Replacing the cabin filter Renault Logan 2

Replacing the cabin filter on Renault Logan 2 is required immediately if you smell a musty smell in the cabin or notice that the windows are fogging up even when the heating is on. Unlike the first generation of this model, where access was extremely difficult, in the second generation the engineers provided a more logical location of the air purification element, but the procedure still has its own technical nuances. Ignoring this procedure leads to the growth of bacteria in the air conditioner evaporator and reduced operating efficiency heater.

Timely installation of a new consumable ensures protection of the respiratory tract of the driver and passengers from road dust, pollen and exhaust gases. The replacement process does not require complex professional tools and takes from 15 to 30 minutes depending on experience. It is important to choose the right type of filter element, since the market offers many modifications that differ in size and material.

Location and selection of filter element

In the car Renault Logan 2 The cabin filter is located in a niche under the glove compartment (glove box) on the front passenger side. To access it, it is necessary to partially dismantle or lower the glove compartment lid, since the filter cassette is installed vertically and rests against the lower shelf. The air intake design here is designed to minimize moisture ingress while still providing sufficient air flow.

When choosing a new element, it is critical to consider its type: regular paper or carbon. Coal variants marked with markings Activated Carbon, are capable of trapping not only solid particles, but also harmful gases, however, they create slightly greater resistance to airflow. The overall dimensions of a standard filter for Logan 2 are usually about 235x190x30 mm, but before purchasing it is better to check the VIN code or measure an old sample.

The service life of a consumable directly depends on the operating conditions of the vehicle. In a metropolis with high dust levels and heavy traffic, the product's service life is reduced to 7-8 thousand kilometers. If you often drive on dirt roads, visual inspection and replacement should be carried out even more often to prevent the cells from becoming completely overgrown with dirt.

Necessary tools and preparation

The replacement procedure falls into the category of simple maintenance and does not require a lift or inspection pit. All work is carried out inside the car, so it is necessary to ensure good lighting of the work area, especially if the replacement takes place in the evening. The main tool will be a Phillips screwdriver, although in some configurations the fasteners may be slotted or absent altogether (clip system).

Before starting work, it is recommended to warm up the interior or, conversely, let the car cool down if the replacement is made immediately after the trip, in order to avoid burns from plastic elements. It is also worth preparing a vacuum cleaner or compressed air in advance to clean the niche from accumulated dirt, leaves and debris that could have gotten there during previous replacements.

• 🛠️ Phillips screwdriver (PH2) or screwdriver with an appropriate bit for removing self-tapping screws.
• 🔦 Powerful flashlight for illuminating the area under the glove compartment and inside the air duct.
• 🧹 A brush with soft bristles or a car vacuum cleaner for cleaning a niche.
• 🆕 New cabin filter of the appropriate size and type.

⚠️ Attention: Before starting work, turn off the engine and remove the key from the ignition so as not to accidentally start the heater fan, which can injure your hands.

Removing the glove box

Access to the filter element in Renault Logan II blocked by the bottom of the glove box. Depending on the year of manufacture and configuration, the travel limiting mechanism may differ: in some versions it is simply stops, in others it is a cable or an additional plastic bulkhead. In most cases, full access requires unscrewing the fixing screws.

Open the glove compartment and empty it of its contents. There may be mounting screws on the sides and bottom. Unscrew them carefully, being careful not to drop them into the cracks of the instrument panel. After removing the fasteners, the plastic box must be smoothly moved down and to the side, freeing access to the end of the filter housing.

Sometimes owners are faced with a situation where the plastic “hardens” in the cold. In this case, it is recommended to preheat the interior to avoid breaking the plastic latches or guides. Operate without sudden jerks, controlling the breaking force.

Removing the old filter and cleaning the niche

Once access is opened, you will see the end cover of the filter housing, which is usually secured with latches or simply inserted tightly into the grooves. Lightly press the latches and remove the cover. The old filter may fit tightly, so you need to pull it evenly, grabbing it by the edge of the frame.

When removing, pay attention to the air flow direction indicated on the frame of the old element. This will help you install the new part correctly. Often a significant amount of leaves, insects and dust accumulate inside the niche, which can clog the drainage holes or get into the air conditioner evaporator.

Use a vacuum cleaner with a narrow attachment or compressed air to thoroughly clean the cavity. If mold or a persistent unpleasant odor is found there, it is recommended to treat the surfaces of the niche with an antibacterial spray for car air conditioners and let it dry before installing a new element.

Installation of a new filter and assembly

Installation of a new consumable is carried out in the reverse order of dismantling. The key point is to follow the direction of air movement, which is indicated by an arrow on the side of the filter. On Logan 2, the air moves from bottom to top or from front to back, depending on the specific modification of the air duct, but most often the arrow should point down (towards the floor) or towards the cabin when looking at the end.

Carefully insert the filter into the guide grooves. It should go in without undue force. If the element is deformed or has incorrect dimensions, do not try to push it in by force, as this will lead to a violation of the seal and leakage of untreated air bypassing the filter paper.

After installing the filter, return the end cover of the housing until it clicks into place. Then put the glove compartment in place, tighten all the fastening screws and check the smooth movement of the door. Make sure there is nothing blocking the drawer from closing and that all gaps are straight.

Comparison of filter types: paper or carbon?

The choice between a regular paper and carbon filter often raises questions among owners Renault Logan. Paper options are cheaper and provide basic protection against coarse dust and lint. Carbon filters have a multilayer structure with the addition of activated carbon, which allows them to adsorb unpleasant odors and harmful gases such as nitrogen and sulfur oxides.

The difference in price between them can reach 50-100%, but for residents of large cities, the coal option is a more justified investment in health. However, it is worth remembering that the resource of the carbon layer is limited and may end before mechanical filtration is exhausted, so they need to be changed regularly.

The table below provides a comparison of the main characteristics for ease of selection:

Typical errors and troubleshooting

When replacing things on their own, owners often make a number of mistakes that negate the whole point of the procedure. The most common of them is to install the filter upside down or sideways, ignoring the flow direction markings. This leads to the fact that the filter material quickly becomes clogged on the back side and breaks under air pressure.

Another mistake is using smaller filters with foam rubber or rags for sealing. Such “collective farm” methods disrupt the aerodynamics of the system and can cause whistling or humming during ventilation operation. Always use items that exactly match specifications Renault Logan 2.

If a whistle appears after replacement, check the tightness of the housing cover. Insufficiently latched latches create gaps through which air passes with a characteristic sound. Also, a whistle can occur if there is debris left in the niche that gets on the fan blades.

⚠️ Attention: Never leave a niche open, even for a short time, without a filter or plug installed, if the fan is running. Large debris can instantly damage the impeller or jam the motor.
