Repair and car operation

Checks of levels of liquids (each 400 km (250 miles) run or weekly)

Given below check of levels of liquid should be made weekly, or through each 400 km (250 miles) run. Additional checks of levels of liquids are made within given below procedures of special service. Regardless of terms of carrying out checks pay attention to traces of leakages of liquid under the car which can be the testimony of the malfunction which is subject to immediate elimination.

Liquids are the integral and major component providing normal functioning of systems of greasing, cooling, braking, coupling and windscreen washing. In view of that liquids during normal operation of the car are subject to a gradual razzhizheniye and pollution, it is necessary to make their replacement periodically. Before starting replacement or liquid addition in any of listed below components familiarize with subsection requirements Recommended greasings and liquids of Specifications at the beginning of this Chapter.

For carrying out check of levels of liquids the car should be parked on an equal horizontal platform.

Impellent oil

Check of level of impellent oil is made by means of measuring щупа, inserted into a special tube and reaching bottom of the pallet of a case of the engine.

Shchup of measurement of level of impellent oil on the V8 models is on a forward wall of the engine, behind a radiator.

Measurement of level of impellent oil is made before the trip first in this day or later not less than 15 mines after engine switching off. Level check immediately after a stop of the engine will yield incorrect result as the part of oil will be thus in the top part of the engine.

Take щуп from a tube and dry wipe its edge pure rags or a paper towel. Completely enter щуп back into a tube and again take it. Estimate height of the site of an edge moistened with oil щупа. In case of need make having added oils, having finished it to the level being between marks of ADD to (Add) and FULL (Full) on a measuring site of an edge щупа.

Level of impellent oil constantly should be supported between marks in an edge measuring щупа - level lifting from ADD mark to a mark of FULL needs about 1 l of oil.

Do not overflow the engine, pouring too much oil as it is fraught with failure of epiploons, emergence of leakages of oil and a pelting of spark plugs.

Having added oils in the engine it is made after removal of a cover of the jellied mouth located on a cover of a head of cylinders. In order to avoid the passage of oil it is necessary to use the butterdish equipped with a long nouse or a funnel.

Oil is filled in in the engine after removal of a cover of the jellied mouth located on a cover of a head of cylinders - previously surely wipe a cover and surrounding mouth a surface in order to avoid hit in the dirt engine.

Check of level of impellent oil is an important preventive step of maintenance of the car. Continuous falling of level of oil speaks about existence of its leaks which reason defects of epiploons and laying, wear of piston rings or directing plugs of valves can be. If oil has a dairy and figurative consistence or at it obviously there is a water, it is quite probable that defects of laying (ok) heads (ok) cylinders or a crack in block molding take place. It is necessary to make check of a condition of the engine immediately. Except level it is necessary to check as well an oil condition. The first time taking measuring щуп at check of level of oil, remove from it oil traces big and index fingers. If on щуп small metal sawdust stuck, oil is necessary to replace (The section Change of impellent oil and the oil filter (each 4800 km (3000 miles) run or times in 3 months)).

Engine cooler

Do not allow antifreeze hit on open sites of a body and the painted surfaces of the car. Casually got splashes immediately wash away a plentiful quantity of water. Do not store new and do not throw the merged cooler in the places available to children and animals - the sweetish smell of antifreeze can easily draw of them attention. Hit even insignificant quantity of a cooler in an organism can lead to a lethal outcome! Immediately wipe spilled on a garage floor a cooler. Store antifreeze in tightly closed container and immediately eliminate all found leakages of system of cooling.

All considered in this Management of the car are equipped with system of cooling of compensatory type working at superfluous pressure. The broad tank executed from white plastic is located in an impellent compartment and connected by a hose to a cover of a jellied mouth of a radiator. At an engine overheat the cooler is forced out via the valve in a cover of a radiator and on a hose arrives in a broad tank. In process of engine cooling the cooler is automatically poured from a tank back in a radiator that allows to support automatically level demanded it in system.

The broad tank of system is located in the right back corner of an impellent compartment - try to support constantly cooler level near a mark of FULL in a tank wall.

Check of level of liquid in a broad tank of system of cooling should be made regularly.

Do not uncover a tank for check of level of liquid in it at the hot engine. Cooler level in a broad tank changes with change of temperature of the engine. At the cold engine level of a cooler should be slightly above a mark of ADD to (Add) on a tank wall. After an engine warming up liquid level in a tank should rise, having come nearer to FULL mark (Full). If these requirements are not carried out, wait engine cooling, then uncover a tank and add in it necessary for correction of level number of 50 % of a mix of antifreeze on base этиленгликоля with water.

After a trial trip once again check cooler level in a tank. If for reduction of level of a cooler to demanded value it is required only insignificant having added, it is possible to use pure water simply. However, often repeating regular additives of water shortly will lead to an inadmissible razbavleniye of antifreeze. Thus, with a view of maintenance of demanded structure of a cooler, it is recommended to make having added correctly grouped mix. For formation of demanded structure of a mix it is convenient to use an empty package from under milk. It is not necessary to add in a ready mix of an additive and corrosion inhibitors.

If level of a cooler falls constantly, it can be the certificate of leaks in system. Check on existence of signs of leaks a radiator, hoses, a cover of a jellied mouth, drain jams and the water pump (The section Check of serviceability of system of cooling (each 4800 km (3000 miles) run or times in 3 months)). If it is not possible to find signs of leaks, it is necessary to make check of a cover of a radiator by pressure - address on car repair shop.

If there is a need for removal of a cover of a radiator, previously wait complete cooling of the engine, then wrap up a cover a thick layer of rags and slowly unscrew it to the first emphasis. In case from under covers steam starts to escape, let's to the engine cool down still, then uncover.

Check also a cooler condition. The cooler should be rather transparent. If it has red-brown color of a rust, it is necessary to empty, wash out and fill system with a fresh mix. As inhibitor of corrosion a part of a mix loses over time the protective properties, change of a cooler should be made through provided by the schedule of routine maintenance intervals regardless of its condition.

Liquid of washing of a windscreen

Liquid for washing of a windscreen of the car is filled in in the tank made of plastic which has been also located in an impellent compartment.

The tank of liquid of washing of a windscreen is located in the left part of an impellent compartment - shares of liquid can be made after removal of a folding cover.

In areas with a temperate climate usual water, however quantity can be applied to washing of a windscreen it in the tank should not exceed 2/3 volumes of the last for the purpose of secure on a case of expansion of water when freezing during, for example, night cold snap. In areas with a frigid climate in the tank special antifreeze should refuel - ask in shops of automobile accessories, - reducing a liquid freezing point. Mix antifreeze with water in the proportions specified on packing.

At all do not apply the antifreeze intended for use in system of cooling as it is aggressive in relation to the painted surfaces!

In order to avoid a glass icing when using washers in cold weather previously include heating (having blown) in glasses.

Battery electrolit

The majority of models of cars considered in this Management are equipped with storage batteries tight (without considering ventilating openings) type and have no jellied covers. Carrying out regular долива waters in such batteries is not required. If for any reason your car is equipped with the battery of demanding service of type, it is necessary to remove regularly from it the top covers and to check electrolit level in banks. Especially important such checks become in a warm season.

Brake liquid and hydraulic liquid of coupling

The main brake cylinder (and if it is provided, the coupling cylinder) is fixed in the left top corner of a partition of an impellent compartment.

Liquid is well visible through translucent walls of the plastic tank. If liquid level inadmissibly fell before uncovering the tank for the purpose of work долива, previously carefully wipe its top part pure rags in order to avoid dirt hit in hydraulic system (brake / couplings).

Level of brake liquid can be easily checked through translucent walls of the tank - for work долива remove covers.

At liquid addition carefully add it in the tank, trying to avoid hit of splashes on the surrounding painted surfaces. Use only liquid of a demanded grade as mixing of two various types of liquids can lead to irreversible damage of system (see subsection Recommended oils and greasings of Specifications at the beginning of this Chapter or the operation manual on the car).

Hit of brake liquid in eyes can lead to a serious trauma, besides, liquid is aggressive in relation to the painted surfaces of the car. Therefore at the treatment of her observe extreme care. Do not use the brake liquid stored in open container more than one year - liquid is extremely hygroscopic (possesses ability to absorb moisture from the atmosphere). The excessive content in brake liquid of moisture is fraught with dangerous decrease in efficiency of braking.

At this stage liquid and the main cylinder can be checked on existence of traces of pollution. In case of detection of particles of dirt, water or deposit drops the system should be emptied and filled with fresh liquid.

After tank filling to demanded level take care of a reliable tightening of its cover/stopper for the purpose of prevention of leaks.

Level of brake liquid in the main cylinder will fall slightly in process of wear of brake shoes and boots during normal operation of the car as thus there is more complete replacement of pistons of supports / wheel cylinders. If for maintenance of demanded level in the main cylinder it is required regular and frequent having added liquids, it is a leak sign in the system which source should be immediately revealed and liquidated. Carefully check a condition of all brake lines and shtutserny connections (for more details see. The section Check of a condition of brake mechanisms (each 12 000 km (7500 miles) run, or times in 6 months)).

If during check of level of liquid of the main cylinder it is found out that one or both tanks are empty or nearly are empty, the brake system should be pumped over (Head Brake system).
