18. Changing filters: When and how to do it

The proper maintenance of a vehicle is essential to ensure its optimal performance and extend its useful life. One of the most important aspects of maintaining a vehicle is changing filters regularly. There are several filters on a vehicle, each performing a specific function to keep your car running smoothly. In this chapter, we'll discuss when and how to change your vehicle's filters.

What are the different types of filters on a vehicle?

There are four main types of filters on a vehicle: the engine air filter, the oil filter, the fuel filter, and the cabin air filter. Each of these filters plays a vital role in your vehicle's operation.

Engine air filter

The engine air filter prevents dirt, dust, and other debris from entering the engine. A dirty or clogged engine air filter can reduce fuel efficiency, slow acceleration and damage the engine. Most vehicle manufacturers recommend changing the engine air filter every 20,000 to 30,000 km, depending on driving conditions.

Oil filter

The oil filter removes particles and debris from the oil that can damage the engine. A dirty oil filter can shorten engine life and, in extreme cases, can lead to engine failure. Most vehicle manufacturers recommend changing the oil filter with every oil change, which typically occurs every 7,500 to 10,000 km.

Fuel filter

The fuel filter prevents debris and other impurities from entering the engine through the fuel system. A dirty or clogged fuel filter can cause starting problems, loss of power and engine damage. Most vehicle manufacturers recommend changing the fuel filter every 30,000 to 50,000 km.

Cabin air filter

The cabin air filter filters the air entering the interior of the vehicle through the ventilation, heating and air conditioning system. It helps maintain air quality inside the vehicle by removing pollen, dust and other pollutants from the air. Most vehicle manufacturers recommend changing the cabin air filter every 15,000 to 30,000 km, depending on driving conditions.

How to change your vehicle filters?

Changing your vehicle's filters is a relatively simple process and can be done with a few basic tools. However, if you don't feel comfortable doing it yourself, it's always best to seek the help of a professional.

To change the engine air filter, you will need to open the hood of your vehicle and locate the air filter box. Remove the air filter box cover and remove the old filter. Insert the new filter and replace the cap.

The oil filter change is a little more complex. First, you will need to drain the old engine oil. Then remove the old oil filter with an oil filter wrench. Lubricate the new oil filter seal with a little new oil, then screw the new filter into place. Finally, refill the engine with new oil.

To change the fuel filter, you will need to relieve pressure in the fuel system, disconnect the fuel lines from the old filter, and remove the filter. Install the new filter and reconnect the fuel lines.

Changing the cabin air filter usually involves removing the glove box or other part of the instrument panel. Once you have access to the filter, simply remove the old filter and insert the new one.

In conclusion, regularly changing your vehicle's filters is an essential part of vehicle maintenance. By keeping your filters clean and in good condition, you can ensure your vehicle runs efficiently and extend the life of your engine.
