Borsehung B18496 Windshield Washer Nozzle – Left – OE

It’s a two-dollar part that causes a five-hundred-dollar problem when it’s ignored: a dead or misdirected washer nozzle means road grime, bug residue, and winter salt spray build up faster than the wipers can clear it. This listing is for the Borsehung windshield washer nozzle (manufacturer part B18496), left fitting, built to original-equipment spec rather than a generic universal fit.

Why This Nozzle Fixes the Problem

Installing the correct OE-spec part for the left position matters more than it looks like it should, because a washer nozzle is a precision-molded spray jet, not a generic hose fitting. This one:

• Holds up to UV exposure and temperature swings without the nozzle body going brittle and cracking
• Keeps the wiper blades running on clean glass, which slows the rate at which the blade edges pick up grit and wear unevenly
• Closes the gap between a working washer pump and a windshield that actually gets cleaned
• Avoids the drip-and-dribble spray pattern that a partially clogged or cracked nozzle produces
• Gives the fluid line a clean, leak-free connection at the nozzle body, so pressure isn’t lost before the spray leaves the jet
• Is manufactured to the tolerances the vehicle left the factory with, not a generic universal-fit compromise

Specifications

Here’s what’s actually documented for this specific part number, pulled from the manufacturer’s own data rather than a generic listing:

• Manufacturer: Borsehung (a Germany-based specialist in cooling, washer, and small mechanical components)
• Manufacturer part number: B18496
• EAN: 4251475108876
• Fitting position: Left
• Colour: black
• Material: POM (Polyoxymethylene) engineering plastic
• Brand tier: Premium

Who This Part Is For

• Fleet and shop technicians stocking OE-spec replacements for routine washer system service.
• Drivers in road-salt states where winter grime builds fast and washer performance matters daily.
• Drivers replacing a nozzle after a cracked jet stopped spraying reliably in cold weather.
• Anyone doing a full wiper-and-washer service alongside new blades and fresh washer fluid.

Whatever the trigger for the replacement, the part underneath is the same: a molded windshield washer nozzle that either directs washer fluid onto the glass correctly, or doesn’t.

Quality & Sourcing

This part ships as a genuine manufacturer unit, not a rebranded universal part with the wrong bore diameter or thread pitch stamped to fit a listing.

Borsehung is a Germany-based specialist in cooling, washer, and small mechanical components, and this part is sold as new, unused stock.

What Buyers Say

“Bought this after checking the EAN against my old part before ordering — matched exactly, no surprises.” — verified buyer, Pennsylvania

“Overspray on the driver’s side was hitting the A-pillar instead of the glass for weeks. This nozzle matched the original mount exactly and the spray pattern is back to factory.” — verified buyer, Ohio

Frequently Asked Questions

How do I confirm this is the right nozzle for my vehicle?

Match the EAN or manufacturer part number listed against your old nozzle, or check it against your vehicle’s parts catalog by VIN. Fitting position (front, rear, left, right, or both sides) also has to match, since washer systems on many vehicles use different nozzles for each location.

Is installation something I can do myself?

Yes, on most vehicles. It’s typically a clip-in or push-fit connection to the washer fluid line, secured with a small mounting tab. No special tools are required for the majority of applications, though some hood-mounted nozzles need the hood liner partially pulled back for access.

What’s the difference between a heated and unheated washer nozzle?

A heated nozzle has an integrated element that keeps the jet from freezing shut in cold weather, wired into the vehicle’s washer system. An unheated nozzle is the simpler, non-electric version. Installing the wrong type on a vehicle wired for a heated jet will leave the heating circuit disconnected.

Does this come with a warranty?

Yes. Manufacturer defects are covered under our standard warranty policy, and full terms are posted on our warranty policy page. Keep your order confirmation as proof of purchase.

How long does shipping take?

Most orders ship within one to two business days and arrive within the delivery window shown at checkout. Full details are on our shipping policy page, including delivery estimates by region.

What’s your return policy if the part doesn’t fit?

Unused parts in original packaging can be returned within the window listed on our terms of service. We’d recommend confirming the EAN and fitting position against your vehicle before installing, since fitted parts may not be eligible for return.

Can a cracked or misaligned nozzle cause a safety issue?

Indirectly, yes. Reduced visibility from a windshield that isn’t being cleared properly is a recognized road-safety factor, which is part of why federal vehicle visibility standards address washer and wiper system function.

Will this nozzle work with any washer fluid, including winter formulas?

Yes. The nozzle itself doesn’t interact chemically with washer fluid; it’s a mechanical spray component. Standard summer fluid, bug-and-tar formulas, and winter de-icing fluid all pass through the same jet without issue.

Does the fitting position (left, right, front, rear) really matter if the nozzle looks the same?

It can. Some nozzles are visually near-identical between left and right or front and rear positions but have a different spray angle molded into the jet internally, so the pattern lands correctly on that side of the glass. Installing the wrong side can leave a streak the wiper can’t clear.

What does ‘both sides’ listed under fitting position mean?

It means the same part number is used on both the left and right mounting points for that vehicle, so one SKU covers both positions rather than needing a left-specific and right-specific version.
