A mixture of white vinegar and water will loosen calcium & oxide deposits.
If it's an old system, drain the coolant from the block and radiator, refill with the vinegar and water solution (I use 50/50 here too, and the vinegar is cheap enough). Drive it around the block a few times, and then let it cool down enough to drain it again. If it looks particulary bad, you can do it a second time.
If you can still see stopped up tubes through the radiator filler neck, the radiator should be pulled for a professional "rodding out" procedure.
Backflush with water by undoing the hoses and introducing the water in the reverse direction of normal flow.
Take note of the condition of radiator and heater hoses, replace any that are suspect.
Close everything back up, and refill with 50/50 antifreeze and distilled water. Barring any leaks, you should be good for at least three (3) years.
Considering where you live, a thorough job of checking out the cooling system can avoid a lot of trouble later on.

thank you guys, i plane on doing the flush with that aid of these instrustions and my haynes manual.
I am somewhat embarrassed to admit how long I go between antifreeze changes on all my vehicles, including the Healey. Probably closer to 5-6 years. My 1981 GMC truck, maybe, has only been changed a couple of times. Only issue I ever had was the Dex (orange color) antifeeze that some manufacturers used around 2000 that turned to mush after a couple of years. Anyway, my opinion is that sometimes we change fluids more often than necessary. Probably just opened a can of worms here.
