BTW about the egg shells: If you have a small leak in your radiator, you can use black pepper to patch the holes. Use about 2-3 slightly heaping teaspoons and put it in the radiator cap (not the reservoir). It works because black pepper will not burn at those temps in radiator fluid. When the pressure and heat squirt out small amounts of fluid, a grain or few get stuck and patch the hole temporarily. 2 spoons will solve your problems for a few months.
