This product is acceptable for use in all vehicles that require Dex-Cool coolant and the undiluted formula means that the user can customize the concentrations of water to coolant/antifreeze for optimum performance in a range of environments.
Can coolant color be used to determine what product I can use?
No, coolant color can no longer be used to determine the correct product to add to your system because coolant suppliers no longer have common product color standards. Instead, determine what is the correct type or specification of the product you require and purchase the product with this correct specification.
Is there a specific type of antifreeze I should use in my vehicle?
Yes. See your owner’s manual or service guide for information regarding your vehicle’s fluid requirements.
Do I have to change my vehicle’s antifreeze?
Yes. Your owner’s manual or service guide will provide more information regarding vehicle-specific maintenance intervals. The maximum change interval for ACDelco Dex-Cool is 5 years, or 150,000 miles, whichever occurs first.
Is it okay to use ACDelco Traditional Coolant in my engine if it requires Dex-Cool?
No. Each vehicle is manufactured for use with a specific coolant formula. If your vehicle was not designed for use with traditional coolant/antifreeze, or coolant not recommended by your vehicle’s manufacturer, it can potentially harm your cooling system.
