Notice: Antifreeze can be added to raise the boiling point of the
coolant, but too much will affect the freezing point. Do not use a solution
stronger than 70 percent antifreeze, as the freeze level rises rapidly
after this point. Pure antifreeze will freeze at -22°C (-8°F).
This vehicle as a newly developed engine coolant. GM Goodwrench
DEX-COOL® was developed in order to last for 240,000 km (150,000 miles)
or 5 years, whichever occurs first. Follow the instructions in Draining
and Filling Cooling System. Use only GM Goodwrench DEX-COOL® or HAVOLINE®
DEX-COOL® when adding or changing the coolant.
A 50/50 mixture of ethylene glycol DEX-COOL® and clean drinkable
water will provide the following protection:
• | Give freezing protection down to -37°C (-34°F) |
• | Give boiling protection up to 129°C (265°F) |
• | Protect against rust and corrosion |
• | Help keep the proper engine temperature |
• | Let the warning lights and gauges work as they should. |
