What This Product Does:
- Delivers washer fluid from the front washer pump to the front windscreen jets
- Ensures consistent fluid flow and pressure for effective cleaning
- Serves as part of the washer system plumbing alongside the pump, reservoir, and spray nozzles
- Prevents fluid leaks and ensures jets operate as designed
- OEM design means correct length, diameter, and connection points for a direct fit
- No washer spray from the front windscreen jets
- Weak, intermittent, or uneven spraying
- Visible washer fluid leaks under the front of the vehicle or in the engine bay
- Washer fluid reservoir depletes quickly with little or no fluid reaching the jets
- Hose looks cracked, brittle, bent, or collapsed on inspection
- Washer pump sounds normal yet no fluid sprays
Why Replacement Matters:
- A functioning washer system is vital for removing rain, dirt, road film, bug splatter, and other debris — crucial for maintaining unobstructed windscreen visibility and safe driving in changing road conditions.
- If the hose is leaking or blocked, the washer pump may run dry or under stress, which can lead to premature wear or failure of the washer motor — a more expensive part to replace.
- Using the genuine part ensures the correct fit, sealing surfaces, connection diameter, and routing clips, avoiding leaks and improper alignment that can occur with generic hoses.
- Factory-specified materials resist temperature extremes and chemical exposure, meaning this hose stays flexible and leak-free longer than inferior replacements.
- Even minor plumbing components contribute to a well-maintained vehicle. A fully functioning washer system reflects good maintenance and supports overall vehicle condition and resale value.

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.
