Many owners Nissan Almera Classic Over time, they encounter a characteristic problem: extraneous noise appears under the hood, and the smell of exhaust gases or moisture begins to penetrate into the interior. Often the root of evil lies not in the engine or ventilation system, but in the condition of the plastic part covering the area where the windshield wipers are attached. People call this part a “jabot,” although technically it is a decorative grille under the windshield. It is this that serves as a barrier between the engine compartment and the air intake area for the heating system.
During operation Nissan Almera Classic this plastic structure is exposed to aggressive influences: temperature changes, reagents, vibration from the motor and constant loads from the wipers. Over time, the plastic loses its elasticity, microcracks appear, and the rubber seals harden and come off. If you notice that a whistle is heard when the stove is operating, and in winter the windshield is covered with frost from the inside, most likely the problem is a leaky frill. Replacing the frill on a Nissan Almera Classic is not just an aesthetic improvement, but a critical measure to maintain the functionality of the stove and prevent corrosion.
Design features and functions of the grille
The part that we used to call a frill is actually a complex plastic panel consisting of several parts. In design Nissan Almera Classic it is attached directly to the body in the area of the windshield and performs several functions simultaneously. Firstly, it directs streams of rainwater into special drainage holes, preventing it from flowing into the interior or onto the stove fan. Secondly, it protects the engine compartment from large debris, leaves and dirt that can clog the radiators.
It is important to understand that the correct fit of this part ensures the correct operation of the ventilation system. If there are gaps between the body and the grille, air from the engine compartment will be sucked in, mixing with cold street air. This leads to the fact that the stove begins to “blow” cold even in the fan mode. In addition, vibrations from a running engine are transmitted to loosely fitting plastic, creating an irritating rattling sound that is clearly audible at idle.
Jabot design Nissan Almera Classic has its own fastening nuances. It is held in place by several plastic clips and bolts that can oxidize over time. Dismantling requires care, as old clips often break when trying to remove them. Tightness the connection is ensured by a special rubber band that runs along the perimeter of the attachment to the body. If this tape is torn or out of shape, the seal is compromised.

Diagnosis of faults and signs of wear
You can identify problems with frills before they lead to serious damage. The most obvious sign is the appearance of extraneous sounds when moving. If you hear a knocking or cracking sound in the windshield area that gets worse when you press the gas pedal, the plastic has most likely come away from the body. It is also worth paying attention to the operation of the wipers: if they begin to skip or jump, the grille itself may have become deformed, changing the geometry of the installation.
Another warning sign is moisture on the floor on the driver or passenger side. Moisture can enter the interior through leaks in the frill area, especially during heavy rains or when washing the car. Moisture accumulated under the panel often leads to corrosion of metal body elements and shorting of contacts in the windshield wiper control unit. Drainage holes can be clogged with leaves, which creates the effect of a bathtub under the grille, overflowing it and forcing water to find its way into the interior.
A visual inspection will also help identify problems. Open the hood and carefully inspect Nissan Almera Classic in the area where the frill is attached. Look for cracks, especially in areas where the plastic is under the most stress (usually corners and windshield wiper mounts). Pay attention to the condition of the rubber seals: if they are cracked, dried out or peeled off, they need to be replaced. Vibration from the motor can aggravate existing cracks, turning them into through holes.
Owners often complain that the interior smells of gasoline or exhaust fumes. This occurs due to a leak in the air intake system. Air from the engine compartment, saturated with fuel vapor or exhaust, is sucked into the stove and supplied to the cabin. This is not only unpleasant, but also dangerous to health. Leak testing should be carried out regularly, especially before the start of the heating season.
- Extraneous noise and rattling
- Water leaking into the cabin
- Exhaust smell
- Plastic cracks
Preparation for dismantling and necessary tools
Before you begin removing the frill, you need to prepare your work area and tools. Dismantling process Nissan Almera Classic does not require complex special tools, but does require accuracy and patience. You will need a set of screwdrivers (Phillips and flathead), a 10 mm socket, and a plastic spatula for prying out the clips. It is also advisable to have a container for storing small parts so as not to lose bolts and nuts.
First of all, you need to remove the wipers. To do this, you need to unscrew the nuts securing the levers and carefully remove them from the slots. Be careful not to scratch the windshield when removing the arms. After removing the wipers, access to the frill mounting bolts will open. In some cases, it may be necessary to remove plastic plugs that hide the mounting points. Use a plastic spatula to avoid damaging the body paint.
When dismantling, proceed slowly, being careful not to use excessive force. If the clip is stuck, try carefully prying it out with a flat-head screwdriver, after wrapping it with electrical tape to protect the plastic. You should also disconnect the connectors of the rain or light sensors if they are routed through the frill area. On Nissan Almera Classic There are usually no complex electronic components in this area, but check for wiring before removing.
☑️ Preparation for dismantling the frill
The process of replacing and installing a new part
Installing a new frill requires careful preparation of the seat. Clean the body surface from dirt, old mastic and rubber seal residues. This is critical to ensure a seal. Apply new sealant or install new rubber band around the perimeter of the fastener. Make sure the tape fits snugly and has no creases. On Nissan Almera Classic Special silicone seals are often used that can withstand temperature changes well.
Carefully install the new grille into place, lining up the holes for the bolts and clips. Do not tighten the bolts all the way right away. First, tighten all mounting points by hand to ensure that the part is level and free of distortion. After this, you can tighten the bolts to the required torque. Avoid over-tightening, as this can lead to deformation of the plastic and the appearance of new cracks. Check that the edges of the frill fit snugly to the body around the entire perimeter.
After installing the frill, return the wipers to their place. Make sure they are in the correct position and do not touch the edges of the grill. Start the engine and check the operation of the windshield wipers in different modes. Listen to the sounds: there should be no knocking or rattling. Also check for leaks by pouring some water onto the grille and making sure it goes into the drains and doesn't leak under the hood or into the interior.
- 🔧 Use a torque wrench to tighten the bolts.
- 🧼Clean the seat thoroughly before installation.
- 🌧️ Check the operation of the drainage holes after installation.
Elimination of vibrations and noise
Even after installing a new frill, vibration or rattling may persist. This is due to the fact that the plastic may touch metal body elements or other parts. To eliminate this problem, vibration-absorbing materials are often used. Apply a thin layer of vibration insulation to the inside of the frill where it touches the body. This will help dampen vibrations from the engine.
It is also worth checking the condition of the wiper mounts. If they are loose, they will transmit vibration to the frill. Make sure the nuts are tightened securely but not overtightened. Sometimes replacing the rubber gaskets under the wiper arms helps. On Nissan Almera Classic These gaskets lose elasticity over time, which leads to the appearance of gaps. Replace them with new ones to ensure a tight seal.
Another source of noise may be the stove fan itself. If its bearings are worn out, it will create vibration, which is transmitted to the frill. In this case, replacing the frill will not solve the problem, and the fan will need to be repaired or replaced. Test the fan at different speeds to eliminate this source of noise. Vibration isolation is an effective way to combat rattling, but it should not block the drainage holes.
How to apply vibration insulation correctly?
Before application, degrease the surface of the frill and body. Cut the material into small strips and glue them where the plastic meets the metal. Avoid applying material in areas with drainage channels. After application, press the material firmly and give it time to cure.-->
Selection of quality spare parts and analogues
When choosing a frill for Nissan Almera Classic It is important to consider the quality of the material. The original part is made of durable plastic that does not crack in the cold. Cheap analogues are often made from cheaper and brittle plastic, which can crack during the first winter. It is also worth paying attention to the accuracy of the geometry
a low-quality part may have distortions, which will lead to problems with tightness.
There are several manufacturers producing high-quality analogues of frills. Some of them offer parts with improved drainage systems or additional stiffeners. Before purchasing, compare the article numbers of the original part and analogues. Please note that all necessary fasteners and seals are included in the kit. Sometimes a set of new clips and bolts is sold along with the frill, which is very convenient.
You can also consider repairing the old frill if it is not seriously damaged. Cracks can be welded with plastic or sealed with epoxy resin. However, this is a temporary solution and does not guarantee longevity. If the part is severely deformed or has many cracks, it is better to replace it entirely. Investing in a quality part will pay off in the absence of noise and leakage problems in the future.

⚠️ Attention: Do not use aggressive chemicals to clean the frill, as they can destroy the plastic and seals. Use only special car shampoos or warm water and mild soap.
Prevention and care of the area under the windshield
To jabot on Nissan Almera Classic served for a long time and did not create problems, it is necessary to regularly care for the area under the windshield. Clean the drainage holes of leaves and dirt once a month. To do this, you can use thin wire or compressed air. Clogged drains are the main cause of leaks and water pooling under the grates.
It is also recommended to check the condition of the rubber seals. If they begin to tan, treat them with silicone grease. This will restore their elasticity and improve their tightness. Avoid using WD-40 for these purposes, as it can corrode the rubber over time. It is better to use special rubber conditioners, which are available at any auto store.
In winter, be especially careful when clearing snow and ice from your windshield. Do not use sharp ice picks or knives to avoid damaging the frill. Snow should be removed from the grill with a soft brush. Ice around the drainage holes must be removed carefully so as not to block the flow of water. Be aware that frozen water in drains can expand and crack the plastic. Regular inspection will help you avoid costly repairs in the future.
If you plan to park your car for a long time in winter, it is recommended to cover the area under the windshield with a protective film or cloth. This will prevent snow and ice from getting into the drainage holes. You can also install special plugs during parking, which will need to be removed before use. These simple measures will help extend the life of the frill and maintain its functionality.
⚠️ Attention: When washing a car with high pressure, do not direct the water stream directly at the joints of the frill with the body. Pressure can break the seals and force water inside the cabin.
Before the winter season, be sure to clean the drainage holes and treat the rubber seals with silicone lubricant to prevent freezing and cracking.
