Oil filter: where it is, how to choose and replace

An oil filter is an essential component of any vehicle. Its task is the cleaning of oil that lubricates the engine from impurities and debris. It is important to choose only high-quality products and timely replace them in accordance with technical regulations. How does the best oil filter work? Where is he located? When do I need to replace the filter to ensure the smooth operation of the engine? The answers to these questions are in our article today.

A modern car filter consists of the following elements:

1. The filter element. The main part of the filter. Made of porous material, paper or felt. Delays particles of garbage that are caught in oil. Depending on the model and manufacturer of the filter, the height and level of the filter element may change, but the diameter, as a rule, remains unchanged.

2. Bypass valve. It is necessary so that during the start of the ICE in the winter the unfinished part of the lubricant enters the engine, bypassing the filter element. Although the motor will run for a short period of time on crude oil, it is better than working without it at all.

3. Anti-drain valve. It is a rubber ring with a hole in the middle, which prevents the leakage of oil from the filter in the event of a decrease in its pressure in the motor. This valve must maintain elasticity regardless of temperature and fit snugly against the filter housing.

4. The filter cover. It is tightly connected to the body by welding or rolling. The second option is preferable, since the welding joint in some cases can lose tightness and lead to leaks.

5. Sealant. It has the appearance of a rubber ring, which is installed on the neck of the oil filter and serves to seal the junction of the filter and the engine. The principle of the filter is simple. The oil circulating in the internal combustion engine passes through the filter element of the filter and is cleaned of debris, metal chips and other possible contaminants that have got into it.

There is no single standard for placing an oil filter in a car. Each manufacturer independently decides where to install this part on the engine. In addition, the location of the engine is affected by the layout of the engine, the make of the car, and whether it is front- or rear-wheel drive.

Nevertheless, given the specifics of the filter, it should be placed as close to the bottom of the power unit as possible. Therefore, you need to look for it in your car at the bottom of the engine near the crankcase. It is usually located in such a way as to provide access for replacement from the top of the machine, without the need to lift it onto a flyover.

If you have a front-wheel drive car with a transverse engine layout, the filter will be located in front of the engine (closest to you) in the area of ​​the left headlight closer to the timing belt . However, other accommodation options are possible. Look for a small cylinder with a threaded connection, which differs in color from the engine (filters are usually painted in bright colors). Most likely, this will be the oil filter.
