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.

The windscreen washer jet plays a simple but essential role in the washer system by directing washer fluid evenly onto the windscreen. This allows the wiper blades to effectively remove dirt, dust, insects and road grime, ensuring clear visibility in all driving conditions. The tall chrome design also contributes to the authentic period appearance of the front bonnet, making it an important finishing detail during any restoration.

Manufactured to OE Match standards, this replacement washer jet offers the correct fit, finish and chrome appearance, making it ideal for concours restorations, routine maintenance or replacing worn original components.

Why Do Windscreen Washer Jets Fail?

Over many years of use, washer jets are continually exposed to weather, road dirt, UV light and hard water deposits. These conditions can cause the small nozzle opening to become blocked, reducing or completely preventing washer fluid from reaching the windscreen.

The external chrome finish may also become pitted, corroded or damaged through age and exposure to the elements, detracting from the appearance of the vehicle. In some cases, accidental damage during polishing or bonnet work can bend the nozzle, affecting the spray pattern and reducing cleaning effectiveness.

As the original washer jets on many Porsche 356 models are now over sixty years old, deterioration is common even on well-maintained vehicles.

When Should They Be Replaced?

Replacement is recommended whenever the washer jet no longer produces a consistent spray pattern or shows visible signs of deterioration.

Common signs include:

  • Weak or uneven washer spray
  • Blocked or partially blocked nozzle
  • Corroded or pitted chrome finish
  • Bent or damaged nozzle
  • Washer fluid missing the windscreen
  • During concours restorations or bonnet refurbishment

Replacing tired washer jets restores both the functionality of the washer system and the authentic appearance of the vehicle.

Key Features

  • Correct tall chrome design
  • Restores effective washer fluid spray pattern
  • Improves driver visibility in poor weather
  • High-quality chrome finish
  • Precision manufactured for accurate fit
  • Ideal for restoration and routine maintenance

Benefits of Replacing the Washer Jets

  • Restores correct washer spray pattern

The bag-style reservoir was commonly used in early Porsche vehicles and is an important detail for maintaining originality. It is typically supplied with a cap and may not include internal pick-up tubes depending on version.

Constructed from durable, fluid-resistant material, it is designed to withstand long-term use while maintaining flexibility and sealing integrity.

The washer bag stores fluid and supplies it to the windscreen washer system, allowing the driver to clean the windscreen and maintain visibility.

It ensures a consistent supply of washer fluid for safe driving in dirty or wet conditions.

Function
• Stores windscreen washer fluid
• Supplies fluid to washer jets
• Maintains visibility by enabling windscreen cleaning
• Forms part of the original washer system design

Over time, original washer bags can become brittle, leak, or deteriorate due to age and fluid exposure. A damaged bag can lead to fluid loss and non-functioning washer systems. Replacing the washer bag restores proper operation and preserves the original look of the vehicle - especially important for concours or restoration projects.

When to replace
• Cracked, leaking, or perished bag
• Washer system not holding fluid
• Visible deterioration or staining
• During restoration or refurbishment
• Missing original washer reservoir

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.
