First would be to determine where the coolant is coming from before making any decisions on how you would want to invest your money. Should take it to a locale garage and have the cooling system pressure checked, and a cylinder compression test done to determine if it is in the head gaskets or not, then decide if it should be fixed, or a rebuilt engine put in.
