ACDelco DEX-COOL Extended Life Coolant 1 Gallon — Orange OAT, OEM-Compatible Corrosion Protection

ACDelco 10-101 DEX-COOL is a factory-compatible, extended-life orange coolant formulated to protect modern engines from corrosion and elevated-temperature wear for long service intervals.

This 1-gallon jug contains ACDelco's DEX-COOL extended life coolant (orange) designed to meet OEM specifications for many domestic and import vehicles that call for OAT (Organic Acid Technology) formulas. It helps maintain consistent heat transfer, offers freeze and boil protection when mixed to recommended ratios, and includes a bittering agent to discourage accidental ingestion. Packaged for convenient pouring, this coolant is ready to mix or top off according to your vehicle manufacturer's guidelines.

How does this coolant fit my vehicle's maintenance schedule?

ACDelco 10-101 DEX-COOL is formulated to match extended service intervals specified by many manufacturers that require DEX-COOL or equivalent OAT coolants. Use it when your owner's manual lists DEX-COOL, or when performing a full system flush and refill to maintain recommended protection periods.

• Meets OEM DEX-COOL compatibility for applicable models
• Ideal for full system refills or top-offs after coolant service
• Supports extended drain intervals versus conventional IAT coolants

What protection does this coolant provide against corrosion and overheating?

This organic-acid based formula delivers corrosion inhibition for aluminum and other engine alloys, while maintaining thermal stability under normal operating temperatures. It helps sustain effective heat transfer and inhibits scale and deposit formation when used at proper concentrations.

• Corrosion inhibitors for modern engine metals
• Thermal stability for reliable heat transfer
• Helps reduce deposit buildup in cooling passages

How should I use and mix this 1-gallon coolant safely?

Follow your vehicle manufacturer's dilution recommendations—typically a 50/50 mix with deionized or distilled water for year-round protection. Use appropriate PPE when handling, avoid mixing with incompatible formulations, and follow local disposal rules for old coolant.

• Mix 1:1 with distilled/deionized water unless manual states otherwise
• Do not combine with IAT (green) coolants without a full system flush
• Includes a bittering agent; handle and store away from children and pets

Who is this for? Vehicle owners and technicians replacing or topping off coolant systems on cars and light trucks that specify DEX-COOL or equivalent OAT antifreeze. It's especially suited for those who follow OEM extended service intervals and want a readily available, factory-compatible coolant in a convenient 1-gallon size. Always confirm compatibility with your vehicle's owner's manual before use.
