If you do not have direct access to your radiator and the overflow tank is pressurized, you can install in the tank. Otherwise remove top hose where it connects to the top of the radiator and install product in hose. Reattach hose and tighten clamp.
Yes, it is a permanent solution for your cooling system leaks. What do we mean by permanent? It is not designed to be temporary, or a quick fix like other brands, especially those which do not use reinforcing fibers in the formula. Just like replacing a head gasket will not last forever, neither will Head Seal. But in some cases, our formula can even last longer than if the head gasket was replaced.
No, top off radiator and leave Rislone Head Seal in the system for continued protection and drive vehicle normally.
One (1 liter) bottle treats cooling systems from 9.5 liters to 19 liters. Use ½ bottle for smaller cooling systems from 5.5 liters to 9.49 liters. For larger systems use 1 bottle for every 19 liters of cooling capacity. In very small systems, use 55 milliliters per liter of capacity.
The Xtreme Cool™ additive in Head Seal reduces the surface tension of coolant increasing the wetting ability. This improves heat transfer reducing coolant temperature helping to prevent overheating and leaks.
No, Rislone Head Seal will not clog your heater core, it is safe and effective.
Note: If using Rislone Head Seal 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 when on HOT it allows full flow.
Rislone Head Seal is only designed to be added to the cooling system. If the product is installed in the gas tank, the tank should be removed and cleaned out by a professional mechanic.
Rislone Head Seal 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.
