The Chevy Traverse typically uses Dex-Cool orange extended-life antifreeze, usually in a 50/50 mix with distilled water. Always confirm the exact specification for your model year in the owner’s manual or with a dealership, as there can be year-by-year differences.
For most Chevy Traverses, the recommended coolant is Dex-Cool, a HOAT (Hybrid Organic Acid Technology) formulation designed by GM for their engines. It is sold in orange color and is intended to provide extended protection when used as directed. Do not mix Dex-Cool with traditional green (silicate-based) coolant or with other brands unless the label explicitly states compatibility. If you’re unsure about your vehicle’s requirements, consult the manual or a GM-certified technician.
Understanding the Dex-Cool requirement for the Traverse
Dex-Cool orange HOAT formulation
Dex-Cool is GM’s extended-life coolant, typically orange in color. It is designed to protect cooling system components over a longer period than conventional coolants, and it’s commonly specified for Chevrolet SUVs, including the Traverse, across many model years. Use Dex-Cool unless your owner’s manual specifies a different requirement.
Mixing, dilution, and compatibility
Most Traverses use a 50/50 mix of Dex-Cool coolant and distilled water. Ready-to-use (pre-diluted) Dex-Cool is also available. Do not mix Dex-Cool with green, blue, or universal coolant unless the product label states it’s compatible with Dex-Cool; improper mixing can reduce protection and potentially cause gelling or sludge buildup.
What to buy and how to prepare
Before you shop or work on the cooling system, here are the types of Dex-Cool options you’ll commonly encounter and how they’re used.
- Dex-Cool Extended Life Antifreeze/Coolant (orange), HOAT, GM-approved for most Traverses.
- Dex-Cool Ready-To-Use (50/50) pre-diluted in an orange bottle for direct pouring.
- Dex-Cool Concentrate (to be mixed with distilled water to achieve 50/50), for select service scenarios.
When purchasing, ensure the product explicitly states it is Dex-Cool and meets GM specification for Dex-Cool. If a store carries generic “orange” coolant, verify it is Dex-Cool or GM-approved before purchasing.
Steps to top up, replace, or flush Dex-Cool on a Traverse
Below are practical steps to follow if you’re adding coolant, draining and replacing, or performing a coolant flush. These steps assume normal, engine-coolant service as described in typical vehicle maintenance guides.
- Park on a level surface, turn off the engine, and let it cool completely before opening the hood.
- Locate the radiator reservoir and radiator drain valve. Have a drain pan ready to catch old coolant.
- Carefully remove the radiator cap (when cool) and drain the system if performing a full flush or replacement.
- Flush the cooling system if you notice sludge, debris, or after a complete coolant exchange, following proper dealer guidance or a service manual.
- Pour in Dex-Cool (50/50 mix with distilled water if using concentrate) until the reservoir reaches the “MAX” line, then start the engine with the cap off briefly to purge air.
- Replace the cap, run the engine to operating temperature, and recheck for leaks and the coolant level; top up as needed.
- Dispose of old coolant responsibly at a recycling center or automotive shop; never pour it down the drain.
Note: If your Traverse’s manual specifies a non-Dex-Cool coolant or a different mixture ratio, follow that guidance precisely. If you’re unsure or uncomfortable performing cooling system work, seek service from a GM-certified technician.
Summary
In most Chevy Traverse models, the recommended antifreeze is Dex-Cool orange extended-life coolant (a GM HOAT formulation), typically used in a 50/50 mix with distilled water. Always verify the exact specification for your year and engine by checking the owner’s manual or consulting a dealer. Do not mix Dex-Cool with non-Dex-Cool or green coolants, and dispose of old coolant properly. For routine topping up, ready-to-use Dex-Cool 50/50 is convenient, but ensure it matches the vehicle’s specifications.
What color antifreeze does a Chevy Traverse take?
What color coolant does Chevy Traverse use? It's critical to understand that color doesn't matter. While most Organic Acid Technology (OAT) coolants are normally orange, yellow, red or purple, Hybrid Organic Acid Technology (HOAT) coolants are orange and yellow.
