It might sound strange but before there was anything like Bars leaks or those little pellets like GM sells, my dad used to use "sodium silicate" (egg preservative).

If he had a small hole in his radiator that produced even a small steady stream of water, he would pour in about 1/2 gallon, just set there with the car running and you could watch the leak stop. He would leave it in for about 1 hour of run time, flush it out and refill with water.

Ok, I am talking about the 50'S and 60's here so don't laugh too hard. I would almost bet that some of the old timers around here have heard of it also.

There are more effective products on the market now. Just bringing up some old remedies that I learned from my dad.
