Product Information

Full details

The VAICO V30-1373 Washer Tank Sealing Cap is an essential maintenance component for Mercedes-Benz owners looking to secure their washer fluid reservoir. Designed as a direct, high-quality alternative to original equipment (OE), this cap ensures a leak-free seal for non-heated fluid systems. While it provides excellent reliability and durability, users must verify that their vehicle does not require a heated washer fluid setup before installation.

FAQs

Does this cap fit heated washer systems?

No, the V30-1373 is specifically designed for non-heated washer fluid systems.

Which OE numbers does this part replace?

It replaces OE numbers 1248690272 and A1248690272.

Is this a genuine Mercedes-Benz part?

No, this is a high-quality aftermarket replacement part manufactured by VAICO.

How do I know if this fits my vehicle?

Please verify your vehicle's specific OE part number against the ones provided or check your chassis model (W169, W245, etc.) to ensure compatibility.

What is the primary function of this cap?

Its primary function is to seal the washer fluid reservoir to prevent leakage, spills, and the ingress of dirt or debris.

Troubleshooting

Cap will not stay sealed or feels loose

Check the reservoir filler neck for plastic burrs or deformation. If the neck is damaged, the cap may not seat properly.

Fluid leaking around the cap area

Ensure the cap is fully threaded or pressed down until it reaches the end of its travel. Verify that the rubber gasket is intact and clean.

Pros and Cons

Pros

  • Matches exact OE specifications for a perfect fit
  • Prevents fluid leakage and debris entry
  • High-quality construction from a trusted aftermarket brand
  • Compatible with numerous classic and modern Mercedes-Benz models

Cons

  • Not compatible with heated washer fluid systems
  • Requires manual verification of OE part number for fitment accuracy
  • May be difficult to seat if the original reservoir neck is deformed

Setup, Compatibility & Care

To install the cap, simply remove the old unit by twisting it counter-clockwise and clearing away any debris from the reservoir neck. Press or screw the new VAICO V30-1373 firmly into place until it clicks or seats securely. Ensure you confirm that your specific vehicle chassis (e.g., W169, W202) is supported and that your reservoir is not part of a heated assembly. For care, inspect the cap every time you refill your washer fluid; if it appears loose or the seal shows signs of cracking, it should be replaced immediately to prevent debris from entering the pump system.
