Oil Filter Removal and Installation

The car’s oil filter removes dirt and contaminants from the oil, thereby preventing particles from entering the vehicle’s engine, which may damage the engine. Don’t wait for your oil lamp to light up; maintaining a routine maintenance schedule will keep your vehicle running smoothly for years to come. If you don’t want to go to a car mechanic for every small problem you encounter, then the question of how to replace the oil filter is very important. In addition to convenience, it also provides an opportunity to save time and money.


  1. Warm up the engine
  2. Open the engine fuel filler cap.
  3. After lifting the vehicle, remove the engine cover, remove the oil sump drain screw, then return the wire, and then release the old engine oil.
  4. Put down the vehicle and remove the old oil filter.


  1. Drain or suck up old engine oil
  2. Loosen the fixing screws and remove the old oil filter
  3. Apply a layer of oil on the sealing ring of the new oil filter
  4. Install the new oil filter and tighten the fixing screws


In the installation, it is strictly forbidden to tighten with tools, because if the sealing ring is under excessive force, the oil leakage of the machine will also occur. Then, what tools are used?

Oil-filter wrench

These filters are smooth cylindrical tanks with knurled bottoms, which are difficult to grasp, especially when oily.

  1. The loop of the chain is placed around the filter, and the chain is turned counterclockwise by hand until the chain wraps itself tightly around the filter. Then use a socket wrench or adjustable wrench to turn the hexagonal rod further in the same direction. This increases the tension in the chain, which bites into the soft metal housing of the oil filter, helping to prevent slippage.
  2. The other type uses a metal strap with both ends connected to the handle. Place the looped strap around the filter, and then turn the handle counterclockwise. This will apply tension on the strap to hold the filter tightly.
  3. The third general type of wrench uses a metal or plastic cup shaped like a socket. The cup is placed on one end of the filter and engages the knurling. Then use a socket or wrench to loosen the filter. Volkswagen Group and BMW need to use this wrench to remove their filters (or use the cover of the filter housing of a non-cylinder filter).
  4. the “claw” type wrenches manufactured by Sykes-Pickavantand other companies have three geared metal pins and accommodate (usually) a 3/8-inch ratchet screwdriver. Hold the filter body more tightly. This type is very effective on tight filters and is more suitable for narrow spaces than belt or chain filters.

How to Change Oil Filter? 4 Steps

Step 1: Drain the waste engine oil, first drain the waste engine oil in the oil tank, place the old oil container under the oil pan, open the drain bolt, and drain the waste engine oil. When draining the oil, try to let the oil drip for a period of time to ensure that the waste oil is drained cleanly. (The oil will produce a lot of impurities through use. If it is not cleanly discharged when changing, it will easily block the oil circuit, resulting in poor oil supply and wear of structural parts)

Step 2: Remove the old oil filter element, move the old oil container under the machine filter, and remove the old filter element. Be careful not to stain the inside of the machine with waste oil.

Step 3: the preparation work before the installation of the oil filter element.

In this step, I will tell you that you do not need to fill the filter element with oil before replacing the new machine filter. There are two ways to install the oil filter element, the common one is vertical installation, and many small excavated machine filters are installed horizontally. The installation method is different, so there are two situations for filling with oil:

  1. Let’s talk about the vertically installed oil filter element, which is connected to the oil pump through an oil pipe. Generally, it is recommended that the user replace the machine filter and fill the filter element with oil. If the filter of the new machine is not filled with oil, air resistance will be generated inside the new filter element, which will cause a short-term lack of oil lubrication inside the machine when the car is started, which will cause structural parts to wear. The advantage of the vertical installation method is that the filter element has better sealing performance and there is little oil leakage.
  2. Besides, the horizontally installed oil filter element is directly connected to the oil pump without passing through the oil pipe. This design does not generate air resistance inside the filter when filling the oil tank with oil. The filter element does not need to be added before installation. Injecting oil, while injecting new oil into the oil tank, the oil filter element can be directly filled with oil.

Step 4: Install the new oil filter

Check the oil outlet where the oil filter element is installed, and clean up the dirt and residual waste oil. Before installation, put a seal ring on the oil outlet, and then slowly screw on the new filter. Do not tighten the filter too tightly. Generally, after tightening by hand, use a wrench to tighten 3/4 The circle will do. Note that when installing a new filter element, do not use a wrench to tighten it too hard, otherwise it will easily damage the sealing ring inside the filter element, resulting in poor sealing effect and no filtering effect!

Then all that remains is to refuel the car and start the engine to make sure the oil lamp goes out!

Today’s engines are high-tech miracles. But they still need protection to avoid the severe test of an emergency stop, dusty or muddy roads, extreme temperature changes, and other harsh driving conditions. Oil filters play a key role in providing protection by helping prevent dust, metal chips, and sludge from entering the oil and expensive engines. Therefore, experts recommend replacing the vehicle’s oil and oil filter every six months or between 5,000 to 8,000 kilometers (whichever comes first) to protect the engine to the greatest extent.
