NCSW8005L
Product Information
Product Information
Screenwash Summer 5L, Green.

The NAPA Summer Screenwash 5L NCSW8005L is a seasonal windscreen cleaning fluid formulated to help keep vehicle glass clean and clear during warmer weather. Supplied in a convenient 5-litre container with a green formulation, it is designed for use in the vehicle's windscreen washer system to tackle everyday summer contamination and maintain good visibility.

Summer driving can quickly leave the windscreen covered with insects, road grime, dust and traffic film. Using a dedicated screenwash rather than plain water provides improved cleaning performance, helping the washer and wiper system remove deposits more effectively.

What This Product Does:
Screenwash is stored in the vehicle's washer reservoir and delivered through the washer jets onto the windscreen when the washer system is activated.

Working together with the windscreen wipers, NAPA Summer Screenwash helps loosen and remove contamination from the glass, improving visibility without requiring the driver to stop and manually clean the windscreen.

During summer, it is particularly useful for dealing with common contaminants such as:

  • Insect residue
  • Road grime
  • DustTraffic film
  • General dirt and deposits
  • Light greasy contamination

Keeping the windscreen clean also allows the wiper blades to work more effectively, providing the driver with a clearer view of the road.

Symptoms Of Wear Or Failure:
Screenwash is a consumable rather than a component that mechanically wears out. Regular checks are therefore important, particularly before long journeys or periods of frequent driving.

Common signs that the washer system needs attention include:

  • Low or empty washer reservoir
  • Little or no fluid reaching the windscreen
  • Windscreen remaining dirty after using the washers
  • Increased smearing when operating the wipers
  • Difficulty removing insect residue and road grime
  • Washer fluid becoming dirty or contaminated
  • Plain water being used instead of an appropriate screenwash
  • Washer warning light appearing on equipped vehicles

If the reservoir contains sufficient fluid but nothing reaches the windscreen, the washer pump, hoses and jets should also be inspected for faults or blockages.

Why Replacement Matters:
A clean windscreen is essential for clear visibility and safer driving. Dirt, insects and traffic film can reduce visibility, particularly when driving towards low sunlight or when glare from headlights and street lighting reflects from a contaminated windscreen.

Using a suitable screenwash helps remove these deposits more effectively than relying on water alone.

Regular use can help:

  • Maintain clearer windscreen visibility
  • Remove stubborn summer contamination
  • Reduce dirt and traffic film
  • Improve washer and wiper effectiveness
  • Make insect residue easier to remove
  • Keep the windscreen cleaner between manual washes

Maintaining an adequate level of screenwash also ensures the washer system is ready when visibility suddenly becomes compromised while driving.

Diagram ref no 16

This grommet is often replaced during washer system service, reservoir removal, pump replacement, or restoration of classic Porsche vehicles where the original rubber has deteriorated over time.

The washer pump grommet creates a watertight seal between the washer pump and the reservoir or body opening, preventing fluid leaks and contamination. Its flexible rubber construction also absorbs pump vibration, reducing noise and mechanical stress, helping the windscreen washer system operate smoothly, quietly, and reliably.

Over time, original washer pump grommets can become brittle, cracked, shrunken, or deformed due to exposure to heat, ozone, washer fluid, and age. A compromised grommet may allow washer fluid to leak, pump vibration to increase, or even cause corrosion or damage to surrounding bodywork. Replacing worn grommets with Genuine Porsche OE ensures proper sealing, preserves vehicle integrity, and maintains original equipment performance and quiet operation.

When to replace:
•  Washer fluid leaks around the pump area
•  Original grommet is cracked, hardened, or visibly deteriorated
•  Washer pump has been removed for service
•  During restoration or bodywork involving the washer reservoir
•  To resolve pump noise or vibration issues

The washer pump grommet provides stable support and isolation for the windscreen washer pump. It helps maintain a proper seal around the pump housing, preventing washer fluid leaks, reducing vibration and noise, and ensuring the pump operates reliably.

The original rubber grommet can become hardened, cracked, or brittle with age and exposure to heat, fluids, and ozone. A degraded seal may allow washer fluid to leak, introduce contaminants into the washer reservoir or bodywork, and cause pump vibration or noise. Replacing it with an OE Match grommet restores a tight, flexible seal and improves washer system reliability and quiet operation - especially important on older Porsche vehicles where original components are no longer supple.

When to replace:
•  Washer fluid leaks at the pump mounting point
•  Grommet feels cracked, stiff, or swollen
•  Washer system is noisy or vibrates excessively
•  During washer pump replacement or bodywork restoration
•  Preventive service on high-mile classic Porsches

About Washer pumps / bottles / jets

Washer Pumps, Washer Bottles & Washer Jets – Clear Vision for Every Drive

Washer pumps, bottles, and jets are key components of your Porsche’s windscreen cleaning system. They work together to deliver washer fluid from the reservoir through the pump and jets, keeping your windscreen clear of dirt, bugs, and debris for safe driving visibility in all conditions.

At Design911, we supply a comprehensive range of genuine and high-quality washer system components - including washer bottles (reservoirs), electric washer pumps, and precision spray jets — for all Porsche models such as the 911, Boxster, Cayman, Cayenne, Macan, and Panamera. Every part is designed to offer high levels of fitment and performance for dependable cleaning power and long-term reliability.

What Do Washer Pumps, Bottles and Jets Do?

  • Washer Bottle / Reservoir: Stores the washer fluid and is typically located in the engine bay or boot area.
  • Washer Pump: An electric motor that pressurises the fluid and pushes it through the lines toward the 
  • Washer Jets / Nozzles: Deliver a fine, even spray of fluid onto the windscreen or headlights for effective cleaning coverage.

Together, these components ensure your windscreen remains clean and streak-free, maintaining visibility and safety in all weather conditions.

Why Do Washer Components Fail?
Over time, washer system parts can degrade or fail due to wear, contamination, or environmental exposure. Common causes include:

  • Pump failure due to internal corrosion or debris blocking the impeller.
  • Leaking washer bottles from cracks, freezing, or age-related wear.
  • Clogged jets caused by limescale, dirt, or poor-quality washer fluid.
  • Electrical issues such as damaged wiring or corroded connectors.
  • Perished hoses or seals leading to fluid leaks and reduced pressure.

Symptoms of failure include weak or no spray from the jets, fluid leaks, or a pump that doesn’t activate when the washer stalk is used.

Why Replace Faulty Washer Components?

A properly functioning washer system is essential for visibility and road safety. Replacing worn or damaged components ensures your windscreen remains clean and clear in all driving conditions.

Benefits of replacement include:

  • Restored washer performance and pressure.
  • Improved visibility and safety in rain or road spray.
  • Prevention of leaks and electrical damage.
  • High-quality parts for perfect fitment and durability.
