What type of coolant should you use in place of Dexcool?

If you're looking to replace Dexcool, it's recommended to use an approved organic acid technology (OAT) coolant that is compatible with aluminum engines and radiators. A universal coolant that meets the ASTM D6210 specification can also be a suitable alternative. Always check the manufacturer’s specifications for your vehicle to ensure compatibility and avoid mixing different types of coolants, as this can lead to corrosion and performance issues.
