Coolant: Service Precautions

CAUTION: When adding coolant, it is important that you use GM Goodwrench DEX-COOL coolant. If coolant other than DEX-COOL is added to the system the engine coolant will require change sooner at 50,000 km (30.000 miles) or 24 months.

Do not use a solution stronger than 70 percent antifreeze. Pure antifreeze will freeze -22°C (-8°F).
