Washer Fluid Funnel for Tesla

A closer look

A small washer-fluid opening can be awkward to reach with a full bottle. This printed funnel is intended to provide a wider target above a compatible Tesla reservoir, helping guide the pour through a narrower outlet. It is a straightforward maintenance accessory for the moment when bottle size, surrounding trim, and access angle make refilling inconvenient. The funnel bowl has a projecting outlet; matching that outlet to the vehicle is the key selection step.

Measure the reservoir opening and the usable depth around it before ordering. Also consider whether the bottle can be held comfortably above the funnel without leaning on nearby trim. Confirm your vehicle year, filler-neck fit, and compatibility of the printed PETG part with your washer fluid before ordering, especially if the fluid contains additional cleaning or antifreeze additives. This is a removable filling aid, not a replacement reservoir cap. Remove it after filling and reinstall the vehicle's normal cap.

Useful for

• Assist with aiming a pour into a compatible washer-fluid reservoir.
• Keep a dedicated filling aid with car-care supplies.
• Make occasional top-ups easier where access to the filler neck is restricted.

Check the fit

Start with these details so you can choose the right part for your setup.

• Share your Tesla model and year, plus a photo of the washer-fluid opening.
• Measure the opening diameter and available insertion depth.
• Check the space above and around the filler neck for the funnel bowl and bottle.
• Confirm the printed PETG part is appropriate for the washer fluid you use.

What’s included

• Printed washer-fluid funnel.
• Washer fluid, reservoir cap, and other maintenance supplies are not included.

Check access with the fluid bottle in mind

The funnel's usefulness depends on more than matching the reservoir opening. Consider the size of the bottle you normally buy, where you can hold it securely and the angle needed to start the pour. Check whether the funnel bowl would leave room around the hood and surrounding trim for that movement. A larger receiving target helps only when you can keep the bottle controlled. Compare the complete approach using the vehicle's actual filler location rather than estimating access from a close photograph of the opening alone.

Measure the outlet seating area carefully

Record the filler opening and the depth available before the funnel would meet an obstruction or sit against nearby trim. Include a side view showing the angle of the filler neck. The outlet needs to guide fluid into the opening without being forced or wedged in place. Do not use a tight fit as evidence that the funnel is correctly supported. If the reservoir layout or cap arrangement differs from the reference you are comparing, share those details with the vehicle year before ordering.

Prepare a controlled refill routine

Use the washer fluid specified for your vehicle and confirm that it is suitable for contact with the printed PETG part. Start with a clean funnel so stored dust does not go into the reservoir. Follow the vehicle's filling instructions, support the bottle throughout the pour and slow down as the level approaches the appropriate point. The bowl is a guide for filling, not a container for leaving fluid to soak. Keep the ordinary reservoir cap nearby so it can be reinstalled after the funnel has been removed.

Keep the funnel clean between uses

After use, handle remaining drops in a way appropriate for the washer fluid and follow the fluid maker's cleaning and disposal guidance. Let the funnel become clean and dry before placing it in a storage area where its outlet will stay free of debris. Give it a dedicated location instead of mixing it with tools used for oils or other liquids. Inspect the bowl and outlet for damage before the next refill. Do not leave it installed under the hood or mistake it for part of the reservoir's closure.
