The 2018 Chevy Trax uses GM Dex-Cool, an orange long-life antifreeze designed for GM engines; the standard practice is a 50/50 mix with distilled water. Use a GM-approved Dex-Cool product and avoid mixing with other coolant types.
Below is a detailed guide on the coolant type for the Trax, how to mix it, and maintenance considerations to keep the cooling system in good shape.
Recommended coolant for the 2018 Trax
GM specifies Dex-Cool (orange, OAT) as the official coolant for this model. Using the wrong type can lead to compatibility issues and reduced protection against corrosion.
- Use GM Dex-Cool or another GM-approved orange OAT coolant that meets GM specifications for Dex-Cool compatibility.
- Avoid traditional green (IAT) or HOAT/Silicade-based coolants not approved by GM.
- Look for labeling that confirms Dex-Cool compatibility and GM suitability.
Sticking with Dex-Cool helps protect the cooling system components such as the water pump, radiator, and intake gaskets, which are designed to work with this chemistry.
Mixing, replacement schedule, and maintenance
Before any refill, know the recommended dilution and service interval. For the Trax, Dex-Cool is used in a 50/50 mix with distilled water unless a pre-diluted product is specified by the label or manual.
- Mix ratio: 50% Dex-Cool, 50% distilled water. If buying pre-diluted Dex-Cool, ensure it is the 50/50 product and suitable for GM cars.
- Do not mix Dex-Cool with non-GM coolants or with green coolant; mixing can cause sludge or reduced protection.
- Check coolant level with the engine cold; use the reservoir markings to stay within the Full/Low range.
- Typical replacement interval for Dex-Cool is about 5 years or 150,000 miles, depending on driving conditions and local GM recommendations. Refer to the owner’s manual for the exact interval.
For any coolant service, it’s wise to have a professional perform a system flush if switching from a non-Dex-Cool to Dex-Cool or if sludge or contamination is suspected.
Practical tips for owners
Ensure you purchase the correct Dex-Cool product labeled for GM vehicles, and have the technician confirm the system is sealed and free of leaks. Regular checks on the coolant level and clarity help prevent overheating and corrosion damage.
Summary
The 2018 Chevrolet Trax uses GM Dex-Cool, an orange long-life coolant (OAT). Use a 50/50 mix with distilled water unless your product is pre-diluted, never mix with incompatible coolants, and follow GM’s maintenance schedule for replacement to keep the cooling system reliable.
