Washer Fluid Reservoir Cap.

The OE MATCH Washer Fluid Reservoir Cap is a high-quality replacement component designed to provide a secure closure for the windscreen washer fluid reservoir on Porsche 924 and 944 models.

Manufactured to match the original equipment fitment, this replacement cap helps keep washer fluid safely contained within the reservoir while protecting the washer system against dirt, dust and other contaminants.

Over time, original reservoir caps can become brittle, cracked, loose or damaged due to ageing, temperature changes and regular maintenance. A damaged or missing cap can allow washer fluid to escape and contaminants to enter the reservoir, potentially affecting the performance of the windscreen washer system.

The OE MATCH Washer Fluid Reservoir Cap offers a practical and cost-effective solution for restoring the correct reservoir closure, maintaining reliable washer system operation and preserving the original appearance of the engine compartment.

Ideal for routine servicing, preventative maintenance and classic Porsche restoration projects.

What This Product Does:
The washer fluid reservoir cap is an essential component of the vehicle's windscreen washer system, performing several important functions:

• Secures the Washer Fluid Reservoir: Provides a reliable closure to help prevent washer fluid from escaping during driving.
• Prevents Contamination: Helps protect the washer fluid from dirt, dust, debris and other contaminants that could enter the reservoir.
• Reduces Fluid Spillage: Minimises the risk of washer fluid splashing out of the reservoir during cornering, braking or travelling over uneven roads.
• Protects Washer System Components: Helps reduce the risk of contaminants reaching the washer pump, hoses and spray jets.
• Maintains Washer Fluid Availability: Helps retain sufficient washer fluid for effective windscreen cleaning when required.
• Maintains Original-Style Fitment: Provides a suitable replacement for the original reservoir cap, helping preserve the factory-style appearance of the washer system.

Symptoms Of Wear Or Failure:
The washer fluid reservoir cap can deteriorate over time through prolonged exposure to temperature fluctuations, ageing and regular use. Common symptoms include:

• Cracked or Split Cap: Visible cracks or fractures in the plastic material.
• Loose or Poor Fitment: The cap no longer fits securely onto the reservoir opening.
• Missing Reservoir Cap: The original cap has been lost or displaced, leaving the washer reservoir exposed.
• Washer Fluid Leakage: Fluid may spill or splash from the reservoir opening, particularly while driving.
• Brittle or Deteriorated Plastic: The cap may become hardened, discoloured or fragile with age.
• Damaged Retaining or Sealing Surfaces: Worn or distorted areas may prevent the cap from closing correctly.
• Contaminated Washer Fluid: Dirt or debris may enter the reservoir through an improperly closed opening.
• Frequent Washer Fluid Top-Ups: Unexplained fluid loss may indicate spillage from a loose or damaged cap, although leaks elsewhere in the washer system should also be checked.

Why Replacement Matters:
Replacing a worn, damaged or missing washer fluid reservoir cap is a simple but important maintenance task that helps protect the vehicle's windscreen washer system.

Key Benefits of Replacement:

• Restores a secure closure to the washer fluid reservoir.
• Helps prevent washer fluid leakage and unnecessary spillage.
• Protects the reservoir against dirt, dust and debris.
• Reduces the risk of contamination affecting the washer pump and spray jets.
• Helps maintain reliable windscreen washer system operation.
• Replaces cracked, brittle, loose or missing original caps.
• Maintains original equipment-style fitment and appearance.
• Provides a cost-effective preventative maintenance solution.
• Ideal for classic Porsche servicing and restoration.

A damaged washer fluid reservoir cap may seem like a minor issue, but maintaining a properly closed reservoir helps ensure washer fluid remains clean and available when needed.

Replacing the cap helps preserve the efficiency of the windscreen washer system, supporting clear visibility and safer driving in wet or dirty road conditions.

This grommet is used in the washer bottle / washer pump assembly on various Porsche models.

What This Part Does / Functions
•  Seals the washer pump into the washer fluid reservoir
•  Helps prevent washer fluid leaks around the pump opening
•  Supports and cushions the washer pump in the bottle
•  Helps maintain correct pump positioning
•  Replaces a hardened, cracked, split or leaking original grommet
•  Helps restore washer system reliability
•  Provides correct OE Porsche rubber fitment
•  Supports correct reassembly after washer pump or washer bottle service.

Why Replace This Part?
Washer pump grommets are exposed to washer fluid, age, temperature changes and repeated pump removal. Over time, the rubber can harden, shrink, crack or lose elasticity. A worn grommet may allow washer fluid to leak from the reservoir or cause the pump to sit loosely in the washer bottle. Replacing it with an OE Genuine Porsche washer pump grommet helps restore the correct seal and secure factory fitment.

Common Symptoms of a Faulty Washer Pump Grommet
•   Washer fluid leaking from the reservoir
•   Fluid dripping around the washer pump
•   Washer pump loose in the bottle
•   Cracked, hardened or perished rubber grommet
•   Washer fluid level dropping when the car is parked
•   Poor sealing after washer pump replacement
•   Dampness around the washer bottle area
•   Grommet damaged during pump removal.

When to Replace This Part
•   When replacing the washer pump
•   When removing the washer pump from the reservoir
•   If washer fluid is leaking around the pump seal
•   If the original grommet is cracked, hardened, split or missing
•   During washer bottle replacement
•   During windscreen or headlamp washer system repair
•   When restoring the washer system with correct OE Porsche parts
•   Whenever the grommet no longer seals the pump securely.

Where It Fits on the Car
This grommet fits in the washer fluid reservoir / washer bottle, where the washer pump pushes into the bottle opening. It acts as both a mounting bush and sealing gasket for the pump. Depending on model and equipment, it may be used for the windscreen washer pump and/or headlamp washer pump where specified.
