Repair and car operation

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

Resulted below check of levels of a liquid should be made weekly, or through each 400 km (250 miles) run. Additional checks of levels of liquids are made within the limits of resulted below procedures of special service. Without dependence from terms of carrying out of checks pay attention to traces of leaks of a liquid under the car which can be the certificate of the malfunction which are subject to immediate elimination.

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

For carrying out of 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 probeа, inserted into a special tube and a reaching bottom of the pallet картера the engine.

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

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

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

Level of impellent oil constantly should be supported between marks in an edge measuring probeа - for lifting of level from mark ADD to mark FULL it is required about 1 l of oil.

Do not overflow the engine, pouring too much oil as it is fraught with failure of epiploons, occurrence of leaks of oil and забрасыванием 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 oil passage it is necessary to take advantage of 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 - preliminary necessarily wipe a cover and surrounding mouth a surface in order to avoid hit in the dirt engine.

Check of level of impellent oil is the important preventive step of maintenance service of the car. Constant falling of level of oil speaks about presence of its leaks which reason defects of epiploons and linings, deterioration of piston rings or directing plugs of valves can be. If oil has a dairy-shaped consistence or at it obviously there is a water, it is quite probable that defects of a lining (ок) heads (ок) cylinders or a crack in block moulding 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 probe at check of level of oil, remove from it oil traces big and index fingers. If on probe have stuck small metal sawdust, oil is necessary to replace (Section Change of impellent oil and the oil filter (each 4800 km (3000 miles) run or times in 3 months)).

Engine cooler

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

All considered in the given Management of the car are equipped by 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 overheat of the engine the cooler is superseded through the valve in a cover of a radiator and on a hose arrives in a broad tank. In process of cooling of the engine the cooler is automatically poured from a tank back in a radiator that allows to support automatically its demanded level in system.

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

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

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

After a trial trip once again check up 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 take advantage of pure water simply. However, often repeating regular additives of water shortly will lead inadmissible разбавлению 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 take advantage of an empty package from under milk. It is not necessary to add in a ready mix of an additive and ингибиторы corrosion.

If cooler level falls constantly, it can be the certificate of leaks in system. Check up on presence of signs of leaks a radiator, hoses, a cover of a jellied mouth, drain stoppers and the water pump (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 out signs of leaks, it is necessary to make check of a cover of a radiator by pressure - address on a car repair shop.

If there is a necessity for removal of a cover of a radiator, preliminary wait full cooling of the engine, then wrap up a cover a thick layer of rags and slowly turn away it to the first emphasis. In case from under covers steam starts to be pulled out, allow to the engine to cool down still, then uncover.

Check also a cooler condition. The cooler should be rather transparent. If it has red-brown colour of a rust, it is necessary to empty, wash out and fill system with a fresh mix. As a part of a mix ингибитор corrosion in due course loses the protective properties, cooler change should be made through provided by the schedule of routine maintenance intervals without dependence from its condition.

Liquid of washing of a windscreen

The liquid for washing of a windscreen of the car is filled in in the tank made of plastic also located in an impellent compartment.

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

In areas with a temperate climate usual water, however its quantity can be applied to windscreen washing in the tank should not exceed 2/3 volumes of the last for the purpose of secure on a case of expansion of water at 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 at using washers in cold weather preliminary include heating (having blown) in glasses.

Battery electrolit

The majority of models of cars considered in a given Management are equipped by storage batteries tight (not including ventilating apertures) 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 by 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.

The liquid is well visible through translucent walls of the plastic tank. If liquid level has inadmissibly fallen before uncovering the tank for the purpose of product долива, preliminary carefully wipe its top part pure rags in order to avoid dirt hit in hydraulic system (brake/coupling).

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

At liquid addition cautiously add it in the tank, trying to avoid hit of splashes on surrounding painted surfaces. Use only a 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 in the beginning of the given Chapter or the car operation manual).

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

At the given stage the liquid and the main cylinder can be checked up on presence of traces of pollution. In case of detection of particles of a dirt, drops of water or a deposit the system should be emptied and filled by a fresh liquid.

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

Level of a brake liquid in the main cylinder will fall slightly in process of deterioration brake колодок and boots during normal operation of the car as thus there is fuller 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 up a condition of all brake lines and штуцерных connections (the Section Check of a condition of brake mechanisms (each 12 000 km (7500 miles) run more in detail see, or time in 6 months)).

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