Will Rislone Radiator Stop Leak plug my heater core?
No, Rislone® Radiator Stop Leak will not clog a clean heater core. If using it to stop heater core leaks, make sure you turn your heater control to HOT. Some vehicles have a valve that controls coolant flow through the core and is only opened in the HOT position.

Can I install Rislone in my overflow reservoir?
Yes, if direct access to the radiator cap is not available, install in overflow tank.

I accidently added the Rislone Radiator Stop Leak into my engine oil, what should I do?
It is only designed to be added to the cooling system. If the product is installed in the engine oil and the engine has not been started, in many cases you can remove the valve cover and drain the oil leaving the drain plug off. Then use an engine flush washing out the head keeping special attention to the oil return holes that run down to the oil pan. Clean these out and pour the engine flush down these holes flushing everything into the oil pan and out the drain hole. If the engine has been run, you need to take the vehicle to have a professional mechanic evaluate what can be done to clean the inside of the engine. This might include taking the engine apart to clean all of the parts.
