• Made in Japan with OEM quality standards

This thermostat regulates engine temperature by controlling coolant flow through the radiator. As coolant temperature rises, the bypass valve gradually closes the bypass hole, directing more coolant through the radiator for enhanced cooling. The 78°C opening temperature provides slightly lower operating temperatures compared to standard 82°C thermostats, making it ideal for high-performance or warm climate applications. Compatible with various Honda Accord, Prelude, Odyssey, and Acura MDX, Legend models equipped with specific engine configurations.
