Step 1

Step 2

Locate the Reservoir

  • Release the latch of your car’s hood and hold it open with the hood prop rod.
  • Look for the wiper fluid reservoir fill cap (see photo). It could be on either side of the engine compartment near the front fenders, but sometimes it’s at the back near the base of the windshield.

Step 3

Fill It Up

  • Pop the cap open and pour the wiper fluid directly into the reservoir until it is full — a funnel works well for this. Most reservoirs hold one gallon of wiper fluid.
  • Close the cap tightly, reset the hood prop rod and gently close the hood.
