The 2019 Chevy Traverse uses Dex-Cool, GM’s orange long-life coolant, or a Dex-Cool-compatible alternative. Typically, it should be mixed 50/50 with distilled water unless you’re using a pre-diluted version.
The 2019 Traverse is equipped with a cooling system designed for Dex-Cool, a specific orange-colored coolant from General Motors. Using the correct Dex-Cool product helps prevent corrosion and overheat issues, and sticking to a compatible formulation is important for warranty and performance. Below is a concise guide to selecting and using the right coolant for this vehicle.
Coolant type and compatibility
Before you refer to a list of guidelines, note the essential points about what to use and what to avoid in your Traverse’s cooling system.
Dex-Cool and compatibility basics
Before the following list, here are the key points: use Dex-Cool long-life coolant or another product explicitly labeled as Dex-Cool-compatible that meets GM specifications. Do not mix Dex-Cool with non-Dex-Cool types, and avoid using traditional green or universal coolants without verifying Dex-Cool compatibility.
- Use Dex-Cool long-life coolant (orange) or a Dex-Cool-compatible coolant that meets GM specifications.
- Do not use green, blue, or other non-Dex-Cool coolants unless they are explicitly labeled as Dex-Cool-compatible.
- Fill the system with a 50/50 mix of Dex-Cool coolant and distilled (or demineralized) water, unless you are using a premixed 50/50 Dex-Cool product.
- If the system was previously filled with a different type of coolant, flush the system before topping off with Dex-Cool to prevent incompatibility or sludge buildup.
- Follow the product label for exact mix ratios and use the recommended concentrate or premixed option.
- Check for any GM-specific requirements or service bulletins regarding Dex-Cool use for your particular engine and VIN.
When in doubt, consult your owner's manual or a GM-certified technician to confirm the exact Dex-Cool specification and fill procedure for your vehicle.
Mixing ratios and practical tips
Practical guidance accompanies the list to ensure correct mixing and maintenance of the cooling system.
Summary of practical steps: aim for a clean, 50/50 Dex-Cool and distilled water mix, verify the color is orange (not contaminated or diluted with other colors), and perform a proper flush if the old coolant is unknown or incompatible. Use OEM-recommended products to support warranty and engine longevity.
Summary
In short, the 2019 Chevy Traverse takes Dex-Cool (orange) long-life coolant or a Dex-Cool-compatible alternative that meets GM specifications. Use a 50/50 mix with distilled water unless you have a premixed Dex-Cool product, avoid mixing with other coolant types, and follow GM guidance or consult a dealer if unsure.
