Check of levels of liquids

Various liquids play a role of working bodies in lubrication systems, coolings, heating and air conditioning, braking, washing of glasses, etc. In view of the fact that all liquids are subject to fluidifying and development eventually, and also during normal functioning of systems gradually become soiled, it is necessary to make their full replacement periodically. Before starting adjustment of level or replacement, study the list of the grades of liquids recommended for use in the car.

When checking levels of liquids the car has to be parked on the flat horizontal platform, whenever possible with a hard coating.


Motive oil

 PERFORMANCE ORDER

1. Check of level of motive oil is made by means of the measuring probe passed throughout the directing tube and the pallet of its case lowered in the engine to the bottom. On all models the measuring probe is located in a forward part of the power unit.

2. Check of level of oil has to be made before the first in the present day trip, or not less than 5 minutes later after an engine stop. If to execute check immediately after switching off of the engine, its results will adequately not reflect a situation as a part of oil will be distributed on internal galleries and components of the engine.

3. Take the measuring probe from the directing tube and dry wipe its edge with pure rags or a paper towel. Insert the probe back into a tube against the stop, then again take. Having examined a probe edge, estimate the size of the site moistened with oil. Level of oil has to be between the top and lower marks in a probe edge. In case of need add the corresponding amount of oil of the required grade in the engine.

4. Rise in level from the lower (MIN) mark in the probe to top (MOVE) requires about one liter of oil. Lowering of level out of limits of the lower bound of admissible range leads to development of oil starvation of the engine and fraught with serious mechanical damages of the last. Try not to pour also oil above the top mark as it can lead to a pelting of spark plugs or failure of epiploons of the power unit as a result of excessive increase in pressure.

5. To fill in oil in the engine it is necessary to uncover equipped with a carving of a jellied mouth. In order to avoid spraying of oil during its gas station in the engine use a funnel, or a butterdish with a long nose. Having filled in oil, screw and strongly tighten a cover of a jellied mouth, then start the engine and attentively examine a drain stopper and the surface of an oil filter interfaced to the block on existence of signs of leaks. Kill the engine, wait about 5 minutes during which oil will merge in the pallet, then double-check its level.

6. Check of level of engine oil is the important preventive procedure of service of the engine. Continuous decrease in level demonstrates existence of leak of oil as a result of failure of epiploons, damage of sealing laying, wear of piston rings or the directing plugs of valves. If oil on color or a consistence reminds milk, or at it there are water drops, it speaks about possible damage of laying of a head of cylinders, or formation of cracks to a body of a head(s) or the block. Check has to be made immediately. During measurement of level of oil always check also its state. Big and index fingers remove oil traces from a probe edge, - in case of presence at it of small metal particles oil is subject to replacement (see the Section Replacement of Motive Oil and Oil Filter).


Cooling liquid of the engine

Do not allow hit of antifreeze on open parts of the body and the painted surfaces of the car. Immediately wash away casual splashes a plentiful amount of water. Remember that antifreeze is extremely toxic liquid and its hit in an organism even in small amounts is fraught with the most serious consequences, up to a lethal outcome. Never leave antifreeze stored in leaky closed container, immediately collect the cooling liquid spilled on a floor. Remember that the sweetish smell of antifreeze can draw to itself attention of children and animals. About ways utilization of the fulfilled cooling liquid consult with local authorities,-.во many regions of the world special points on different reception of working off are equipped. Do not merge old cooling liquid in the sewerage and on the earth at all!

Recently nontoxical grades of antifreeze are developed, nevertheless, they also had to be utilized in an organized order.


 PERFORMANCE ORDER

1. All models of cars described in the present manual are equipped with the cooling system of compensation type working with an excessive pressure. The broad tank of the cooling system made of translucent plastic is located in a motive compartment and connected by an overflow hose to the basis of a jellied mouth of a radiator. At an engine overheat cooling liquid extends, and its surplus flows via the valve which is built in in a cover of a jellied mouth of a radiator, in a broad tank. In process of cooling, liquid comes back on a hose in a radiator that allows to support constantly normal its level in system.

Do not uncover a jellied mouth of a radiator at the hot engine at all!

2. Level of cooling liquid in a broad tank is checked on a regular basis and has to be between the marks LOW and FULL in translucent walls of a tank. It is necessary to remember that the level of liquid depends on its temperature therefore it has to be in a cold state only slightly above the lower mark, and after warming up of the engine - to rise to the mark FULL. In case of need make the corresponding adjustment, having added in a tank through a mouth the required quantity is fresher than mix.

For adjustment of level of liquid use only the required structure mix of ethylene glycol and the distilled water (about 50/50). Remember that idle time of water leads frequent application for this purpose to gradual fluidifying of antifreeze and losing by mix of the of frost resistance and anticorrosive properties. It is also not necessary to abuse various type additives and additives.

3. Continuous falling of level of cooling liquid usually demonstrates development of leaks in system. Check for existence of traces of leaks a radiator, connecting hoses, a cover of a jellied mouth, drain traffic jams and the case water the pump (see the Section Check of a Condition of Components of the Cooling System). If it is not possible to reveal any signs of leaks, it is necessary to make check of a cover of a radiator pressure in the conditions of a workshop of car service.

Do not uncover a radiator / a broad tank at the hot engine at all!

4. In need of removal of a cover of a radiator wait for full cooling of the engine, then wind a mouth with a thick layer of rags and slowly turn off a cover to the first emphasis. If at the same time there is steam emission, let's the engine cool down a little more, only after it finally uncover.
5. Besides level always check also a condition of cooling liquid, - it has to be rather transparent. If cooling liquid is painted in henna-red color of a rust, the cooling system has to be emptied, washed out and filled with fresh mix of antifreeze with water. Even if liquid externally is not exposed to any changes, the corrosion inhibitors which are its part are exposed eventually to development therefore cooling liquid has to be replaced regularly according to the schedule of routine maintenance of the car (see the Section Schedule of Routine Maintenance of the Nissan Maxima Cars).
6. Try not to allow hits of antifreeze on open sites of skin or the painted surfaces of body components. Immediately wash away casual splashes a plentiful amount of water.


Liquid for washing of a windshield

 PERFORMANCE ORDER

1. Liquid for washing of a windshield is filled in in the special tank manufactured of plastic located in the right part of a motive compartment of the car in the neighbourhood with a broad tank of the cooling system.
2. In regions with a temperate climate as liquid for washing of glass clear water can be used, however it is not necessary to fill the tank more than on 2/3 for the purpose of compensation of expansion of water at its freezing during frosts. At operation of the car in severe climatic conditions it is necessary to fill in only patent screen wipers providing the corresponding decrease in a freezing point of liquid in the tank.

Rules of configuration of mix are usually printed on the label pasted on a container. Do not apply to addition in liquid of washing of glasses the antifreeze used in the cooling system at all, - the last is aggressive in relation to a paint and varnish covering of body panels!

3. In order to avoid frosting of glass when washing in cold weather previously warm up it by an obduv the air passed via the heater heat exchanger.


Electrolyte of the rechargeable battery

 PERFORMANCE ORDER

The cars considered in the present manual are completed with the battery of tight type which is not needing service in which case only air vents are provided. If in use the vehicle the battery for any reason was replaced with usual (served), it is necessary to check electrolyte level in its banks from time to time for what it is necessary to remove the top control/jellied traffic jams. Especially attentively it is necessary to watch electrolyte level in warm season. For adjustment of level of electrolyte it is necessary to use only the distilled water.


Hydraulic liquid of the brake system and drive of coupling

 PERFORMANCE ORDER

1. The Main Brake Cylinder (MBC) is located in the left top corner of a motive compartment of the car and fixed on the block of the servo-driver of the vacuum amplifier of brakes. The hydraulic cylinder of coupling is used on models with RKPP and fastens in the neighbourhood with GTTs directly on a back partition of a motive compartment.
2. Liquid level in the tank is well looked through through translucent walls of the last and has to be supported between the marks MIN and MOVE. Pay attention that the hydraulic path of the drive of coupling has a tight design and, in usual conditions, does not need adjustment of level of liquid (see the Head Stsepleniye and power shafts).

3. In case of need adjustments of level of liquid carefully wipe a cover of the corresponding tank and a surface around it with pure rags in order to avoid hit in hydraulic system of dirt.
4. At a liquid flood in the tank you watch that it was not sprayed on the surrounding painted surfaces of body elements. Add to each of systems only liquid of the grade stipulated by standard requirements (see Specifications at the beginning of this Chapter), - mixing of two liquids of various grade is inadmissible by no means and can lead to refusal of the corresponding system!

 Brake fluid is extremely chemically aggressive, - do not allow hit it in eyes and on the painted surfaces of body panels! Do not use for addition in system the hydraulic liquid which staid more than one year, or stored in leaky closed container. Remember that brake fluid is very hygroscopic, i.e. has ability to absorb moisture from air therefore efficiency of functioning of the brake system can dangerously decrease!

5. At a stage of adjustment of level it is necessary to check also attentively a condition of liquid and internal walls of the tank. In case of identification of mud deposits, firm foreign particles or drops of water the system has to be emptied and filled with fresh hydraulic liquid (see the Head the Brake system).
6. After the tank is filled to the required level, densely put on it a cover.
7. Remember that the level of hydraulic liquid in the GTTs tank in process of operation of frictional overlays of brake shoes gradually falls, however this decrease is always very insignificant. If liquid has to be added too often, therefore, in system leak which source has to be immediately revealed takes place, and the cause is removed, - attentively examine all brake lines and their nipple connections, including supports, wheel cylinders and the servo-driver of the vacuum amplifier (for more details see in the Section Check of the Brake System).
8. If during check of level of liquid in GTTs the fact that its tank is almost devastated is elicited, the brake system has to be pumped completely over (see the Head the Brake system).
