Your cooling system is often one of the most neglected part of your vehicle. With normal age and use, rust, scale deposits, and sludge may form in your cooling system causing increased wear on your water pump and decreased heat transfer. It is important to keep your cooling system clean to keep your engine running at its optimum temperature.
Bar’s Nural contains a mixture of aggressive buffing agents that works to clean and scrub away corrosion build-up and sludge within your vehicle’s cooling system. This allows coolant to flow freely and maintaining optimum heat transfer to help ensure your vehicle’s engine remains at its optimal operating temperature. Bar's Leaks Nural does not contain any acids and will not damage rubber, plastic, or light metals.
Before using any radiator stop leak product, it is important to make sure your cooling system is clean.
With the radiator cool, remove the pressure cap and insert the index finger into the filler neck – rub the underside of the radiator tank. If your finger comes out dirty, the system needs cleaning with Bar's Nural, a safe non-acid cleaner designed to remove rust, scale and muck from the entire cooling system.
We recommend to drain the radiator by removing the lower hose and flush the engine block while warm. This fast flush will empty the entire cooling system in a matter of seconds leaving it clean and scum free. Draining through the small valve may, at first, seem more convenient, however, its slow drain leaves the inside surface of the cooling system similar to the sides of your kitchen sink just after doing a pile of greasy dishes.
A cooling system requiring a cleaner is proof that the system has been neglected. Cleaners will often loosen rust, scale and lime deposits to reveal long existing weak areas of seepage and coolant leaks. It is therefore recommended that every cleaning be immediately followed with the addition of a good sealer/inhibitor – BAR’S LEAKS.
