How to change the filter of the Mitsubishi ASX yourself

To perform the service on the Mitsubishi ASX in an orderly manner, work with the engine cold or warm, on a flat surface, with the car securely supported on jack stands and wearing appropriate personal protective equipment (PPE). Before starting, check the Mitsubishi ASX manual for the oil specifications and the types of filters compatible with your engine.

For the oil change on the Mitsubishi ASX, access the underside of the engine and place a large drain pan underneath.

Open the oil fill cap on top (this helps with draining), then unscrew the drain plug and allow the oil to completely drain out. Once the draining is finished, reattach the plug with the correct washer if required, and move on to the oil filter: unscrew the filter, clean the seating area, and install the new filter, lightly lubricating the gasket with a thin layer of clean oil. At this point, refill with the correct amount of oil for the Mitsubishi ASX, start the engine for a few seconds, turn it off, and check the level after a few minutes, ensuring there are no leaks.

For the air filter of the Mitsubishi ASX, locate the air filter box in the engine compartment, detach or unscrew the fasteners of the cover, remove the old filter, and clean the housing of leaves and dust without letting dirt enter the duct.

Insert the new filter in the correct orientation and close the box, ensuring that the seal is even. For the cabin filter of the Mitsubishi ASX, access the designated area for your version (usually on the passenger side) and open the flap or dedicated compartment.

Remove the filter, clean the area, and insert the new one, respecting the flow direction indicated on the filter, then close everything without forcing the clips. If your Mitsubishi ASX has a replaceable fuel filter (typical for diesel versions with an external filter), work carefully to avoid air entering the circuit and spills; prepare rags and a container, replace the filter according to the configuration, and if necessary, perform the priming procedure required for your version before starting the engine.
