NISSAN 28913-JM01A Windshield Washer Reservoir Cap

The genuine NISSAN (SKU: 28913-JM01A) windshield washer reservoir cap is a premium quality, original equipment manufacturer (OEM) component that ensures proper sealing of the washer fluid reservoir. This small yet critical component prevents dirt, dust, and other foreign contaminants from entering the washer system, thereby protecting the washer pump and spray nozzles from clogging and premature failure.

Technical Characteristics and Specifications:

• Manufacturer: NISSAN (Genuine OEM part)
• Part Name: Windshield Washer Reservoir Cap (CAP)
• Material: High-grade, heat- and chemical-resistant polypropylene (PP) plastic engineered to withstand engine bay temperature fluctuations and alcohol-based washer fluids.
• Design: Snap-on closure equipped with a flexible retaining strap to prevent loss of the cap during fluid refills.
• Mounting Location: Fits directly onto the filler neck of the windshield washer fluid reservoir.

Function and Signs of Failure:

The washer reservoir cap acts as a primary barrier of defense. If the cap becomes damaged, lost, or aged, the following issues may occur:

• Contaminant Ingress: Dust, sand, or debris can enter the reservoir, clogging spray nozzles or damaging the electric pump impeller.
• Evaporation and Spillage: In the absence of a proper seal, washer fluid evaporates faster or can splash into the engine bay during vehicle vibration and cornering.
• Material Fatigue: Due to engine heat and environmental exposure, plastic becomes brittle over time, resulting in cracking and broken retaining straps.

Choosing a genuine NISSAN part guarantees perfect dimensional accuracy, OEM fitment, and long service life, ensuring the trouble-free operation of your windshield washer system.
