Note. At atmosphere temperature below 0 °С clogging symptoms
can be caused by water freezing in fuel system. When detecting
water in fuel purge fuel and rinse fuel tanks with pure fuel and
fine fuel filters are to be replaced.
Leakage in couplings should be eliminated by replacing faulty
components.
Upon completion of any fuel system maintenance operations,
related to tightening of connections, removal or replacement of parts and
assemblies, the system hermetic-tightness must be checked as follows:
– make sure the filler neck plug is securely tightened;
– fuel tubes shall be installed until “click” of the quick coupler’s
locking spring;
– start the engine running idle and check the system visually. Fuel
leaks or the fuel system components wetting may not be allowed.
In the course of vehicle operation, pay attention to the following:
– a strong smell of gasoline within the vehicle’s salon, engine
compartment in locations of passage of fuel and steam hoses and
tubes, if this occurs — check the hermetic-tightness of joints, con-
dition of the adsorption container (absence of cracks and damage,
serviceability of the adsorption container’s purge valve);
– operability of the evaporative emission control system (the
absorber and the fuel tank valve). Any failure of these elements leads
to fuel supply system failures. Damaged components shall be replaced.
Accelerator pedal drive. The motor vehicle is equipped with
an accelerator pedal electronic module. Accelerator pedal is made
of plastic. Full pedal stroke equals 48,7 mm and is provided with
stable design and is not regulated.
Air filter. After every 30,000 km of total kilometres logged
and after engine capacity reduction, replace filter element.
The filter element shall be replaced as follows:
– loosen collars and remove angle, and resonator hoses from
air filter;
– unscrew collar nut 4 (Fig. 9.9), remove collar and air filter;
– unscrew nut 7 and take cover 1 with the filter cartridge 5 out
of the filter housing;
– unscrew nut 6 and remove filter element;
– install a new filtering element, compose and install air filter.
