the saftest thing is take it to a radiator shop to have it boiled out.
my old oliver 60-70-80-90 manual list a cleaning formula. maybe left out in newer manuals. muriatic acid -2 1/2 pints
formaldehyde -- 1/2 pint
water -----20 pints
drain,remove thermostat and reassemble slowly pour in. warns of danger, will boil when it hits lime. need goggles
let run 2 hours
drain and flush
fill with neutrallzing solution of 1/2 pound baking soda and 10 quarts of water
run for a few minutes.
drain and flush
I have done this in a ford truck that would not stay cool.
solved the problem and causes 4 radiator leaks that had to be soldered.
worked ok in a case 930
amount has to be adjusted for water capacity
only use in cast blocks and copper radiators.
use at your oun risk.

I even do that on a running tractor, drain the system fill with vinagar run it an hour or so. Let cool drain then fluch with a hose. And if I can I flush it from the block drain so evert thing flows back wards

I have on occasion,laid the radiator flat and poured it full of muratic acid.Let is set for about a half hour and flush it out real good .
Flush from top to bottom.The acid will cut both lime deposits and rust loose. What do you have to lose at this point? Yes it may leak and yes it may take a new core ,but what if it doesn't.So it takes 10-15 bucks for the acid.Could be a real cheap fix.

Just make sure that the radiator is made of brass. The acid will totally dissolve aluminum.

Just flush it the best you can with a hose.As long as you get flow and it isn't plugged up.If you get it too clean the odds are greater it will leak. But if you are fixing it up to keep I'd put in a new core and make it good for another 60 yrs.

No matter whuch way you go here - I"d budget for a new thermostat and gasket. You will need it after all the junk finally gets washed out. I"d change the thermostat and coolant after it"s had some time to flush itself out...

No need to buget for those on a JD H they use thermo-siphon-- no water pump,no thermostat just open and close a curtain or shutter to keep hot.
