When we are talking about cars, the first thing, beside his look, is his engine. The engine of the car is like human heart, if it doesn't work well, the whole car doesn't work. So, the most important thing you do with your car is to go to regular inspections of engine parts by your car mechanic. If he says you need to replace some part, than you should do like that unless you want the more expensive costs.Oil filter is necessary for internal combustion engine to guarantee quality of oil. The car engine needs oil for oiling but sometimes oil became dirty because of the soot. Any dirtiness damages the engine, so the oil filter removes all foreign substances from the oil.Usually it is used one oil filter but in some cars there is also lubricating oil fine filter.Car owners need to change oil filter and oil after 20.000-30.000 km haul, but it is better to pay attention of the recommendation of the manufacturer. If you were wondering how it is to change oil filter there it is. The first thing mechanic do is to reduce the fuel system pressure and disconnect the battery before cleaning the fuel filter.

Oil Filter

Than he remove filter from the fuel system and spray with solvent cleaner. Then it needs to dry for one hour, then he reinstall it, reconnect the battery and start the engine. After that, he disconnect the negative terminal on the battery and turn off the car and open the hood.Then the mechanic locate the negative terminal on the battery and use a wrench to remove the cable and insert the cable on the side of the battery so that it does not accidentally come into contact with its pole. The negative pole is marked with a minus sign (-), and the positive pole with a plus sign (+). Then he finds the fuel filter somewhere along the fuel line between the engine and the fuel tank. The usual place is under the car, right next to the fuel pump. In some models, it is located in the engine compartment. He lift the car if necessary and he lace a bucket or container under the filter to trap fuel. It is necessary to disconnect the lugs that secure the fuel supply to the filter and remove the fuel lines. Using a wrench or hose clamp he remove the fuel supply from the filter and fill in the lines from the nozzles at both ends of the filter. By removing the lines, he need to be sure to turn them toward a bucket or container to catch any amount of dripping fuel. Pouring out any remaining fuel in the filter he ensures that there are not may be residual fuel in the filter.

Car oil filters

At the end of his work he sprays the filter with a pressurized carburetor cleaner. He attached the straw to the spray spout, then he spray inside each nozzle. When he discard the loose residue he dry the filter for an hour and than he carefully tap the filter on the side of the bucket he used to capture the spilled fuel. Then he let the spray and any debris fall out of each nozzle. After filter is drying for at least one hour he reinstall the filter by pushing the filter into its holder. He always make sure that the filter is back in the correct position by pulling the fuel supply back into each injector. Then cut the frogs that attach the lines to the nozzles back into place. Lower the car if necessary, then reconnect the battery and fuse. If the car is lifted, he needs to remove the racks, then lower it to the ground. Then he use a wrench to reconnect the cable to the negative terminal of the battery and replace the fuel pump fuse. Finally, he start the engine and check for fuel leaks. And now we will tell you the oil filters failure. If you see some of this signs make sure to take your vehicle to the mechanic. One of the most common sign is the grease under the engine is dribbling when the vehicle is parked. The second sign is when oil pressure indicator lights on the dashboard. Other signs can be swollen body of the component, than engine is overheated and oil consumption increased. If you are not sure, or you don't know the instruction, be sure that the maximal period of the component usage is 10000 – 15000 operational kilometers. The engine oil serves approximately the same time.


Top-quality synthetic oil alone can cost between $20 and $30 for a five-quart bottle, oil-change place charges $50 to $75 for oil and a filter replacement.
