Usually, it is necessary to replace oil in the engine and the oil filter itself at least every six months of its operation or after every twelve thousand kilometers of the vehicle mileage. It is quite possible to spend the work of this type, however, not all drivers are known how to do it right. This topic will be devoted to our article.

Where is the oil filter

Oil filter is part of a vehicle lubrication system. As a rule, the oil filter is located at the bottom of the motor near the pallet. It is often mounted on the oil pump housing. The oil filter is able to capture and delay the worn out products, thereby cleaning the engine oil from them.

As for the engine oil, it is capable of not only to lubricate the parts, but and wash off the microscopic chips and the nagar, which are inevitably formed during the operation of each mechanism. If not cleaning the oil, abrasive particles will scratch the working coatings of rubbing elements.

It is believed that the car oil filter created in 1923 an American scientist Bobby Evans and called him "Purlator".

In order to attach a filter, a predicted hollow rod having an outer thread, which coincides with the inner thread with the outlet of the filter. Inside the case, the filter part, bypass valve and check valve are mounted. Whatever the oil pump is tightly adjacent to the body, a sealing rubber ring is mounted in the end flat part of the filter around the outlet. To unscrew the filter, use a special segment or belt key, which can be bought in specialized parts for car spare parts.

Operation principle of oil filter

After the motor is running, oil in the oil filter is started from the pump under pressure, by means of small inlet inlet on the end filter department located in a circle.

Under the influence of pressure, the bypass valve begins to skip oil through the hole between the filtering element and the filter housing. When the oil is seeping through it, it is filtered and falls into the inside of the oil filter. After it passed the outlet, its movement continues on rubbing items and on the lubrication system. For the most part of modern vehicles, use a filter piece of paper, folded many times.

If the motor oil thickness is too high or the filter element is dirty, the bypass valve in the filter opens, which allows oil to connect the filter part and take place without cleaning the filter on the entire system. The bypass valve is provided, so that the oil starvation of the motor would not begin.

When the motor is disabled, the pump stops supplying the oil into the filter. The check valve closes that it does not allow to flow out oil from the lubricant system to the motor crankcase pallet.

Oil filter, how to choose

When buying a new filter, it is also necessary to purchase a container with butter, because after replacing the oil filter, oil must be addressed to the motor. On this purchase should not save, since the protection of the vehicle from the wear of the elements depends on the quality of the filter and oil. It is advisable to choose those stamps that the manufacturer of your car recommends. Types of oil filters There are many. You can pre-consult with a specialist who helps you choose the best option.

Helper tools in work

To replace the oil filter, you will need the following tools and materials, and, of course, a little patience.

1. Kanistra to drain the exhaust oil.

2. It is advisable to purchase rubber gloves to protect your hands from lubricating on them.

3. If the drain plug is tightened very much, it is necessary to use a special gate.

4. Replaceable end head, the size of which coincides with the size of the plum cork.

5. Ribbon key, which is used in the case of limited access to the oil full-flow filter.

6. The puller for such a filter.

After the toolkit for the work is prepared, provide free access to the vehicle pallet. To do this, it is desirable to drive a car on the overpass, however, if you do not have such an opportunity, use the jack and install the machine on the backups. It is very important to make sure that the car is securely installed in a raised position and only then you can proceed to work.

Replacing the oil filter, step by step

Before you climb the vehicle, you need to start the motor and warm it up to the optimal operating temperature, since hot oil has better fluidity, and therefore the sludge and precipitate will be released in the maximum amount.

After performing the actions listed above, you can easily climb the vehicle and perform the required tasks. First you need to pay attention to the oil filter, drain plug and crankcase pallet. Do not forget that some parts of the car will still be hot, for this reason, it is necessary to work as much as possible, so that it would not burn.

However, you should not worry, since the replacement of the oil filter is at least a rather responsible moment, but still simple. Next, you need to install a drainage container under the pallet of the crankcase and turn the drain plug, which is located in the lower parts of the pallet. Now we need to wait for the moment when the lubricant is completely departed from the motor. Before tightening the cork back, you should wipe it from the remnants of the dirt with a clean cloth. It is necessary for the fact that dust and dirt did not get into new oil. Also, it is necessary to wipe around the drain hole of the pallet surface.

Now, move closer capacity to the device that is subject to replacement. Weaken the filter in any convenient way and turn it out of the block together with the rubber seal. Do not be discouraged if in the process of performing work you damage the item, since it will still have to change it. The remains of the oil from the filter are sent to the drain container.

Now we take a clean cloth and process the planting surface on the block. It's time to make sure that the new filter part is absolutely signed with a vehicle.

With clean engine oil, we lubricate the rubber gasket of the new part, after which we screw it into the engine, oriented, while on the arrow indication of rotation on the housing. You should not use the keys to tighten the filter in order not to damage the gasket.

Now you can put a vehicle in a normal position, but do not forget to remove the drain container and tools.

Oil change, work step in stages

At the last stage of this procedure, you need to pour new oil. To do this, follow the following series of actions:

1. It is necessary to remove the cover from the filling neck of the engine oil.

2. Insert the funnel into the foster of the neck and pour about three liters of new oil.

3. We are waiting for a few minutes while it stalks into the pallet.

4. Check the oil level with a special measuring probe. If it is not enough, we fill the oil to the desired mark.

5. We bring the engine and let him work for a while, after which, the wasting it.

6. Now it is necessary to look at the bottom of the vehicle and make sure that oil does not flow out from the drain plug and the full-flow filter. If you detect leakage, you need to tighten the desired item more tight.

7. Check the level again.

It is very important, not to pour the fusion waste oil to the ground or into the sewer system, it is desirable to pass it into a specialized receiving point. As you have already been convinced, each car enthusiast can replace the oil filter on its own forces. In fact, it is very simple, however, requires some patience. Good luck.
