ACDelco DEX-COOL Extended Life Coolant 1 Gallon — Pre-Mixed Orange OAT Corrosion Protection

ACDelco 10-101 DEX-COOL Extended Life Coolant is a factory-formulated, orange long-life coolant designed to protect modern engines and cooling systems for extended service intervals.

This 1-gallon container of ACDelco DEX-COOL delivers a pre-mixed, OEM-grade coolant engineered for vehicles that specify DEX-COOL or similar organic acid technology (OAT) formulas. It provides corrosion protection for aluminum and mixed-metal cooling systems and includes a bittering agent for improved safety around people and pets. Use it as a direct replacement where DEX-COOL compatibility is recommended, or as part of a drain-and-fill maintenance service.

How does this coolant protect my engine over time?

ACDelco DEX-COOL uses organic acid technology to form a thin protective layer on metal surfaces, helping reduce corrosion and scale buildup. The extended-life chemistry is formulated to maintain protection over longer intervals than traditional inorganic coolants, which can lower maintenance frequency when used according to manufacturer guidance.

• Extended-life OAT formulation resists corrosion on aluminum and mixed metals
• Stabilized inhibitors for longer service intervals compared with conventional coolants
• Pre-mixed 50/50 concentration suitable for direct fill in most systems

Is this product compatible with my vehicle and cooling system?

Use ACDelco 10-101 where the manufacturer specifies DEX-COOL or an OAT-type coolant; it is an OEM-quality product intended to meet those requirements. Avoid mixing with conventional green IAT (inorganic) coolants; if switching types, follow a thorough flush to prevent compatibility issues.

• OEM-grade formulation designed for vehicles calling for DEX-COOL
• Do not mix with traditional silicate-based coolants without flushing system first
• Pre-mixed for correct freeze/boil protection when used at specified concentrations

What safety and handling features does it include?

The coolant is dyed orange for easy identification and includes a bittering agent to discourage accidental ingestion by children or animals. Standard precautions—store out of reach, avoid skin and eye contact, and dispose of used coolant responsibly—still apply when handling this product.

• Bright orange color simplifies identification and leak spotting
• Bittering agent reduces accidental ingestion risk
• Follow local regulations for recycling or disposal of spent coolant
