Windshield washer fluid reservoirs are typically made of plastic due to its ability to be formed into complex shapes. Plastic is also used because it is durable and long-lasting. The reservoir is an essential component of the washer system, storing and pumping the fluid through plastic lines to the washer nozzles, which spray the fluid onto the windshield. The reservoir's location varies depending on the vehicle, but it is usually found near the radiator or engine bay. It is typically translucent, with marks indicating the fluid level, and has a removable cap for refilling. While plastic reservoirs are long-lasting, they can crack and leak due to extreme temperatures or the use of water instead of washer fluid.

What You'll Learn
Plastic is durable
Plastic is a versatile material that can be moulded into various shapes. This quality makes it ideal for use in reservoirs, which come in different shapes and sizes to fit the available space in a car's engine bay. Plastic's ability to be formed into complex shapes allows for the creation of reservoirs that can maximise fluid capacity while adhering to spatial constraints.
The durability of plastic reservoirs is evident in their longevity. Unlike other car components, windshield washer reservoirs are not known to wear out over time. They are designed to be long-lasting, and their durability contributes to their permanence.
However, plastic reservoirs are not immune to damage. They can crack and leak, especially when exposed to extreme temperatures or filled with water instead of washer fluid. In cold climates, water in the reservoir can freeze, causing the plastic to harden and crack when it thaws. This results in fluid leaks.
Despite these vulnerabilities, plastic reservoirs remain a durable and reliable component of automotive systems. Their construction from high-grade plastic ensures they can withstand the demands of their function and provide consistent performance over an extended period.

Plastic is cost-effective to replace
Plastic reservoirs are also easy to replace due to their location under the hood, usually near the radiator or engine bay. In most vehicles, installation is simple: disconnect the hose, unbolt any mounting hardware, and swap in the new reservoir. This accessibility and ease of replacement contribute to the cost-effectiveness of plastic reservoirs.
The use of plastic in these reservoirs also relates to their cost-effectiveness. Plastic is a lightweight and versatile material that can be formed into complex shapes. This allows for efficient use of space in the engine compartment and accommodates various vehicle designs. Plastic's lightweight nature also contributes to overall vehicle efficiency and performance, which can impact long-term costs for car owners.
Additionally, plastic reservoirs often have marks or level sensors that indicate the fluid level. This helps drivers monitor and maintain the appropriate fluid level, preventing potential damage caused by overfilling or running empty. Maintaining the correct fluid level also contributes to cost-effectiveness by reducing the need for repairs or replacements due to fluid-related issues.
While plastic reservoirs may need replacement due to cracks or leaks, they are generally durable and long-lasting. Some sources mention that the plastic used is high-grade and can last indefinitely. Therefore, plastic reservoirs offer a balance between durability and cost-effectiveness, making them a practical choice for vehicle manufacturers and owners alike.

Plastic is mouldable
Plastic is an incredibly versatile material, and its mouldability is one of the key reasons why it is used for windshield wiper fluid reservoirs. Plastic can be formed into complex shapes, which is essential for the many different vehicle designs and engine layouts. The mouldability of plastic allows for the creation of reservoirs that can fit into tight spaces, maximising efficiency and ensuring a proper fit.
The moulding process also enables the addition of specific features to the reservoir design. For example, marks or level sensors can be incorporated to indicate fluid levels. This helps drivers easily monitor the amount of washer fluid in their vehicles and refill it when necessary.
Another advantage of plastic mouldability is the ability to create translucent reservoirs. Translucent plastic allows drivers to visually inspect the fluid level without the need for additional sensors or indicators. This feature simplifies the design while still providing essential information to the driver.
Furthermore, plastic moulding techniques can be used to create reservoirs with varying capacities to accommodate different vehicle sizes and requirements. The mouldability of plastic ensures that reservoirs can be tailored to fit specific vehicles, from compact cars to large trucks and SUVs.
The mouldability of plastic has revolutionized the design and functionality of windshield wiper fluid reservoirs. By utilising plastic's ability to be formed into complex shapes, manufacturers can create reservoirs that not only fit seamlessly into vehicles but also incorporate features that enhance the overall driving experience and maintenance of the system.

Plastic is see-through
One of the reasons why windshield wiper fluid reservoirs are made of plastic is that plastic is see-through. The translucency of plastic allows drivers to see how much fluid is in the tank without having to open the reservoir. This is important because it helps drivers ensure that their fluid levels are sufficient before getting on the road.
The use of plastic in the construction of windshield wiper fluid reservoirs also allows for the inclusion of marks or fill lines on the sides of the reservoir, indicating the maximum fluid capacity. This feature, combined with the see-through nature of plastic, enables drivers to easily monitor their fluid levels and refill the reservoir when necessary.
In some vehicles, the windshield washer fluid reservoir may be equipped with a level sensor mounted inside, providing an additional way to monitor fluid levels. However, the translucent property of plastic remains a key advantage, offering a visual indication of the fluid level at a glance.
It is worth noting that while plastic is the standard material for modern windshield wiper fluid reservoirs, classic cars from the past sometimes used glass reservoirs. The transition to plastic reservoirs offers several advantages, including weight reduction and the ability to form complex shapes during manufacturing.
The see-through nature of plastic in windshield wiper fluid reservoirs is a significant factor in maintaining proper fluid levels and contributing to overall vehicle maintenance. By allowing drivers to visually inspect their fluid levels, plastic reservoirs help ensure that the windshield washer system remains functional and effective.

Plastic is replaceable
Windshield washer fluid reservoirs are typically made of plastic, and they are designed to be replaceable. Plastic is a versatile material that can be moulded into complex shapes, making it ideal for the various reservoir designs needed to fit the engine compartments of different vehicles.
Plastic is susceptible to damage, especially when exposed to extreme temperatures. For example, in cold weather, water inside the reservoir can freeze, causing the plastic to crack as it expands. Similarly, rapid temperature changes can cause the plastic to split at the seams. In older vehicles, the heat from the exhaust system can also cause the plastic to crack over time.
Leaking reservoirs are a common issue, and the only solution is to replace the entire unit. Fortunately, plastic reservoirs are relatively inexpensive and easy to replace. The process typically involves disconnecting the reservoir from the washer nozzles and pump, unbolting any mounting hardware, and swapping in a new unit. The cost of parts for a replacement reservoir ranges from $100 to $120, and the labour cost for a professional mechanic is usually between $30 and $200.
While plastic reservoirs may not last forever, their replaceability ensures that drivers can maintain clear visibility while driving.
