Check of fuel system, replacement of the fuel filter. Operation of diesel model in the conditions of winter

The petrol engine

Gasoline is extremely inflammable, therefore at work with any components of fuel system it is necessary to accept special safety measures. Do not smoke, and do not come nearer to a place of work with open fire or the redurable not protected by a lamp shade. Do not make such works in the garages equipped with heating devices, working on natural gas (such, as водогреи, dryers, etc.). The working platform should be ventilated well. At gasoline hit on a skin immediately wash off its water with soap. At carrying out of any works with fuel system put on goggles and hold near at hand the fire extinguisher. In case of a gasoline spillage immediately wipe a pool, but do not hold the rags impregnated with gasoline in places where it can самовоспламениться.

1 If you have felt a smell of gasoline during movement or after the car has stood on the sun, it is necessary to check up a condition of all fuel system immediately.
2 Uncover a fuel tank and check up it on presence of damages and corrosion. The sealing insert on a cover should be whole. In case of presence of damages or corrosion replace a cover.
3 Survey inlet and returnable lines of fuel system on presence of cracks. Make sure that connections between lines of fuel system and system of injection of fuel, and also between lines of fuel system and the built in fuel filter not ослабли.

On the cars equipped with system of injection of fuel before to serve fuel hoses, it is necessary to dump pressure in system.

4 As some components of fuel system - for example, the fuel tank and some lines of fuel system - are in the bottom part of the car, they are easier for examining, when the car is raised лебедкой. If it is impossible, поддомкратьте the car and establish it on support.
5 On the raised car examine a fuel tank and a bulk mouth on presence of holes, cracks and other damages. Special attention give to a connection condition between a bulk mouth and a tank. Sometimes fuel leaks occur owing to easing of collars of fastening of a rubber mouth or because of damage of a material of a mouth. Examine all arms and tapes of fastening of a fuel tank to make sure that it is reliably strengthened on the car.

Never, under no circumstances, do not try to repair a fuel tank (excepting replacement of its rubber components). The flame of the welding device or any other open fire can easily lead to explosion of evaporations of gasoline in a tank.

6 Carefully check up all fuel hoses and the metal lines going from a tank on presence of weakened connections, twisting, signs of deterioration of materials of hoses and other damages. If necessary make repair or replace the damaged sections.

The diesel engine

Operation in winter conditions

7 In дизтопливо no additives are added. Kerosene addition is supposed – address to Specifications.
8 If the engine is not got owing to загустевания fuel, to start it very hard. For start:

a) Remove the fuel filter and heat up in a water bath while fuel does not become liquid., or replace its new.
b) Roll the car in heated garage.
c) Spray fuel system hot water.
d) Firm BOSCH delivers a diesel heater for additional installation. The electric heater is established in the additional pipeline to the fuel filter.

At all it is not necessary to warm up system of injection or a fuel tank a blowtorch or other similar adaptation in view of danger of explosion!

Removal of a sediment/replacement of the fuel filter

Regularly or at occurrence of a corresponding signal on the control panel from the filter water should leave. Water is formed, as a rule, in a fuel tank as a result of condensation or gets together with fuel on a filling station.

It will be necessary for carrying out of work for you:

- The manual vacuum pump with capacity for gathering of fuel from the filter, for example, KLANN LI-75200.
- Cartridge of the fuel filter.
- Sealing ring of a cover of the filter.
- Capacity for gathering of the water which are in the filter.

At hit of following diesel fuel on rubber details it is necessary to wipe the last at once (hoses of a cooling liquid). Otherwise fuel gradually leads to failure of rubber details.

Protect environment, at all do not pour out the fulfilled oil and do not delete it together with a household waste.


- Near to a workplace do not smoke, do not use open fire and heated or very hot subjects. There is a danger of occurrence of a fire! Keep in readiness the fire extinguisher.

- Watch necessarily sufficient ventilation of a workplace. Fuel steams are poisonous.

1 Switch off ignition.

2 Turn away a cover on the case of the fuel filter a head on 27 mm.

3 keep in readiness a rag. Take out an old fuel cartridge, wipe flowing down fuel.


1 Before installation of a new cartridge it is necessary to remove water from the case of the fuel filter. The usual manual vacuum pump, for example, KLANN LI-75200 is for this purpose necessary. Insert soaking up tube into the filter case.

Do not suppose liquid hit in the vacuum pump.

2 Manual pump pump out a liquid from the filter case in capacity.
3 Check up, whether there is no dirt in the filter case. If necessary wipe the case a rag.
4 Insert a new cartridge.
5 Screw a cover with a new sealing ring the moment 25 Nm.
6 Include for one minute ignition so, without starting the engine. The toplivopodkachivajushchy pump will join, will fill the fuel filter and will remove air from fuel system.
7 Visually check up tightness of fuel system, in particular, in places of connections of the fuel filter.
