Sinopec Great Wall Zhuowei YF-2A Organic OAT Long Life Engine Coolant All-Season

Sinopec Great Wall Zhuowei YF-2A Organic OAT Long Life Engine Coolant

Great Wall Zhuowei YF-2A is an organic acid technology (OAT) engine coolant built on a carboxylate formulation, supplied as a red transparent, odorless liquid. It forms a dense, stable chemical adsorption film on the metal surfaces of the engine cooling system, providing long-term corrosion protection. This engine coolant is silicate-free, phosphate-free, nitrite-free and amine-free, resists hard water, and is designed for a long life of up to 6 years or 300,000 km.

Product Overview

This organic OAT coolant is a universal engine coolant for both light duty and heavy duty vehicles. Its nearly loss-free carboxylate chemistry is widely accepted worldwide, and it improves heat transfer thanks to excellent hard water compatibility. The coolant stays stable during long storage and keeps outstanding thermal conductivity and protection even at high temperature, helping to extend the life of engine components. Because it contains no environmentally harmful or toxic chemicals, it avoids substances that could act as potential carcinogens and helps protect water and soil ecosystems. It suits automotive cooling systems in every climate, resisting boiling in summer and freezing in winter.

Key Advantages

• Nearly loss-free carboxylate chemistry, a globally accepted formulation technology.
• Harmless to rubber hoses and seals, extending seal service life.
• Long-cycle corrosion inhibition that fully suppresses cavitation.
• No supplemental coolant additive (SCA) top-up needed in heavy duty engines, keeping maintenance simple.
• Excellent hard water compatibility and improved heat transfer.
• Meets both light duty and heavy duty vehicle requirements as a universal engine coolant.
• Long life of up to 6 years or 300,000 km between changes.
• Biodegradable and of low toxicity to people and organisms, environmentally friendly.

Applications

• Cooling systems of commercial and industrial heavy-duty engines and vehicles.
• Domestic heavy-duty diesel engines as well as imported American heavy-duty diesel engines.
• Light duty and heavy duty vehicles that use an engine coolant.
• All-season operation across a wide range of climates.

Why an Organic OAT Coolant Matters

Conventional coolants deplete their corrosion inhibitors over time and can leave deposits that reduce heat transfer. An organic OAT coolant such as this long life engine coolant works differently: its carboxylate inhibitors form a thin protective film only where it is needed, so the additive package is used slowly and lasts far longer. This organic OAT coolant reduces maintenance, avoids the need for supplemental coolant additives in heavy duty engines, and keeps the cooling system stable for years. For operators who want a durable engine coolant that protects all metals, resists hard water and stays environmentally friendly, this long life formulation is a practical, all-season choice.
