The Chevy Cruze generally uses Dex-Cool, GM’s orange long-life coolant (an OAT formulation). In most cases you should use GM Dex-Cool or a GM-approved Dex-Cool-compatible coolant.
Understanding the Cruze’s coolant requirements
Dex-Cool is designed for aluminum engines and cooling systems used by GM. It provides longer service life and protection against corrosion. Using the wrong type can reduce cooling efficiency and cause deposits or corrosion within the cooling system.
What to use in a Cruze
To confirm your vehicle’s exact specification and to purchase the correct product, keep in mind these guidelines.
Choose from these options if you’re topping up or replacing the coolant in a Cruze. Each option should be GM-approved or Dex-Cool-compatible.
- GM Dex-Cool orange long-life coolant (the standard option for Cruze).
- GM-approved Dex-Cool-compatible universal coolant that explicitly states compatibility with Dex-Cool/OAT formulations.
- Pre-diluted 50/50 Dex-Cool-compatible coolant solutions that are ready to pour.
Whichever option you choose, ensure it is labeled Dex-Cool or GM Dex-Cool-compatible, and never mix with non-Dex-Cool or HOAT formulations unless the product clearly states compatibility.
How to top up or replace Dex-Cool in a Cruze
When adding or replacing coolant, follow these practical steps to avoid contamination and ensure proper mixture.
- Park the car on a level surface and let the engine cool completely before opening the cooling system.
- Check the reservoir level; if low, prepare a 50/50 mix of Dex-Cool with distilled water unless you have a pre-mixed 50/50 Dex-Cool coolant.
- Slowly add the coolant until it reaches the MAX line; replace the cap and run the engine to circulate the fluid, then recheck the level after cooling.
- Dispose of any old coolant responsibly and avoid reusing old coolant; if you’ve flushed the system, follow the manufacturer’s flush instructions.
Regular checks at service intervals help maintain cooling performance and prevent overheating or corrosion associated with Dex-Cool.
Maintenance tips and common issues
Dex-Cool offers longer life but must be kept separate from other coolant types once introduced into the system. If you observe a milky appearance, sludge, or a drop in cooling performance, consult a mechanic promptly; never drive a vehicle with suspected coolant contamination. Always reference the owner’s manual for the exact specification for your model year, as GM has updated recommendations over time.
Summary
Chevy Cruze typically uses Dex-Cool orange long-life coolant (GM Dex-Cool). Use GM Dex-Cool or a GM-approved Dex-Cool-compatible coolant, maintain a 50/50 mixture with distilled water unless a pre-mixed option is provided, and follow the maintenance schedule in your manual. If you’re unsure about the exact specification for your model year, check the manual or contact a Chevrolet dealer for confirmation.
