The 2014 Chevy Cruze uses Dex-Cool extended-life coolant (orange), GM-approved, typically sold as a 50/50 premixed solution. It should be used as designed and not mixed with non–Dex-Cool formulas.
Dex-Cool in the Cruze: what you need to know
What Dex-Cool is
Dex-Cool is GM’s ethylene glycol–based extended-life coolant. It is formulated to protect the cooling system from corrosion and overheating for a longer period than conventional green coolant. For the Cruze, GM generally specifies Dex-Cool as the coolant choice across the engine options available in 2014.
Color and forms
Dex-Cool for the Cruze is typically orange in color and is available as a premixed 50/50 solution or as a concentrate that you dilute with distilled water to reach the same 50/50 mix. Always use a GM-approved Dex-Cool product or a coolant labeled as Dex-Cool-compatible for GM vehicles. Do not mix Dex-Cool with conventional green coolant or with other non–Dex-Cool formulations, as mixing can cause cooling issues and potential damage.
Before you shop for coolant or plan a service, here are the essentials to ensure you stay within GM specifications.
- Dex-Cool Extended Life coolant (orange), GM-approved
- Premixed 50/50 or concentrate to be diluted with distilled water
- Avoid mixing with green or non–Dex-Cool coolants
- Follow the replacement interval: typically around 5 years or 150,000 miles, whichever comes first
Bottom line: Use only Dex-Cool-compatible products and adhere to GM’s service intervals to protect the Cruze’s cooling system.
Maintenance and service guidance for the Cruze cooling system
Proper handling during topping off, drain-and-fill, or a full flush helps prevent contamination and cooling-system damage. The steps below outline common practices aligned with GM recommendations for the Cruze.
- Park on a level surface and ensure the engine is completely cool before opening the radiator cap or drain valves.
- If performing a drain-and-fill, drain the old coolant from the radiator and engine, then close the drain and refill with Dex-Cool (premixed 50/50) or Dex-Cool concentrate diluted with distilled water to the same ratio.
- Bleed the cooling system according to the owner’s manual to remove air pockets that can cause overheating or hot spots.
- Check for leaks and verify the coolant level after the engine reaches operating temperature and cools back down to normal temperatures.
- Consider a full system flush if the coolant is degraded, contaminated, or you are changing from a different coolant type; use a GM-approved flush product and follow the directions.
Bottom line: Regular checks and proper bleeding plus using Dex-Cool as directed will help maintain the Cruze’s cooling system and prevent corrosion or overheating.
Summary
For a 2014 Chevrolet Cruze, the recommended coolant is Dex-Cool Extended Life (orange). Use GM-approved Dex-Cool, preferably the 50/50 premixed version or concentrate diluted with distilled water to a 50/50 mix. Do not mix Dex-Cool with other coolant types, and follow the official maintenance interval (generally 5 years or 150,000 miles). If you’re unsure which coolant is in your car, consult a GM dealer or a qualified mechanic to confirm and avoid cross-contamination. Regular monitoring, proper bleeding, and a correct fill will help keep the engine cool and protected.
