My mechanic to me I have a crack in my radiator toward the top will the k-seal help instead of me having to buy new radiator. Thank you

Without seeing your radiator it is hard to say for certain that it will fix the leak. If the crack is in an area where there is coolant it will seal it up. If the crack is in an area that is air with no coolant, the sealant may not get to the area to seal. We have good luck with the K-Seal sealing radiator leaks with our local customers.
