Cool LLC II is a high-performance long-life coolant developed to draw out the performance of horizontally opposed engines to the utmost.

Where conventional products use ethylene glycol as their main ingredient, Cool LLC II uses propylene glycol for its excellent heat exchange efficiency. This provides exceptionally high heat dissipation and heat absorption.

It suppresses engine stresses such as overheating and power loss at their source to maintain stable performance. Its specially formulated additives also strongly suppress cavitation caused by disturbances in coolant flow.

By preventing the minute impacts that erode metal surfaces, it protects the condition of the cooling system over a long period.

Working together with the main ingredient, the additives stabilize coolant temperature and maintain an ideal thermal environment for the engine.

Cool LLC II provides antifreeze protection even in extreme cold of -40°C. This greatly exceeds the previous -20°C resistance, allowing it to perform in any region or season.

A powerful non-amine corrosion inhibitor suppresses rust and keeps the cooling system clean.

For users who keep driving actively, and horizontally opposed engines facing harsh environments, Cool LLC II is a long-life coolant for drivers throughout all four seasons: gentle on the engine without compromising performance.

Recommended replacement interval: 1–2 years.
