The Chevy Trax uses Dex-Cool long-life coolant (orange), GM’s organic acid technology (OAT) coolant, typically in a ready-to-use 50/50 mix. Use Dex-Cool or a Dex-Cool-compatible OAT coolant, and avoid green or universal coolants unless the label confirms Dex-Cool compatibility.
Understanding the Trax’s coolant type
Most Chevrolet Trax models rely on Dex-Cool, GM’s orange-colored long-life coolant. Dex-Cool is an OAT (organic acid technology) formulation designed to protect aluminum engines and reduce corrosion over time. When servicing the Trax, use Dex-Cool or a compatible Dex-Cool-approved coolant. Mixing Dex-Cool with green (conventional) coolant is not recommended, and switching from one type to another typically requires a proper flush.
Common options you may encounter when purchasing coolant for your Trax:
- Genuine GM Dex-Cool long-life coolant (orange), the factory-recommended option.
- Other Dex-Cool-compatible long-life OAT coolants from reputable brands (look for "Dex-Cool compatible" or GM Dex-Cool compatibility on the label).
- Pre-diluted 50/50 Dex-Cool mixes or concentrates with distilled water, as directed on the coolant bottle.
Conclusion: The Trax typically requires Dex-Cool or a Dex-Cool-compatible OAT coolant, with most setups using a 50/50 mix. Always verify with your owner's manual or a Chevrolet dealer if you’re unsure about a specific year or regional specification.
Maintenance and replacement guidance
To keep the cooling system in good working order, follow these guidelines and consult your manual for year-specific intervals.
- Check the expansion reservoir when the engine is cold; the level should sit between the MIN and MAX marks.
- Inspect the coolant color and clarity. It should be the orange hue of Dex-Cool and free of sludge or grit; brown or milky appearance warrants a system flush.
- Follow the replacement interval suggested for Dex-Cool by GM—commonly around 5 years or 150,000 miles (or as specified in your manual for your region and model year).
- When replacing or flushing, use a 50/50 mix of Dex-Cool and distilled water unless the label or manual specifies a different ratio; if switching from a different coolant type, perform a thorough system flush first.
Conclusion: Regular checks and timely replacement with the correct Dex-Cool-based coolant protect cooling system components and help prevent overheating and corrosion.
Summary
In short, Chevy Trax models typically take Dex-Cool long-life coolant (orange), usually supplied as a ready-to-use 50/50 mix or as a concentrate to be diluted with distilled water. Use Dex-Cool or a Dex-Cool-compatible OAT coolant, and avoid mixing with green or non-Dex-Cool coolants unless explicitly approved by GM. Always refer to the owner’s manual for your exact year and region, and have a professional perform any flush or refill if you’re unsure.
