Comfort in a car is made up of many little things, but none of them compares to the quality of the air you breathe during your trip. Owners of budget sedans such as ZAZ Chance, often encounter the problem of glass fogging and the appearance of unpleasant odors in the cabin, without even suspecting that the reason lies in a simply clogged filter element. The ventilation system in these cars is quite simple, but requires regular attention, especially considering the operating conditions on our roads.
Timely replacement of consumables allows not only to preserve the health of the driver and passengers, but also to extend the life of the heating and air conditioning system. A dirty filter creates resistance to air flow, forcing the heater motor to work with increased load, which can lead to its premature failure. In this article, we will analyze in detail the process of selecting and installing a new element so that you can complete the procedure yourself without extra costs.
Symptoms of contamination and the need for replacement
You can understand that the life of the filter element has come to an end by a number of indirect signs that should not be ignored. The first alarm bell is deterioration in airflow: even at maximum fan speeds, the air flow from the deflectors seems sluggish and insufficient to quickly warm up or cool the interior. This happens because the pores in the material are clogged with dust, fluff and small debris, physically blocking the path of air masses.
The second obvious sign is the appearance of a specific musty smell, especially noticeable when the stove is turned on in damp weather. The humid environment inside the filter housing in combination with organic matter (dust, plant spores) creates ideal conditions for the growth of bacteria and mold. Inhaling this air can cause allergic reactions, headaches and rapid fatigue of the driver, which directly affects traffic safety.
⚠️ Attention: If, when turning on the ventilation, you smell a strong burning smell or see smoke, immediately turn off the system and check the wiring or condition of the motor, as a clogged filter can cause overheating of system elements.
It is also worth paying attention to the frequency of fogging of windows. If the windows become covered with condensation almost instantly after getting into the car, even with the air conditioning running, it means that air circulation is impaired. The filter does not allow enough dry air to pass through, and moisture does not have time to be removed from the cabin. In winter, this creates a dangerous situation, reducing visibility to a critical minimum.
Selecting filter type: regular or carbon
The auto parts market offers owners ZAZ Chance There are two main types of filter elements, and choosing between them depends on your priorities and budget. The standard option is a simple fiber cloth that traps large dust, leaves and insects. It costs less and provides basic protection for the ventilation system, but is absolutely useless against gases and unpleasant odors.
The carbon filter has a more complex multilayer structure, where activated carbon granules are located between layers of synthetic fiber. Activated carbon has excellent adsorbing ability, retaining exhaust gases, fuel vapors and ozone. For residents of large cities or those who are often stuck in traffic jams, this option is the only right solution for maintaining health.
When purchasing a carbon filter, pay attention to the weight of the product - a high-quality element with carbon is always heavier than a regular analogue of the same size due to the density of the packing.
There is also a misconception that a carbon filter impairs airflow. Modern materials make it possible to maintain high throughput, so the difference in fan operation between the conventional and coal versions is ZAZ Chance almost imperceptible. The main thing is not to save on too cheap analogues from unknown manufacturers, which can spill out or become deformed after a month of use.
Necessary tools and preparation
Replacement procedure for ZAZ Chance belongs to the category of simplest operations that do not require special equipment or an inspection hole. You do not need to disassemble half of the dashboard or remove the pipes; access to the filter element is organized quite competently for a budget car. Everything you need can be found in any garage or even in the glove compartment.
To work you will need:
- 🛠️ Phillips screwdriver (for removing the cover fastening screws).
- 🔦 Flashlight (for illuminating the niche and checking the cleanliness of the channel).
- 🧹 Vacuum cleaner or compressed air (to clean the seat).
- 🧤 Gloves (so as not to get your hands dirty with dust and not touch the new filter).
Before starting work, the vehicle must be turned off and the heating system allowed to cool down if it was operating at full capacity. It is advisable to open the doors for ventilation, since when removing the old element, some of the accumulated dust may rise into the air. It is also recommended to prepare a damp cloth for final wiping of plastic surfaces.
☑️ Ready for replacement
Location and access to the filter element
By car ZAZ Chance The cabin filter is located in the engine compartment, under a plastic grille located at the base of the windshield on the passenger side. This arrangement is typical for many cars of this platform, but it has its own characteristics. The filter is located in a so-called “trough” or niche where rainwater flows, so it is important to keep the drainage holes clean.
To access it, you need to open the hood and find a black plastic panel (frill) that blocks access to the wiper mechanisms and air intake. It is under this panel that the filter housing is hidden. Unlike some models, where the filter is inserted from the side, here it is usually placed horizontally or at a slight angle in a special box.
⚠️ Attention: Be careful when working near the windshield wipers - do not damage the plastic fasteners or drop small parts or fasteners into the wiper drive mechanism, as this may cause jamming.
It is important to note that on some modifications ZAZ Chance Access may be slightly limited by cooling system pipes or vacuum hoses. In such cases, there is no need to use force - just carefully push away the interfering elements by hand or temporarily loosen the clamp, if the design allows it. The main thing is to ensure easy access to the filter cover.
What to do if access is blocked by pipes?
If the cooling system hose prevents you from removing the cap, do not try to bend or disconnect it without draining the antifreeze. Gently press down with your hand to create a gap, or twist the filter cover slightly to disengage it. If the vacuum booster hose is in the way, you can temporarily unclip it from its holder, but do not disconnect it from the manifold.
Step-by-step replacement instructions
The replacement process can be divided into several successive stages, compliance with which guarantees the correct result. First you need to remove the plastic cover (jabot), which is secured with several screws or clips. Unscrew all visible screws around the perimeter, carefully pull the plastic up and to the side, trying not to break the latches, which become fragile over time.
After removing the cover, you will see a metal or plastic frame covering the filter itself. It can be secured with latches or screws. Once you have access, remove the old filter element. This should be done slowly so as not to spill accumulated dirt inside the air duct. Pay attention to the airflow direction indicated on the frame of the old filter - this is a critical point for correct installation of the new one.
| Work stage | Action | Nuance |
|---|---|---|
| 1. Dismantling | Removing the frill and cover | Don't lose screws in the engine compartment |
| 2. Extraction | Removing the old filter | Remember the direction of the flow arrows |
| 3. Cleaning | Cleaning a niche with a vacuum cleaner | Remove leaves and debris from drainage |
| 4. Installation | Installation of a new element | The arrow should point in the direction of the air |
Before inserting the new filter, thoroughly vacuum the niche. Often leaves accumulate there, which when wet turn into mush and block the flow of water, which leads to moisture flowing into the interior. Wipe the seat with a damp cloth. Install a new filter, observing the direction of flow (usually the arrow points towards the cabin or down towards the fan). Close the lid tightly and replace the frill.
The most common mistake is installing the filter “in reverse”, when the air flow arrow is directed against the movement of air masses, which reduces the cleaning efficiency to zero and can damage the filter bellows.
Common mistakes and expert advice
Despite the simplicity of the operation, beginners often make mistakes that can ruin all the work. One of the most common problems is a loose fit of the filter cover or misalignment of the filter element itself. If there is a gap between the frame and the body, all the air will follow the path of least resistance, bypassing cleaning, and all the dust will immediately fall into the air conditioner evaporator and the interior.
Another mistake is ignoring the condition of drainage channels. The holes for water drainage under the frill, clogged with leaves, lead to the fact that when it rains, the water is level with the filter. As a result wet filter instantly loses its properties, begins to rot and lets water into the interior, which can lead to corrosion of the body or short circuit of the wiring.
- ✅ Always check the integrity of the rubber seal around the perimeter of the new filter.
- ✅ Do not try to wash or reuse disposable filters - the structure of the material is destroyed.
- ✅ Change the filter at least once a year, even if visually it seems clean.
⚠️ Attention: Never leave the filter niche open even for a short time without supervision - small rodents that like to build nests in warm air ducts, or large debris can get there.
It's also worth mentioning size compatibility. Sometimes filters from different manufacturers may have slight differences in geometry. If the new element has to be pushed in with force or is loose in the frame, it is the wrong size. Use only those models recommended for ZAZ Chance or its analogues (for example, Chevrolet Lanos), having previously checked the catalog numbers.
Frequently asked questions (FAQ)
How often do you need to change the cabin filter on a ZAZ Chance?
The recommended replacement frequency is once a year or every 10-15 thousand kilometers. However, if you often drive on dusty roads or live in a metropolis with poor ecology, it is better to reduce the interval to 6 months or 5-7 thousand km. Seasonal replacement (before winter and before summer) is considered the optimal strategy.
Is it possible to drive without a cabin filter?
Technically, the car will work without it, but this is highly not recommended. Without a filter, all dust, pollen, insects and small debris will settle directly on the heater radiator and air conditioner evaporator. Cleaning these units is much more difficult and more expensive than regularly purchasing inexpensive filter elements. Plus, you'll be breathing in whatever's on the road.
Why did a whistle appear after replacing the filter?
Whistling can occur for two reasons. The first is incorrect installation, when the filter is skewed and air passes through the cracks at high speed. The second is the use of a filter with too high a resistance (too dense), which the standard fan of the ZAZ Chance stove cannot cope with. Check the correct installation and tightness of the cover.
What is the difference between filters for ZAZ Chance and Chevrolet Lanos?
ZAZ Chance is a deep modernization of the Chevrolet Lanos, and in many components, including the ventilation system, they are identical. Filters for these models are usually interchangeable. However, before purchasing, it is better to visually compare the old and new element or check the catalog number, since in different years of production there may have been minor changes in the design of the air intake housing.
