How To Change a Cabin Filter on a Toyota Sienna

Cabin air filters are accessories made up of fibrous materials that eliminate solid particles like dirt, pollen, sand, dust, mold, germs, bacteria and other microorganisms from the air. Filters are most commonly used to ensure that the air is sufficiently clean for ventilation systems and for engines. A car's cabin filter is meant to filter out dust, dirt and other particulates from the air inside the passenger cabin. This is an accessory that should be regularly changed, to ensure that the air conditioner does not get clogged with dust, and that passengers enjoy clean air.

Having congested or filthy cabin air filters will result in a decrease the airflow from the cabin vents. It can also bring in particles that can cause allergens to enter into the cabin's air stream. Nearly all newly-bought vehicles are prepared with an efficient cabin air filter to aid in blocking the pollutants, but some budget automobiles, like subcompacts, don't come with a cabin filter pre-installed.

  • Read the maintenance schedule in the vehicle's manual. Toyota recommends changing the Sienna's cabin filter every 12,000 miles, after which the accessory's service life is finished and should be replaced. This should be a standard procedure wen your car undergoes periodic maintenance service, but you can do-it-yourself if you are familiar with the instructions, to avoid having to pay labor charges. It's a simple procedure that can be done in five to 20 minutes.
  • Find the location of the cabin air filter housing. The cabin air filter is usually hidden behind the glove compartment. Open the glove box and clear all the contents. Look for the screw at the lower right area of the box and unscrew using the screwdriver. This screw connects the glove box rod to a support arm. Taking this out will help slip the rod off of the arm. After this, pull both side of the glove box together an in inward direction and pull it out completely. This allows you to have full access to the cabin air filter housing. Remove the filter housing by pulling the tabs from both sides.
  • Slip out the used filter and replace with a new one. Gently pull the filter and take it out. The filter should slip off easily. You can also insert a new filter easily, as well.  Make sure to insert the new filter with the proper suitable air flow direction. Then, reinsert the housing and lock it. The locks are positioned beneath the tabs on the right and left sides of the housing.
  • Pivot the glove box back into place and slip on the rod back onto the arm. Reinsert the screw into the lower right area of the glove box and tighten. Make sure that the screw is secured, but not too tightly. Return the contents of your glove box.

With this easy process, you do not need to visit a professional mechanic to change your cabin filter. Buying a filter online or from auto supplies shops should cost only about $10 to $20. However if you find any problems in or after replacing the filter, it is best to consult a qualified mechanic.
