The 2015 Chevy Cruze uses Dex-Cool orange long-life coolant, GM’s extended-life formulation.
In practical terms, the Cruze relies on Dex-Cool for corrosion protection and extended service intervals. You’ll typically use Genuine GM Dex-Cool or a GM-approved Dex-Cool-compatible coolant, available as premixed 50/50 or as concentrate that must be diluted with distilled water. Avoid mixing Dex-Cool with green or non-Dex alternatives, and follow the maintenance schedule in the owner's manual for replacement intervals.
Dex-Cool in the Cruze
Dex-Cool basics
Dex-Cool is an orange, HOAT-style extended-life coolant used by General Motors. It protects aluminum components and is designed for longer service life than conventional greens.
Key characteristics and guidelines for using Dex-Cool in the Cruze:
- Color and technology: Orange Dex-Cool, a HOAT extended-life coolant compatible with GM engines.
- Availability: Sold as premixed 50/50 or as concentrate that must be diluted with distilled water to achieve 50/50 strength.
- Compatibility: Use only Dex-Cool or a GM-approved Dex-Cool-compatible coolant; do not mix with green or other non-Dex coolants.
- Service life: Typically rated for about 5 years or 150,000 miles, though always follow the manual and local conditions.
- GM designation: Look for labeling that states Dex-Cool or GM Dex-Cool-compatible; verify product compatibility with your vehicle’s specification.
Using Dex-Cool correctly helps prevent corrosion, deposits, and overheating issues in the Cruze’s cooling system.
Maintenance and topping off
Guidelines for topping off, replacement intervals, and safe handling:
- Make sure the engine is cool before opening the radiator cap or reservoir to avoid scalding from pressurized coolant.
- Inspect the coolant level in the reservoir when the engine is off and cold; if low, top with the same Dex-Cool product you use for the rest of the system.
- If you need to replace or flush the system, use Dex-Cool or a GM-approved Dex-Cool-compatible coolant, and consider a complete flush if mixing has occurred.
- Do not mix Dex-Cool with traditional green coolant; mixing can reduce effectiveness and cause deposits.
- For concentration, mix with distilled water to achieve a 50/50 solution if using concentrate; premixed bottles are ready to go.
- Record the service date and mileage on maintenance logs and follow the owner's manual maintenance schedule or GM guidance for replacement intervals.
For many Cruze owners, a professional flush and fill at a service center is recommended if you are unsure about the system’s current condition or mixing history.
