The situation when, the next time you turn on the wipers or try to wash the windshield, you hear a suspicious knock or see a plastic reservoir dangling under the hood, is familiar to many motorists. Most often, the problem lies in a trivial detail - it’s out of order. washer reservoir clips, which ensure the fixation of the container in the engine compartment. Ignoring this malfunction can lead to much more serious consequences than just noise, so it is important to understand how to properly select and install new fasteners.
In modern cars plastic fastener widely used due to its lightness, corrosion resistance and low production cost. However, it is plastic that suffers from temperature changes, engine vibrations and aggressive chemicals that we pour into the glass cleaning system. If you notice that the tank has moved from its normal place, you must immediately check the condition of the latches, since friction of hoses against the body can lead to rapid wear of rubber and fluid leakage.
In this article we will look in detail at what types of fasteners exist, how to properly dismantle them without damaging the tank itself, and what to look for when purchasing new parts. You will learn about the installation nuances depending on the car brand and understand why using universal analogues is not always the best solution for long-term operation.
Types of fastenings and design features of tanks
Before you go to an auto parts store, you need to clearly understand what type of fixation is used in your car. The design of washer reservoirs can vary significantly: from simple bolted containers to complex systems with integrated pumps and fluid level sensors. In most cases it is used plastic clips, which operate on the snap-in principle.
There are several main types of such fastenings. The most common are the so-called “pistons” with expanding antennae, which are inserted into a hole in the body and fixed by pressing on the central cap. Another option is clamp clamps that surround the tank body and are screwed to body elements or side members. For cars with a transverse engine, combined systems are often used, where the tank is held in the fender niche by special rubber dampers and metal brackets.
It is also important to consider the material of the tank itself. This is usually high-density polyethylene, which has a certain elasticity, but becomes brittle at low temperatures. If you try to install a hard metal clip on frozen plastic, there is a high risk of cracking. Therefore, manufacturers often use composite materials or special types of plastic for the clamps themselves so that their coefficient of thermal expansion matches the material of the tank.
Symptoms of wear and troubleshooting
You can determine that the washer reservoir clips require replacement long before the reservoir finally falls off or leaks. The first and most obvious sign is an extraneous sound. When driving on uneven roads or while the engine is idling, you may hear a distinctive clunking or thumping noise from the front of the vehicle. This happens because loose fasteners allows the container to perform oscillatory movements.
The second sign is visual distortion. If you open the hood and inspect the engine compartment, you will notice that the neck of the tank has shifted relative to the hole in the mudguard, or the tank itself is skewed to one side. In some cases, fluid supply hoses become stretched, which creates excess pressure on the connections and can lead to pipes breaking off the pump or injectors.
⚠️ Attention: If you notice a constant decrease in the fluid level without visible signs of leakage on the asphalt, check the integrity of the hoses where they pass through the body. A loose tank can rub the tube against the sharp edge of the metal frame of the body.
It is also worth paying attention to the operation of the washer system. If, when the pump is turned on, the pressure in the nozzles becomes weaker, or the pump operates intermittently, it is possible that due to the displacement of the tank, the angle of liquid intake has changed, and the pump began to capture air. This is especially true for vehicles that are often driven on rough terrain or steep inclines.
Tools and preparation for replacing fasteners
To carry out the procedure for replacing clips, you do not need a complex professional tool, but having the right equipment will greatly simplify the task and protect the car body from scratches. First of all, it is necessary to ensure good access to the tank. In some car models, this simply requires opening the hood, in others it may require partial dismantling of elements engine compartment, for example, removing a decorative plastic trim or air filter.
The basic set of tools includes a flat-head and Phillips screwdriver, a set of sockets with a wrench, and special pullers for plastic clips. The use of metal screwdrivers to pry up plastic is not recommended, as there is a high risk of damaging the paintwork or breaking adjacent fasteners. If you don’t have a puller, you can use a thin awl or a medical clamp, but you need to act extremely carefully.
☑️ Preparing to replace clips
Before starting work, be sure to let the engine cool down if the vehicle has just been driven. The plastic of the tank and adjacent elements may be hot, which increases the risk of damage due to mechanical impact. It is also recommended to disconnect the negative terminal of the battery to prevent accidental activation of the washer pump or short circuit when working near electrical connectors.
Step-by-step instructions for removal and installation
The replacement process begins with freeing access to fasteners. If the tank is full, the liquid must first be pumped out with a syringe or the pump must be removed and drained through the hole. After this, carefully disconnect the electrical connector of the washer pump. It is usually secured with a plastic latch that must be pressed with your finger or a thin screwdriver.
Next comes the dismantling of the old clips. If these are pistons with a central cap, their center must be pressed inward (or pulled outward, depending on the design), after which the entire clip can be easily removed by hand. If the fastener is a clamp, you will need to loosen the bolt or screw. When removing, try not to apply excessive force to the tank itself, so as not to deform its seats.
Sequence of actions:1. Release the pump connector lock.
2. Remove the hoses from the nozzles (tighten the ends so that residual liquid does not leak out).
3. Unscrew the bolts securing the clamps or pull out the pistons.
4. Remove the tank from the niche.
5. Clean the seats from dirt and rust.
Installing new clips is done in the reverse order. It is important to correctly align the holes in the tank and body. When the pins are snapped into place, a clear click should be heard, indicating reliable fixation. If a bolted connection is used, do not overtighten the bolts to avoid pushing through the plastic.
⚠️ Attention: Never use force if the clip does not fit into place. Check to see if the edge of the hole is touching a rib or wiring. Forced installation can lead to destruction of the mounting lugs on the tank itself.
Comparison table of fastener materials
When choosing new clips, the question often arises: to buy original spare parts or universal analogues. The difference lies not only in price, but also in the properties of the materials. Below is a comparison of the main characteristics of different types of mounts.
| Material type | Temperature resistance | Elasticity | Service life |
|---|---|---|---|
| Original plastic (PA66) | High (-40...+120°C) | Moderate | 5-7 years |
| Universal polyethylene | Medium (-20...+80°C) | High | 2-3 years |
| Metal clamps | Very high | Missing | 10+ years |
| Rubber dampers | Medium (crack in the cold) | Very high | 3-4 years |
As can be seen from the table, metal clamps seem to be the most reliable option, but they have one significant drawback - the lack of shock absorption. Engine vibrations will be directly transmitted to the tank, which can lead to its destruction in places where the seams are soldered. Original plastic often contains special additives that prevent aging of the material under the influence of ultraviolet radiation and road reagents, which cheap analogues lack.
The Secret to Durable Rubber Mounts
If you use rubber dampers, lubricate them periodically (once a year) with silicone grease. This will prevent the rubber from drying out and the appearance of microcracks, which in the cold will lead to rupture.
Nuances of operation in winter
Winter is the most severe test for any plastic elements of a car. At this time of year, the risk of washer reservoir clips breaking increases many times over. The frozen liquid inside the tank expands, creating enormous pressure on the walls and attachment points. If the clips are old and have lost their elasticity, they may simply burst under load.
In addition, winter “chemicals” on the roads have an aggressive effect on all components of the car. The saline solution, when it gets on the plastic, accelerates the process of its degradation. Therefore, before the onset of cold weather, it is recommended to inspect all fasteners under the hood. If you see that the plastic has become lighter in color (the “graying” effect) or is covered with a network of small cracks, it is better to replace such a part preventively.
Owners of cars with plastic tanks located in the area of direct contact with the wheels (for example, in arches) should consider installing additional protection or using more durable materials for fixation. Sometimes simply wrapping the tank with vibration-isolating material helps reduce vibration and protect the plastic from impacts from small stones.
Use anti-freeze products only from proven brands. Cheap liquids often contain alcohols, which have an aggressive effect on some types of plastic, making them brittle after just one winter.
Common mistakes when doing DIY repairs
Replacing clips yourself is not a difficult task, but even here you can make mistakes that will ruin all your efforts. One of the most common problems is using the wrong size fasteners. Many car owners buy universal “100 in 1” kits, hoping to find a suitable option. However, a difference in the diameter of the cap or the length of the stem of 1-2 millimeters can lead to the fact that the clip either does not snap into place or will dangle.
Another mistake is ignoring the condition of the mounting holes. If dirt, rust, or remnants of the old clip have accumulated in the hole in the body, the new clip will not fit tightly. This will lead to the tank starting to “walk” under load, and the new clip will break very quickly. Before installation, be sure to clean the holes with a brush and blow with compressed air.
⚠️ Attention: Do not try to secure the tank with wire or pipe clamps as a temporary solution. The vibration will quickly grind the metal against the plastic, and you will get a hole in the tank or body, the repair of which will cost much more than a set of original clips.
Also, do not neglect the quality of the clips themselves. Cheap Chinese plastic is often overheated and breaks in your hands when trying to install. It is better to spend a little more time searching for the original catalog number or a high-quality analogue from well-known manufacturers of auto fasteners, such as Fastener or AutoKlip.
The quality of fasteners directly affects the safety of the tank and the absence of extraneous noise. Saving on clips can lead to replacing the entire assembly.
Conclusion and final recommendations
The washer reservoir clips are a small but critical detail for driving comfort and safety. A properly functioning windshield washer system is essential in any weather, and reliable operation starts with a strong foundation. Regular inspection of the engine compartment and timely replacement of worn-out elements will help you avoid unpleasant surprises on the road.
Remember that the correct selection of material and strict adherence to installation technology guarantee a long service life of the unit. Don’t be afraid to turn to specialists if you doubt your abilities, but self-repair with minimal skills is quite possible and economically justified.
Lifehack for searching for an article
To find the exact part number of the clip for your car, you don’t have to look into catalogs. Take a photo of the entire clip on the other side of the body (for example, from the door trim) and show the photo in an auto parts store - sellers can often find an analogue visually.
FAQ: Frequently asked questions
Can I use metal clips instead of plastic ones?
Theoretically, it is possible if they fit perfectly and do not require drilling new holes. However, metal does not dampen vibration, which can lead to rapid wear of the tank walls at the points of contact. In addition, the metal is susceptible to corrosion. It is better to use reinforced plastic.
Why do clips break in winter?
In the cold, plastic loses plasticizers and becomes brittle. Any vibration or attempt to compress and expand the tank when the temperature of the liquid changes leads to destruction of the structure of the material.
Where can I find the original clip number?
The original number (OEM) can be found in electronic spare parts catalogs using the VIN code of your vehicle. Also, the number is often stamped on the back of the clip itself, if it is intact.
How to temporarily secure the tank if the clip breaks on the road?
In an emergency, you can use a plastic tie clamp (tie) of a suitable length, passing it through the hole in the tank and behind the standard hole in the body. Place a piece of rubber or thick fabric to prevent the clamp from rubbing the plastic.
