GM had a specific radiator and engine stopleak especially used for this problem. I went to GM and bought a package of 8 tablets, made of a vegetable combination, and added this to my radiator. This seemed to seal the leak significantly. I nursed the vehicle along adding these stopleak tablets every 15 to 20 thousand miles, whenever the leak would reappear.

I'm pondering if I should try this as a pre-emptive strike type of thing.
