Anybody with a specific product recommendation? ~~_/) ~~ www.maps.org Re: Radiator stop leak for heater box leak?

Remember, once added to your cooling system, it does circulate throughout the entire system. There is a high probability you have a hose connection problem that is allowing coolant to leak. Heater cores are not a high failure item.
