Check of levels of liquids, control of leaks
Liquids are the integral component of lubrication systems, coolings, brake and systems of washing of a windshield. In view of a gradual expense and/or pollution of liquids in the course of normal operation of the car, they should be replaced periodically. Study the Section "Types and Volumes of the Applied Greasings and Liquids" in Specifications before starting a liquid dolivaniye in any of listed a component.
Visual control of leaks
Check of level of oil probe
Check of level of oil is important preventive procedure. Continuous falling of level of oil indicates or existence of its leaks through the damaged epiploons or the weakened connections, or its burning out (internal leaks through worn-out piston rings or via the directing plugs of valves). Besides, it is necessary to pay attention and to a condition of the oil. If oil has dairy color or in its structure it is possible to notice water drops, it indicates possible violation of tightness of laying of a head of cylinders or existence of a crack in a head or the block of cylinders. In this case the engine should be repaired immediately. Run every time at measurement of level of oil before rubbing of an edge of the probe over it big and index hand fingers. If thus the particles of dirt or metal particles which stuck to the probe are found, oil should be replaced (address to the Section Replacement of Motive Oil and Oil Filter).
Consumption of motive oil
Max. 0.8 l / 1000 km, depending on style of driving.
The oil consumption can be defined by the engine only after passing of a long distance. In the period of a running in it can exceed the given value. The frequent movement with high turns of the engine conducts to increase in a consumption of oil.
Cooling liquid of the engine
All cars considered in this manual are equipped with the cooling system with excessive pressure of compensation type. The white plastic broad tank is located in a motive compartment and connected by a hose to a radiator. In process of an engine warming up in the course of its work the extending liquid fills a tank. When cooling the engine liquid automatically comes back to the cooling system that provides maintenance of constant level.
Check of level of liquid in the tank has to be made regularly, at strictly horizontal position of the car and the switched-off engine.
Banish the car and again measure liquid level. If to the necessary level it is required to add only a small amount, it is possible to use clear water. However frequent additions of water will dilute antifreeze. To provide a normal ratio (40%/60%) of antifreeze and water, always add to the necessary level the demanded mix of the antifreeze specified in Specifications on the basis of ethylene glycol and water.
Fill in large volume of cold cooling liquid only at the cold engine to avoid damages of the engine.
If the level of liquid falls regularly, in system leak existence is possible. Examine a radiator, hoses, a cover of a jellied mouth, drain traffic jams and the water pump (address to the Section Check of a State and Replacement of Hoses of a Motive Compartment, localization of leaks). If leaks it is not revealed, make check of tightness of a cover of a broad tank and radiator in conditions HUNDRED.
If you need to uncover, wait until the engine completely cools down, then wrap up a piece of thick rags round a cover and turn off it to the first emphasis. If thus from under a cover steam or liquid starts escaping, let's the engine cool down a little more, and only then uncover.
It is necessary to check a condition of liquid also. It has to be rather pure. If liquid has brown or rusty color, it is necessary to merge, wash out it system and to fill it with new mix. Even if liquid looks normally, the corrosion inhibitors which are its part lose over time the efficiency therefore it should be replaced through certain periods.
For check of frost resistance of cooling liquid it is necessary to use the areometer (address to an illustration and Specifications).
Level of brake fluid is checked visually, on tags on the plastic tank installed on the main cylinder. At the closed cover the level of brake fluid has to be between marks of MAX and Min.Esli level below admissible, at first wipe top of the tank and a cover pure rags to prevent hit of dirt in system after removal of a cover. Add to the necessary level the recommended liquid, but do not pour.
Until it is uncovered the tank, check liquid and the tank of the main cylinder for existence of pollution. If at it there are particles of a rust, dirt or a drop of water, liquid from system should be merged and filled in the new.
After addition of the tank to the necessary level make sure that the cover is established exactly, in order to avoid leak of liquid and/or hit of dirt.
Liquid level in the main cylinder will fall slightly as a result of wear of frictional overlays of brake shoes. There is no need to add it until level remains near a tag of "MIN"; it will rise after replacement of slips. Very low level can indicate wear of brake shoes. Check them for wear existence (address to the Section of Check of brake system. Adjustment of the parking brake).
If the level of brake fluid constantly falls, immediately check all system for existence of leaks. Survey brake lines, hoses and nipple connections, together with supports, wheel cylinders and the main cylinder (address to Sections of Check of brake system. Adjustment of the parking brake, Check of a state and replacement of hoses of a motive compartment, localization of leaks).
If when checking level of liquid the tank is empty or nearly is empty, the brake system has to be checked for existence of leaks and is pumped over (address to the Head Brake system).
The tank of hydraulic system of the amplifier of a steering is in back part of a motive compartment. Address to the Section Check of Level of Liquid of System of Hydrostrengthening of a Wheel.
Windshield washer liquid
Easily we ignite a concentrate of steklomoyushchy means.
At the address with a concentrate of steklomoyushchy means use of fire opened a flame and smoking are forbidden.
If necessary add mix from a concentrate for a sink of glasses and drinking water.
Capacity of the tank is specified in Specifications.
In areas with a temperate climate the system can be filled with usual water, but it is recommended to add to water means for washing of glasses. The tank has to be filled no more, than on two thirds that there was a free space on a case of expansion of water when freezing. In areas with cold climatic conditions it is necessary to use the special antifreeze for washing of a windshield reducing a liquid freezing point which can be got in any shop of automobile accessories. Usually it is on sale in the concentrated or ready look. If you got the concentrated antifreeze, mix it with water according to the instruction of the producer on packing.
