Type 2 Blue Engine Coolant - 1 US Gallon

The Honda OL999-9012 is a genuine Type 2 blue engine coolant specifically formulated for Honda and Acura vehicles. This ready-to-use, pre-mixed 50/50 solution comes in a convenient 1 US gallon jug, designed to provide optimal performance and protection for your vehicle's cooling system. This coolant offers robust temperature protection, preventing freezing down to -34°F and preventing boil-over up to 265°F. Its ethylene glycol base is enhanced with Honda-specific corrosion inhibitors that safeguard critical engine components, including aluminum heads, blocks, radiators, water pumps, and heater cores, from galvanic and electrochemical corrosion. The distinct blue color is a key identifier, ensuring the correct fluid is used and preventing contamination with other coolant types. To maintain peak performance and longevity, it is crucial to adhere to Honda's recommended service interval of 5 years or 60,000 miles for flushing and refilling the cooling system. Mixing this Type 2 blue coolant with other colors like green (Type 1), pink (Toyota/Subaru), orange (Dex-Cool), or yellow (universal) is strongly discouraged, as it can cause detrimental chemical reactions, leading to sludge buildup, clogged radiators, and potential damage to the water pump. For a complete system flush and refill, it is recommended to use 2-3 gallons, as most Honda/Acura cooling systems have a capacity of 6-8 quarts. This genuine Honda part, with manufacturer part number OL999-9012, replaces older part numbers such as CU08730, OL999-9001, and OL999-9002, and is backed by Honda's factory warranty, ensuring reliability and peace of mind for Honda and Acura owners.
