GMC Terrain: Vehicle Checks / Washer Fluid

What to Use

When windshield washer fluid is needed, be sure to read the manufacturer's instructions before use. If operating the vehicle in an area where the temperature may fall below freezing, use a fluid that has sufficient protection against freezing.

Adding Washer Fluid

GMC Terrain. Washer Fluid

Open the cap with the washer symbol on it. Add washer fluid until the tank is full. See Engine Compartment Overview for reservoir location.

Caution

  • Do not use washer fluid that contains any type of water repellent coating. This can cause the wiper blades to chatter or skip.
  • Do not use engine coolant (antifreeze) in the windshield washer. It can damage the windshield washer system and paint.
  • Do not mix water with ready-to-use washer fluid. Water can cause the solution to freeze and damage the washer fluid tank and other parts of the washer system.
  • When using concentrated washer fluid, follow the manufacturer instructions for adding water.
  • Fill the washer fluid tank only three-quarters full when it is very cold. This allows for fluid expansion if freezing occurs, which could damage the tank if it is completely full.
