When did Honda switch to blue coolant?

Honda, the renowned Japanese automaker, made the switch to blue coolant in the early 2000s. This change was part of the company's ongoing efforts to improve the performance and longevity of its vehicles.


The Reasons Behind the Coolant Color Change


Prior to the switch, Honda vehicles typically used a green-colored coolant, which was the industry standard at the time. However, as technology advanced and new coolant formulations were developed, Honda decided to transition to a blue-colored coolant for several key reasons:



  • Improved Corrosion Protection: The new blue coolant formula provided enhanced corrosion protection for the engine and cooling system components, helping to extend the lifespan of these critical parts.

  • Better Thermal Efficiency: The blue coolant formula demonstrated improved thermal properties, allowing for more efficient heat transfer and better overall cooling system performance.

  • Easier Identification: The distinct blue color made it easier for mechanics and owners to quickly identify the type of coolant being used in the vehicle, reducing the risk of mixing incompatible fluids.


By switching to the blue coolant, Honda aimed to provide its customers with a more reliable and long-lasting cooling system, ultimately enhancing the overall ownership experience and vehicle durability.


The Transition Timeline


The transition to blue coolant was a gradual process for Honda, with the company implementing the change across its model lineup over several years. The first Honda vehicles to feature the blue coolant were the 2001 model year Accord and Civic, followed by the rest of the Honda and Acura lineups in subsequent years.


Today, the use of blue coolant is standard across the majority of Honda and Acura vehicles, reflecting the company's commitment to providing its customers with the latest advancements in cooling system technology.
