TOPRAN 502 474 Windshield Washer Nozzle – OE

There’s a specific kind of frustration that comes from hitting the washer stalk on the highway and watching fluid go everywhere except the windshield. This listing is for the TOPRAN windshield washer nozzle (manufacturer part 502 474), bonnet 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 bonnet 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:

• Is manufactured to the tolerances the vehicle left the factory with, not a generic universal-fit compromise
• Restores the factory spray pattern, so fluid lands on the glass instead of the hood or the A-pillar
• Clears road film, bug strikes, and winter road salt in the first pass instead of smearing it across the glass
• Seats into the factory mounting point without trimming, filing, or improvising a bracket
• Matches the original fluid channel diameter, so pump pressure and spray volume stay within factory spec
• Holds up to UV exposure and temperature swings without the nozzle body going brittle and cracking

Who This Part Is For

• Anyone doing a full wiper-and-washer service alongside new blades and fresh washer fluid.
• Owners dealing with a nozzle that sprays off-target after a body shop repair or hood replacement.
• DIY mechanics working from a used-car pre-purchase inspection checklist that flagged a dead jet.
• Fleet and shop technicians stocking OE-spec replacements for routine washer system service.

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.

TOPRAN is a German aftermarket brand with one of the broadest small-parts catalogs in the industry, and this part is sold as new, unused stock.

Frequently Asked Questions

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.

Is this an OEM part or an aftermarket part?

This is manufactured to OE specification by an aftermarket supplier, matching the fit, material, and performance of the original equipment part without carrying the vehicle manufacturer’s brand name or price premium.

What makes this washer nozzle different from a universal-fit replacement?

It’s manufactured to the original part number’s exact specification, meaning bore diameter, thread pitch, and mounting geometry match what the vehicle left the factory with. A universal nozzle can physically fit into the hole and still spray at the wrong angle or pressure because the internal channel geometry is different.

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.
