The Cruze uses Dex-Cool, GM’s orange long-life coolant, typically mixed 50/50 with distilled water.
Dex-Cool and why it matters for the Cruze
Dex-Cool is an OAT (organic acid technology) coolant designed for extended service life in GM engines. It protects cooling system components from corrosion and helps prevent deposits that can affect heat transfer. For most Cruze models, Dex-Cool or an approved GM-equivalent that meets GM's specification is recommended. Do not mix Dex-Cool with other coolant chemistries.
Maintenance guidelines for your Cruze coolant
Listed here are practical steps to keep the cooling system in good shape when using Dex-Cool.
- Check the coolant level when the engine is cold; look at the reservoir markings (MIN and MAX).
- Use a 50/50 mix of Dex-Cool and distilled water, unless your owner’s manual specifies a different ratio.
- Avoid mixing Dex-Cool with green or universal coolant; if topping off is needed, use only the same Dex-Cool or a GM-approved equivalent that matches the specification.
- Follow GM’s recommended replacement interval for Dex-Cool (commonly 5 years or 150,000 miles, depending on market and model).
- When draining and refilling, perform the proper air bleed procedure to remove air pockets and ensure proper circulation.
Concluding note: Using the correct Dex-Cool type and maintaining the proper 50/50 mixture is essential to protect the Cruze’s cooling system and engine performance.
Regional variations and model-year notes
Different Cruze generations and regional markets may have slight variations in coolant specification or service intervals, so always verify against the official owner’s manual or a GM service bulletin for your exact year and region.
Where to source coolant and common pitfalls
Purchase Dex-Cool or a GM-approved OAT coolant that meets GM 6277M specifications from reputable brands. Avoid mixing in different chemistries, and don’t use standard green coolant in a Cruze that requires Dex-Cool unless your manual explicitly allows it.
Summary: For a Chevy Cruze, the standard coolant is Dex-Cool orange long-life, mixed 50/50 with distilled water, with attention to model-year and regional specifications. Following GM’s recommendations helps protect the cooling system and engine reliability.
