Bars Nural Radiator and Cooling System Cleaner 150 g.

The cooling system is often one of the most neglected parts of the vehicle. Over time and with normal use, rust, scale deposits and sludge can form in the cooling system, increasing wear and tear on the water pump and reducing heat transfer. It is important to keep the cooling system clean to keep the engine running at its optimum temperature. Bar's Nural contains a blend of aggressive polishing agents that clean and remove corrosion and sludge from your vehicle's cooling system. This allows coolant to flow freely and maintain optimum heat transfer to help ensure that your vehicle's engine remains at its optimum operating temperature. Bar's Leaks Nural contains no acids and will not harm rubber, plastic or light metals. Before using any radiator leak stop product, it is important to ensure that your cooling system is clean. Benefits | Removes rust and scale from the cooling system. Will not damage rubber, plastic or light metals. Contains no acids. With the radiator cool, remove the pressure cap and insert your index finger into the filler neck, rub the bottom of the radiator reservoir. If your finger comes out dirty, it is necessary to clean the system with Bar's Nural, a safe, non-acidic cleaner designed to remove rust, scale and dirt from the entire cooling system. We recommend draining the radiator by removing the lower hose and flushing the engine block when hot. This quick flush will empty the entire cooling system in a matter of seconds leaving it clean and free of dirt. Draining through the small valve may, at first, seem more convenient, however, its slow drainage leaves the inside surface of the cooling system similar to the sides of your kitchen sink just after washing a pile of greasy dishes. We recommend flushing your cooling system every 2 years or 50,000 km or before every coolant change.
