Fresh air inside a car is not just a matter of comfort, but also a critical aspect of the health of the driver and passengers. Over time, the ventilation system becomes clogged with dust, lint and small particles, which reduces the efficiency of the stove and air conditioner. On Nissan Murano this problem is solved quite simply, but requires precise knowledge of the location of the element.
Many crossover owners are looking for an answer to the question of where exactly this consumable is hidden. Depending on the year of manufacture and generation of the model, the design may differ slightly, but the principle of access remains similar. Ignoring replacement leads to glass fogging and unpleasant odors.
In this article, we will look in detail at how to find a filter, what tools you will need, and how to do the work yourself without contacting the service. You will receive clear instructions that will save you time and money on the services of specialists.
Filter location depending on Murano generation
The first thing you need to do is determine the generation of your car, since the architecture of the engine compartment is changing. On Nissan Murano the second generation (Z51) and third (Z52) filter is usually located in a niche behind the plastic trim on the passenger side.
You will have to open the hood and find the rubber seal near the windshield. It is under it, hidden by a decorative plastic cover, that there is an air intake chamber. On some trims, access may be limited if you have additional accessories or protection installed.
The key is to correctly identify the access side. Do not try to look for the element on the driver's side or in the depths of the engine compartment near the engine - this is a waste of time. The design provides access exclusively from the front passenger side.
⚠️ Attention: Do not try to remove the cover with excessive force, as the plastic clips are Nissan Murano Quite fragile and can break if handled carelessly.
Tools and preparation for the replacement procedure
You don't need a complicated mechanic's kit to get the job done. It is enough to have basic tools on hand, which can be found in every garage. The main tool will be a flat-blade screwdriver, since the cover is often secured with plastic clips.
It is also recommended to prepare gloves to avoid getting your hands dirty from the dirt that has accumulated under the pad. If you plan to change the filter yourself, make sure the car is parked on a level surface and the engine is completely cool.
In some cases, a flashlight may be needed if the lighting in the engine compartment is not bright enough. This will allow you to examine the fasteners and not lose small parts during dismantling.
☑️ Preparation for replacement
Step-by-step instructions for removing the cover
The process of removing the cover begins with a visual inspection of the area above the gas pedal on the passenger side. You will see a black plastic grill covering the entrance to the ventilation system. It is secured with several clips that need to be carefully snapped off.
Insert a flathead screwdriver into the slot of the latch and apply light pressure to release the latch. Repeat this operation with all fasteners, not forgetting that plastic can be cold and brittle in the winter season.
After unfastening all the clips, the cover is removed by hand. Be careful as it may be stuck to the seal due to dirt or moisture. If resistance occurs, check to see if you forgot to unfasten the last fastener.
Once the cover is removed, you will see the filter itself. It is located in a special tray and can be clogged with leaves or debris that has fallen from above. Remove large debris by hand before removing the element.
What to do if the clips are stuck?
If the latch does not budge, try slightly rocking the lid up and down while pressing down on the latch. Do not use metal tools to pry up the plastic to avoid leaving scratches.
Installing a new filter and checking operation
Before installing a new element, be sure to compare it with the old one. There is an arrow on the filter housing indicating the direction of air flow. An installation error may result in the filter not working effectively or even tearing it out of its socket.
Insert new cabin filter into the tray until it stops. It should fit tightly, not dangle and have no gaps around the perimeter. If the filter is too loose, check to see if the tray is bent or the element itself is deformed.
After installing the filter, return the plastic cover to its place. Make sure that all latches click into place with a characteristic sound. This guarantees the tightness of the system and the absence of extraneous sounds during ventilation operation.
Start the engine and turn on the ventilation at maximum speed. Check to see if the system whistles or smells coming from the vents. If everything works properly, the replacement was successful.
Before purchasing a new filter, look inside the old one and look at the side of it. Sometimes manufacturers change the design of the case, and the new element may not fit, even if it is stated as compatible.
Comparison of filter types and selection criteria
There are two main types of filters on the market: carbon and regular paper. Conventional filters trap dust and large debris well, but do not cope with unpleasant odors and exhaust gases. Carbon models contain activated carbon, which absorbs odors and harmful substances.
The choice depends on your preferences and operating conditions. If you often drive in traffic jams in a city where there are a lot of exhaust fumes, the coal option will be optimal. For country trips, a regular filter is also suitable.
It is important to pay attention to the manufacturer. Original parts from Nissan They are usually of high quality, but there are also high-quality analogues from brands such as Mann, Mahle or Bosch. Avoid cheap knock-offs as they can quickly clog and put a strain on the fan.
| Filter type | Benefits | Disadvantages |
|---|---|---|
| Regular (paper) | Low cost, good dust filtration | Does not remove odors, clogs faster |
| Coal | Eliminates odors, traps gases | High price, slightly less air flow |
| Original Nissan | Perfect fit, guaranteed quality | High price, often sold as a set |
| Analogues (Mann, Mahle) | Excellent value for money | There may be differences in size between cheaper versions |
A carbon filter is the best choice for urban use, as it effectively neutralizes exhaust odors, unlike its conventional paper counterpart.
Replacement frequency and signs of contamination
Manufacturers recommend changing the cabin filter every 15,000 kilometers or once a year, whichever comes first. However, in dusty regions or during active use in traffic jams, this interval should be reduced to 10,000 kilometers.
There are clear signs that the filter needs replacing. If you feel an unpleasant odor when you turn on the ventilation, hear a whistle, or see that the windows are fogging up faster than usual, this is a reason to check the element.
Sometimes the filter can be so clogged that the air flow from the baffles becomes very weak even at maximum fan speed. In this case, replacement is required so as not to overload the stove motor.
Regular replacement not only improves air quality, but also extends the life of your air conditioning system. A clean filter ensures optimal airflow, reducing fan and evaporator wear.
- Once a year
- Once every 10,000 km
- Only when it starts to smell
- Never changed
Service features for different years of manufacture
On Nissan Murano In the first years of production (before 2014), access to the filter may be a little more difficult due to the way the plastic cover is attached. Sometimes it is necessary to remove part of the seal or unscrew an additional screw.
In newer models (after 2015), manufacturers often simplify the design, making the retainers more affordable. However, it is worth remembering that the design of the engine compartment may vary depending on the configuration and market.
If you have a modified vehicle with additional equipment installed, access may be blocked. In such cases, it is recommended to consult a specialist or study the manual specifically for your modification.
Proceed slowly and carefully to avoid damaging any body or interior components.
Possible problems with self-replacement
One of the common problems is the loss of cover latches. If you accidentally break or drop a clip, you will have to buy a new set or look for a replacement in specialized stores. This may delay the replacement process.
Sometimes the filter may not be installed correctly from the factory. If you see that the old element is crooked or sticking out, do not repeat this mistake. Align it correctly before installing the new one.
Another problem is dirt that can get into the vent when removing the cover. It is recommended to vacuum the area around the hole beforehand or use a damp cloth to wipe.
⚠️ Attention: If you are not confident in your abilities or are afraid of damaging the plastic, it is better to entrust this work to professionals, since replacing the cover may take longer than replacing the filter itself.
In some cases, water may accumulate at the bottom of the tray due to a clogged drain. Be sure to check this before installing a new filter, otherwise it will quickly become damp and lose its properties.
⚠️ Attention: The presence of water in the tray is a sign of a clogged drainage hole. Clean it before installing the filter, otherwise condensation will accumulate inside the system.
What to do if the filter does not fit?
If the new filter does not fit into the tray, check to see if it is bent. Sometimes items become deformed during transportation. Gently straighten them with your hands without using excessive force.
