A Ford, all the Alfa's & even the Nissan Silvia Coupe. We have a tropical climate so effective cooling in sunny summer temps is vital
