Adding Windshield Washer Fluid – Step-By-Step Instructions

The following are the steps for adding windshield washer fluid.

Step 1: Pop the Hood and Prop It

The first step is to pop the hood. Find the hood release latch under the steering wheel and give it a pull to release the hood. Now go to the front of the  vehicle and reach under the slightly popped hood. There is a latch there, near the center. Press that latch upward to release the hook. Once you have the hood up, prop it up with the prop rod located on the left side of the engine bay as you stand in front of the vehicle looking at the engine. Fit the prop rod into the hole in the underside of the hood designed for this purpose.

Step 2: Locate the Windshield Washer Fluid Reservoir

This question comes up a lot:

Where is the washer fluid reservoir for the rear windshield wiper?

The answer is that the Toyota Sienna has only one windshield washer fluid reservoir for both the front and the rear wipers. It is located under the hood on the left side of the engine bay as you face the vehicle from the front.

Locate the windshield washer fluid reservoir on the left, and obtain a bottle of windshield washer fluid.


Open the cover on the reservoir by pulling up on the right side of  the black cover to flip it up.


Step 3: Pour in the Fluid

Now, carefully pour in the fresh windshield washer fluid.


Continue pouring fluid into the reservoir until it is full. You know it is full when you can see the fluid through the plastic. Fill it to about an inch or 2 from the top.

The final step is to snap the black cover closed. Make sure you hear a ‘click’ when it snaps back into place.
