Century V6-3100 3.1L VIN M SFI (1998)
Coolant: Description and Operation
GM Goodwrench DEX-COOL was developed in order to last for 240,000 km (1150,00 miles) or 5 years, whichever occurs first. Follow the
instructions in Draining and Filling Cooling System. Use only GM Goodwrench DEX-COOL(R) or HAVOLINE(R) DEX-COOL when adding or
changing the coolant.
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).
A 50/50 mixture of ethylene glycol DEX-COOL(R) and 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.
