Fuel filter "Ford Focus 2": device, signs of malfunction and replacement

The fuel filter has always been and is an integralpart of the fuel system of the car, which is installed absolutely on every modern machine from the conveyor. The main purpose of this part is to filter out dust and rust particles from the fuel, which flows through the mains to the combustion chamber of the engine. In the conditions of our roads, this detail is of particular importance, because the concentration of various deposits in domestic gasoline far exceeds normal values. If it were not for the fuel filter, Ford Focus 2 would have long ago demanded a major overhaul of the fuel system, which is a big expense.

And today we will consider the features of this element, and also learn how to replace it.

Fuel filter ("Ford Focus" 2 generations): device

In total, there are two types of datadevices. A filter of coarse and fine cleaning is distinguished. The latter is installed on all modern cars. As for the coarse filter, this element contains a part that consists of a brass mesh and a reflector. Due to this design, the filter does not allow the deposition of particles and particles larger than 0.1 millimeter. This type of device is designed for cleaning fuel from large impurities. The filter element itself is placed inside the glass, which is fixed to the body by pressure rings and bolts. The gap between the body and the said spare part is filled with a paronite gasket, and in the lower part of the device there is a so-called soot.

On fine-grained devices

As for the fine filters, theyare the second barrier to removing debris and contamination from the fuel. They are placed between the tank and the engine of the car. Most often this filter is wrapped in a nylon housing.

Due to this, the driver can easily determine the degree of contamination of this mechanism. In practice, the fine filter can hold particles up to 15 micrometers in size.

Signs indicating contamination of the device

In general, experts recommend a replacementfilters every 60 thousand kilometers. However, in fact it turns out that even the most qualitative element can not withstand 10-15 thousand kilometers of tests on our roads. Therefore, the figure of 60 thousand km is acceptable only for Germany, which sells gasoline, which meets the Euro 6 standard.

Also note that a clogged filter can causeto significant trouble. For example, this may be an additional load on the gasoline pump. If the time is not taken to replace the filter, the pump may soon fail. Also, the debris significantly aggravates the motor. And if the engine starts to stall, triple, and sometimes does not start, this is a clear sign that it's time to change the fuel filter. "Ford Focus" 1 and 2 generations, like all other foreign cars of the European market, has a similar process of replacing this element, so there is no difficulty in dismantling and installing the above-mentioned details.

Tools and materials

For the replacement, we will need tools such asa head for 8, a liter of diesel fuel, a container for draining the liquid, as well as the filter element itself. Filters (for the "Ford Focus" 2 generations, including) often cost about one thousand rubles. In this case, it is worth paying attention to the company-manufacturer. The original filters for "Focus" are produced by one company - Delphi. We will be guided by it.

How do I replace the fuel filter? "Ford Focus" 2 generation was distinguished by its diverse range of engines, which were present as diesel and gasoline units. However, the algorithm for their replacement is not different, so this manual can be used for any power plant.

How is the fuel filter replaced with a Ford Focus car?

For this we need to do the following operations. First remove the filter fuse. Next, start the engine and give him the opportunity to work at idle. We wait until the sensor on the instrument panel shows us the temperature of 80-90 degrees Celsius.

Then turn off the motor. To make sure that there is no pressure in the gasoline pipeline, turn the engine about 5 seconds with the starter. Next, remove the wire "mass" from the negative terminal of the battery and install the pump fuse. We drive the car to the observation deck or pit, place a small container under the bottom for drainage. It should be placed near the right rear wheel next to the tank - this is where the fuel filter is located. "Ford Focus" 2 generations remains stationary, and at this time we remove the connection of the pipelines of the system for catching gasoline vapors. Next, gently remove the feeding tube from the filter and remove the old contaminated mechanism. The remaining fuel is drained into the prepared container.

When installing a new filter, pay attention to the arrows indicated on its housing. They show the direction of the flow of fuel. Do not confuse them, otherwise all dirt will go into the engine!

Further assembly is carried out in reversesequence. After that, we connect the "mass" wire back to the negative terminal of the battery, start the engine and let it run for 30 seconds. Next, carefully check the connection of the tubes for leakage. Now you can safely start the operation of the car.

Conclusion

As you can see, the replacement of filters ("Ford Focus" 2ndgeneration is considered as an example) - this is not such a complicated process, which can be fully implemented by our own hands. Moreover, all manipulations can be made even on the road.
