The Cruze typically uses Dex-Cool, GM’s orange extended-life coolant, in a 50/50 mix with distilled water or a pre-diluted 50/50 solution. Always verify the exact specification for your year and engine in the owner's manual before buying or opening the cooling system.
Dex-Cool: The standard choice for the Cruze
For most Cruze models, Dex-Cool or a GM-approved equivalent is recommended. This orange, long-lasting coolant is designed for the Chevrolet cooling system and helps prevent corrosion and freezing. Do not mix Dex-Cool with traditional green coolant unless GM explicitly approves a Dex-Cool-compatible universal product.
- Dex-Cool (orange) long-life coolant, or a GM-approved equivalent that meets GM DS-1/Dex-Cool specifications.
- Prepare the coolant to a 50/50 mix with distilled water, or purchase pre-diluted 50/50 Dex-Cool.
- Avoid mixing Dex-Cool with green or other non-GM coolants, as mixing can reduce performance and cause corrosion or deposits.
- Always confirm the exact specification for your Cruze's year/engine in the owner's manual or at a Chevrolet dealer.
- If performing a full cooling-system flush, use a Dex-Cool-compatible flush product and refill with Dex-Cool or a GM-approved equivalent.
In short, Dex-Cool or a GM-approved Dex-Cool-equivalent is typically the right choice for the Cruze. Follow your manual for the correct ratio and replacement intervals, and avoid mixing with non-Dex-Cool formulations unless GM approves it.
Model-year caveats
While Dex-Cool covers the Cruze broadly, certain markets or engine configurations may have specific requirements. If you own a Cruze from a different region or a unique engine variant, consult the manual or a Chevrolet service advisor to confirm the exact coolant specification for your vehicle.
Maintenance and service tips
To keep the cooling system healthy, follow these guidelines for topping up and maintenance.
- Check the coolant level when the engine is cold and top up with the same Dex-Cool coolant if needed; never top up with a different type of coolant.
- Use distilled water for any mixing; avoid tap water, which can introduce minerals that cause buildup.
- Do not open the radiator cap when the engine is hot to avoid scalding; relieve system pressure only when cold.
- Typically replace Dex-Cool every 5 years or 150,000 miles, whichever comes first; verify the interval in your manual for your specific model/year.
- If the coolant shows contamination or the vehicle overheats, have a professional flush and refill with the correct Dex-Cool product.
- Dispose of used coolant responsibly at a recycling center or auto shop that accepts hazardous fluids.
Regular checks and using the correct Dex-Cool formulation help prevent overheating and engine damage. When in doubt, rely on a dealership or qualified mechanic for coolant changes.
Summary
For most Chevrolet Cruze models, the recommended coolant is Dex-Cool (orange) or a GM-approved equivalent, used in a 50/50 mix with distilled water. Do not mix Dex-Cool with green or other non-GM coolants unless explicitly approved. Always consult the owner's manual or a dealer for your exact year/engine and replacement interval, and dispose of old coolant properly.
