Descaling Engine Flush

Star brite Descaling Engine Flush is designed to safely and quickly remove scale, calcium deposits, corrosion, salt and carbon buildup in your engine’s cooling and wet exhaust systems. These deposits can make your engine run hot by restricting water flow through the cooling jackets. Calcium buildup also may damage your engine’s water pump. Descaling Engine Flush will not damage seals, gaskets or rubber impellers.

Before use, remove the water filter and, if possible, the thermostat. Close the water inlet valve (strainer) and start the engine so that the existing cooling water can be flushed out through the wet exhaust. Turn off the engine and pour the product into the strainer. Mixing ratio: 1 liter of descaler to 2 liters of clean water. Start the engine so the greenish fluid is drawn into the system. Once it exits the vessel via the wet exhaust, turn off the engine and let it sit for 15-30 minutes. Then, start the engine again to flush out any loosened contaminants. Try to catch as much loosened residue as possible. The wet exhaust may become dirty due to limescale, for example. Open the water inlet valve and let the engine idle for some time to thoroughly flush the system. Always replace the water filter after treatment. To prevent engine wear, it is recommended to descale the cooling system annually.
