Lubegard 95020 Kool-It Radiator Flush, 16 oz.

Description

Kool-It Radiator Flush is formulated with additives that circulate through the cooling system to remove scale, loosen rust, mineral deposits and combustion by-products from the coolant system and radiator of a car or truck. Radiators use coolants primarily containing anti-freeze & water. Water contains minerals that form deposits over time on the metal surfaces of your cooling system and radiator. These deposits will reduce the heat transfer rate (which can cause overheating), the deposits also can cause corrosion of the coolant system components and reduce the efficiency and life of the anti-freeze. The longer you drive your vehicle without flushing the radiator and replacing the coolant, the more likely that cooling system problems will arise. Extreme driving conditions, such as; operation in hot climates, extended service intervals, stop and go driving, operation in mountainous areas, speeds above 65 mph, towing, etc., increases the chances of harmful deposit formation in the cooling system. DIRECTIONS FOR USE: When used with a flush machine – Follow the manufacturers' instructions. Without a flush machine – CAUTION: Never remove radiator cap if engine is still hot. With engine cool, open radiator drain petcock valve and drain the fluid from the system into a proper container. Close radiator drain petcock valve. Add KOOL-IT Radiator Flush to cooling system and fill with water. Replace radiator cap. Start engine, turn heat on high, and run for 10 minutes. Stop the engine and allow to cool. Remove radiator cap. Open radiator drain petcock valve. Drain water as before. Refill with water and replace radiator cap. Run the engine for 5 minutes, allow engine to cool.
