Repair and operation of the car

Check of usefulness of functioning and service of systems of heating and air conditioning

System of air conditioning

The system of air conditioning constantly is below the high pressure. Not desconecte refrigerator lines in absolute and do not withdraw component any of the system, previously without having carried out an unloading of the last one. The unloading of the system of air conditioning has to be done by force of the expert tried in the conditions of a workshop of the service of the car. In a rassoyedineniye of lines of refrigerator certainly they put wide eyes! Substituting component of the system of rising certain air conditioning of oil of replaceable refrigerator necessary to be filled of the volume of the new knot it is going to be needed. Only use the good of oil for the use in the systems R-134a (attentively they study the etiquette in a container).

Service

The enumerated ones below of control checks have to become in a regular base for aims of the maintenance of the system of air conditioning in the good repair:

   a) Check a condition of a belt of the walk of the compressor. In case of detection of defects or signs of the use they do the substitution (to see the Front Regular maintenance);
   b) Check that the effort of a tension of a belt of driving, in case of the necessity they do the corresponding agreement (to see the Front Regular maintenance);
   c) Check hoses of a way of refrigerator of the existence of slits, swellings, signs of hardening and aging of rubber. In case of the necessity they do the substitution;
   d) Check plates of condenser to existence of remaining of insects, old leaves and another garbage that stuck between them. In case of the necessity a fine brush they clean slits or take compressed air to us;
   e) Level of load of system of control;

f) In the moment of the detection of potek of water in carpets in the hall below the panel they catch the telephone of drainage of the removal of condensed of a covering of evaporador (advanced corner is located in the bottom) and a part of a check of wire passability of both openings (companion sees an illustration).

The system of air conditioning has to be lit at least during 10 minutes at least once for month (even in the winter station). The long inactivity to / in group to hardening and failure of sealing rings and fists of sleeve of a way that is joined.

In the moment of the inclusion of the function of the removal of products to freeze the compressor К/В one teases.

In case of violations in the work to / in, first of all check the usefulness of the functioning of an union of pressure of the compressor (to see the Check of an electric chain of an union of pressure of the compressor K/V).

In view of the complexity of a drawing of the system and the necessity of the use of the special equipment, his service, the diagnostic deep one and the repair of recuperation are on the outside of the qualification of the middle amateur mechanic and have to be done in the conditions of a workshop of the service of the car. Only the elementary checks and the substitutions that are enumerated down in the present manual come to the competence of an owner of the car.

To lessen in the level of a load of oil of refrigerator is the most typical cause of the breach of the usefulness of the functioning. The elementary checks given down will allow to reveal signs of the reduction in the level of the refrigerant liquid quickly.

To check

ORDER OF REALIZATION

1. Heat the motor up to the temperature of normal work. 2. Include in in the very refrigeration capacity. Choose the very way of high speed of the supporter. Doors opened to exclude the air circulation closed in the hall. 3. Between in the thermometer in an air production tube he was seeing the central deflector in the panel (companion saw an illustration). In the included one in the Temperature of the air that goes out from the deflector it will be inside 2 °C÷8 of °C. In the very hot time (40 °C), I increase in the production temperature to 15 °C, but it is admissible not more. 4. If the demands enumerated in the prior paragraph are not carried out, the load of necessities of ways of system. For the most detailed diagnostic one of a condition of the system the car must be expelled in a specialized workshop.

Addition of refrigerant liquid

To collect of the system of air conditioning of the cars considered in the present manual it is necessary only to use the refrigerator oil of R-134a.

ORDER OF REALIZATION

1. There is prepared the standard that collects play of R-134a (ask in shops of motor accessories). The mouth of valve and the part of a hose joined between the door and the union of a part of low pressure of the road of refrigerator are a part of the play a barrel with the oil of refrigerator (companion sees an illustration). Since an oil barrel can appear insuficientemente for the load of end of the system, does sense to buy in any couple of if at the same time. The trace that at least in one of barreis was tinged a little in the red color that there will allow to reveal quickly the hole of the refrigerant liquid in if of that. Do not fill any more than two bar of the refrigerant liquid in the system in absolute! 2. According to the manufacturers' educations they join the porter to the system. The drawing of connections of nipple allows to do the connection of the play alone to a part of low pressure of the system. Do not do attempts of the connection of the play to the union of a part of high pressure of the road in absolute! 3. Close the door in a transitional mouth and screw the last thing in a head of barrel, previously when there secured available a ring of fighter / placing of rubber. Certainly put wide eyes! 4. Withdraw a hat on trial of powder of the union of a part of low pressure of the road of refrigerator and it joins the hose of the equipped porter of the capture of bystry what is joined (companion sees an illustration). 5. Heat the motor and include К/В. The trace on which the hose of the porter did not border to supporters' systems blades is cooled by them of the motor / air conditioning. The load of the system has to be done in the work compressor. If the union of pressure of the compressor desconectar, it is necessary to exchange the system to the very refrigeration capacity and to open all the doors of the hall. That the compressor was not disconnected in the course of the load, desconecte the capture of the low switch of pressure (in any models the combined switch of a high pressure / decrease is in use) and you peremknit link a clip of paper or a part of a wire. 6. The rotation of a mouth of valve perforates a head of barrel, when opened through that the provision of refrigerant liquid (the characteristic sound of the gas that escapes has to be heard). In the course of your whole load they discipline a barrel vertically, from time to time lifting it. Between two series they do to the load of the pause necessary for the stabilization of the system. 7. In the presence of near to the right thermometer to the hand they enter in him in road the deflector in the central air tube to / in and it looks in him at the temperature of the air given to the hall (to see the paragraph 3 "Checks"). 8. When the barrel is I discharge, blockade the door and desconecte a hose of the union of low pressure of system. At the same time put a hat to the test of powder to union. 9. Desconecte a mouth of valve of a barrel, in case of the necessity readjusts it in the second barrel and continues the petrol station. In the end of the proceeding they put an unfinished barrel vertically in a torture and like needy use that for recarrega of the system.

Heating system

ORDER OF REALIZATION

1. The moistening of a fitted carpet in a floor below the conductor of heat of heater or steam had been a road deflectors of air tubes it calls itself leaks of the conductor of heat of a heater. Remove the conductor of heat (to see the Substitution of the conductor of heat of a heater) and substitutes it new (the conductor of heat of heater is not subject to the recuperation repair). 2. If the heater does not supply the heating of the air given to the hall, one of the next one can be the reason of such a refusal:    a) O thermostat corsets itself in the open situation that allows fact to a conductor of heat of a heater of cooling the liquid of the motor to be heated up to the proper temperature;    b) A violation of passability of a way that cools happens what blockades the provision of cooling the liquid in the conductor of heat of heater. Feel the hoses joined tubes of branch in a rear splitting of a compartment of reason – both will be hot, otherwise passability of a way one breaks (hoses, the conductor of heat, or the valve of operational heater is blockaded). Desconecte hoses and do obratnopotochny the conductor of heat. Previously having desconectado, wash that it had been also both hoses.    c) If it is not possible to restore passability of the heat conductor washing itself, it is necessary to do the substitution of the block.
