How do I get it into my radiator that does not have a cap but only a reserve for the overflow

This is a minor, although messy problem. Simply disconnect the upper radiator hose to get access to the radiator fluids. You'll probably need a funnel and maybe a little duct tape. My neighbor used a gallon milk jug as the funnel and his hand to make sure the fluid got where it was supposed to be. Also, if you drain it at any time, just take off the lower radiator hose.

this product can fix a crack in the engine block of a car?

Although it is impossible to guarantee that it will work in every situation, it does quite often seal up block leaks...... It's most always worth a try, before you resort to rebuilding an engine. Thank you eric
