Introduction

It appears that most people do not realize that the Jimny has a cabin / pollen filter, or at least has the facility for a cabin filter.

Most manuals never refer to it, even in the OEM Service Guide.

A lot of people, particularly those who drive off-road, are tired of the clouds of leaves that hit you in the face when you open the fascia vents. Fitting a cabin filter is straight forward once you know where it is (supposed to be) hidden.

If your Jimny already has a cabin filter installed (but you have not been aware of it), the filter is probably heavily clogged.


Used old cabin filter with charcoal particles
  • This is an example of a five year old (heavily used) cabin filter of unknown manufacturer, which was removed from a Jimny 3.
    • This is a filter which contains charcoal particles, so it is normal to look "dirty" / greyish, but not this much.
  • That picture was unfortunately taken just after the leaves and grit were brushed off off from the filter.
  • The weight of that used dirty filter was around 800 grams!



Required parts

The filter itself

Choose your air cabin filter wisely:

  1. There are many erroneous aftermarket compatibility claims (regarding dimensions) on the Internet.
    • First check if the dimensions match.
  2. Then choose a suitable filter type.
    • Your aim should be to match filter's filtering capabilities with your inhalation requirements.

Filter cover

Genuine cabin filter cover
  • You may wish to consider buying a spare cabin filter cover at the same time.
  • The part number of Suzuki's genuine cabin / pollen filter cover for Jimnys is: 95423-81A01
  • The suitable cover is also offered in BigJimny Shop.


Warning Icon.pngIt is common to break the filter cover when removing it as the plastic becomes brittle.




Changing / Installing a cabin filter

Tools

Spanner Icon.png
  • Assorted screwdrivers or blade


Warning Icon.pngI cannot emphasis too strongly how easy it is to break the old cover!




Installation

Passenger footwell
  • Here is the filter cover, up underneath the dashboard on the passenger side of the vehicle



Here is the cover in the footwell



Open brake caliper
  • First remove the glovebox.
  • This is done by flexing the sidewalls so the plastic retaining lugs can drop past the edge of the fascia.
  • Lower the whole glovebox away.
  • I am using a screwdriver with the end protected by a cloth to stop it marking the fascia, as I use it to prise away the retaining lugs.



Cabin filter cover retaining clips



Glovebox dropped open
  • The filter cover is retained by small clips on the end.
  • The tip of the scewdriver points to where the clip is (hidden).



Using blade to prise clip
  • Warm the plastic filter cover.
  • Either use a hairdrier or allow the car's own heater to warm the car (on re-circulate setting).
  • If the plastic is cold it is more likely to fracture.
  • Insert a small blade into the filter retaining lugs and gently prise it away from the edge of the moulded catches on the heater body.
  • Do this a bit at a time alternating front and back.



Inserting the cabin filter
  • If you have a UK Jimny, you are more than likely to find an empty hole now (full of bits of leafs).
  • Simply insert the cabin filter.



Press the new cover on
  • Gently press the filter cover back into place.



Broken!!
  • Don't think that you will be immune to breaking the filter cover - here is mine!
