PETRONAS Tutela Coolant LL Premix is a premium-grade, ready-to-use long-life radiator coolant and antifreeze formulation engineered to deliver exceptional thermal management, corrosion resistance, and component longevity for modern vehicle cooling systems. Formulated with a Mono-Ethylene Glycol base and advanced Organic Acid Technology (OAT) inhibitor salts—free from nitrites, borates, phosphates, silicates, and amines—it protects against engine overheating, freezing, and scale build-up.

Key Features & Performance Benefits

• Extended Service Life: Utilizes Organic Acid Technology (OAT) to resist chemical degradation, prevent deposit formation, and prolong system component life.

• Superior Thermal Protection: Delivers effective heat transfer to protect engines against severe overheating, with freezing protection down to $-37^\circ\text{C}$ / $-38^\circ\text{C}$ and boiling protection up to $125^\circ\text{C}$ (under a 1 bar radiator cap).

• Advanced Corrosion Defense: Offers active corrosion and cavitation resistance across all cooling system metals, including aluminum, cast iron, copper, and brass alloys.

• Seal & Material Compatibility: Fully compatible with rubber hoses, gaskets, and plastic components to preserve system integrity and prevent coolant leaks.

• Ready-To-Use Convenience: Pre-mixed formula eliminates the need for dilution with clean/distilled water, ensuring proper inhibitor concentrations right out of the container.
