Water Tank Reservoir Cap And Hose.
The OE MATCH Water Tank Reservoir Cap And Hose is a replacement assembly for the vehicle's windscreen washer reservoir system.

Fits:
  • Porsche 911 1968 2.0L
  • Porsche 911 1968-1973 2.7L RS LWB (F)  

Diagram Ref No 2

The assembly provides the reservoir closure together with the associated hose connection required for correct operation of the washer-fluid system. The cap helps keep the washer reservoir securely closed, while the hose forms part of the fluid delivery arrangement between the reservoir and washer system.

Age, heat, repeated servicing and exposure to washer fluid can cause older plastic and rubber components to harden, crack, split or lose their sealing ability. Replacing a deteriorated cap and hose helps prevent washer-fluid leakage and supports dependable windscreen washer operation.

What This Product Does:
The OE MATCH Water Tank Reservoir Cap And Hose forms part of the windscreen washer-fluid storage and delivery system.

The reservoir cap helps:

  • Close the washer-fluid reservoir
  • Protect the reservoir opening
  • Reduce contamination entering the tank
  • Maintain the correct washer-system arrangement
  • Prevent fluid escaping through an incorrectly sealed opening

The associated hose provides a fluid pathway within the washer system, allowing washer fluid to be transferred from the reservoir towards the relevant washer components.

Together, these components help ensure that washer fluid remains contained and available when the windscreen washers are operated.

Symptoms Of Wear Or Failure:
Possible signs of cap deterioration include:

  • Cap no longer fitting securely
  • Loose reservoir cap
  • Cracked or damaged cap
  • Hardened or brittle plastic
  • Damaged sealing surfaces
  • Washer fluid leaking around the reservoir opening
  • Cap repeatedly becoming detached
  • Visible age-related deterioration
  • Dirt or debris entering the reservoir

An insecure or damaged cap can leave the washer reservoir exposed to contamination and may allow fluid to escape.

Why Replacement Matters:
Replacing a deteriorated OE MATCH Water Tank Reservoir Cap And Hose helps maintain a dependable windscreen washer system.

Replacement can help:

  • Prevent washer-fluid leakage
  • Maintain washer-fluid supply
  • Restore secure reservoir closure
  • Protect the reservoir from contamination
  • Restore deteriorated hose connections
  • Support consistent washer-fluid delivery
  • Maintain effective windscreen cleaning
  • Preserve clear driver visibility
  • Restore the washer system's correct appearance and arrangement

Although relatively simple components, the cap and hose contribute directly to the reliability of the windscreen washer system.

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.
