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.

The expansion tank is a vital part of the engine cooling system, storing coolant as it expands during normal engine operation and returning it to the cooling system as temperatures decrease. Replacing a worn or leaking reservoir helps maintain the correct coolant level, prevents overheating and protects the engine from costly damage.
What Does the Coolant Expansion Tank Do?
The coolant expansion tank performs several essential functions within the engine cooling system.
Its primary roles include:
- Providing a reservoir for expanding engine coolant.
- Maintaining the correct coolant level throughout the cooling system.
- Allowing coolant to return to the radiator and engine as temperatures fall.
- Helping maintain the correct system pressure when used with the pressure cap.
- Assisting with bleeding trapped air from the cooling system.
- Providing a convenient point for checking and topping up coolant.
A correctly functioning expansion tank is essential for maintaining stable engine operating temperatures.
Why Does the Expansion Tank Fail?
Expansion tanks are subjected to constant temperature fluctuations and system pressure, which can eventually weaken the plastic housing.
Common causes of failure include:
- Age-related plastic fatigue.
- Hairline cracks caused by repeated heating and cooling cycles.
- Coolant leaks around hose connections.
- Damage caused by excessive cooling system pressure.
- Discolouration and brittleness from prolonged engine bay heat.
- Internal contamination reducing coolant quality.
A leaking or cracked expansion tank can lead to coolant loss, low system pressure and engine overheating if left unrepaired.
When Should It Be Replaced?
Replacement is recommended when:
- Coolant leaks are visible around the tank.
- The reservoir has become cracked or distorted.
- The plastic has become brittle or heavily discoloured.
- Coolant level warnings occur without any obvious hose leaks.
- The cooling system is being overhauled.
- Replacing other ageing cooling system components during preventative maintenance.
Replacing the expansion tank before it fails can help prevent overheating and reduce the risk of expensive engine repairs.
