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.
Fits:- Porsche 924 1977-85
- Porsche 924 S 1976-77
- Porsche 944 1983-87
Diagram Ref No 3
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.

Engineered to provide consistent fluid pressure and dependable operation, the washer pump works in conjunction with the washer reservoir, hoses and spray nozzles to ensure effective cleaning of the windscreen. Constructed from durable materials resistant to moisture, chemicals and temperature fluctuations, it is designed to provide long-lasting performance and reliable operation.
What This Product Does:
- Pumps washer fluid from the reservoir to the windscreen jets.
- Provides the pressure required for effective windscreen cleaning.
- Helps remove dirt, road grime, insects and debris from the glass.
- Supports safe driving visibility in all weather conditions.
- Works with the washer jet and hose system.
- Assists with maintaining a clear field of vision.
- Contributes to overall vehicle safety and convenience.
Symptoms Of Wear Or Failure:
- No washer fluid reaching the windscreen.
- Weak or inconsistent washer spray.
- Intermittent washer pump operation.
- Unusual buzzing, grinding or clicking noises from the pump.
- Washer fluid leaking around the pump housing.
- Washer motor running without fluid being sprayed.
- Complete loss of washer system function.
- Reduced visibility during wet or dirty driving conditions.
Why Replacement Matters:
- The windscreen washer pump operates in a harsh environment and is regularly exposed to moisture, washer fluid chemicals, temperature fluctuations and repeated electrical cycling. Over time, internal motor components, seals and impellers can wear or fail, reducing the pump's ability to deliver washer fluid effectively.
- A failing washer pump can compromise visibility by preventing the removal of dirt, salt, insects and road spray from the windscreen. Poor visibility significantly increases driving risk, particularly during adverse weather conditions. If left unresolved, washer system failure may also result in MOT or roadworthiness inspection issues where visibility equipment is required to function correctly.
- Replacing a worn or faulty washer pump restores reliable washer system performance, improves driver visibility and helps maintain vehicle safety. An OE Match replacement provides factory-style fitment, dependable operation and long-term durability, ensuring your Porsche's washer system continues to perform as intended.
