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

Central air

Air central air constantly is under a high pressure. At all do not disconnect refrigerator lines and do not remove any components of system, previously without having executed a discharge of the last. The discharge of central air of air should be made by strengths of the skilled expert in the conditions of a car-care center workshop. At a rassoyedineniye of refrigerator lines surely put on goggles!

At replacement of components of central air of air the certain amount of replaceable refrigerator oil necessary for filling of volume of new knot is required. Use only the oil good for the use in R-134a systems (attentively study a label on the container).


The control checks listed below should be made on a regular basis for the purpose of maintenance of central air of air in good repair:

   a) Check a condition of a belt of a drive of the compressor. In case of detection of defects or signs of wear make replacement (see. Head Routine maintenance);
   b) Check effort of a tension of a driving belt, in case of need make the corresponding adjustment (see. Head Routine maintenance);
   c) Check hoses of a refrigerator path on existence of cracks, swellings, signs of hardening and rubber aging. In case of need make replacement;
   d) Check condenser plates on existence of the remains which have got stuck between them of insects, old leaves and other garbage. In case of need clean gaps a thin brush, or blow them the compressed air;
   e) Check level of a charge of system;

   f) At detection потеков waters on rugs in salon under the dashboard remove a drainage tube of removal of condensate from an evaporator casing (it is located in the bottom forward corner) and a piece of a wire check passableness of both openings (see an accompanying illustration).

Central air of air should join at least for 10 minutes not less often than once a month (even in a winter season). Long inaction To/in leads to hardening and failure of sealing rings and cuffs of a connecting path.

At inclusion of function of removal of products of an icing the К/В compressor will be involved.

In case of violations in work To/in, first of all check serviceability of functioning of the coupling of coupling of the compressor (see. Check of an electric chain of the coupling of coupling of the To/in compressor).

In view of complexity of a design of system and need of use of the special equipment, its service, deep diagnostics and regenerative repair lie outside the limits of qualification of the average amateur mechanic and should be made in the conditions of a car-care center workshop. The elementary checks only listed below in the real Management get to competence of the owner of the car and replacements.

The most typical cause of infringement of serviceability of functioning To/in is decrease in level of a charge of refrigerator oil. The elementary checks given below will allow to reveal signs of decrease in level of a coolant quickly.



1. Warm up the engine to normal working temperature.
2. Include To/in on the maximum hladoproizvoditelnost. Choose the maximum high-speed mode of the fan. Open doors to exclude the closed air circulation in salon.

3. Enter the thermometer into a target air line via the central deflector on the dashboard (see an accompanying illustration). At included To/in temperature of air leaving the deflector should lie in limits 2°С÷8°С. In very hot weather (40°С), increase of target temperature to 15°С, but is admissible no more.

4. If the requirements listed in the previous paragraph are not carried out, the system means needs a charging. For more detailed diagnostics of a condition of system the car should be driven away in a specialized workshop.

Coolant addition

For a charging of central air of air of cars considered in the real Management it is necessary to use only refrigerator R-134a oil.


1. Prepare standard charging set R-134a (ask in shops of automobile accessories). The structure of a set includes a ballonchik with refrigerator oil, a ventilny nozzle and the piece of a hose connected between the gate and the union of a low-pressure head part of a refrigerator path (see an accompanying illustration). As one ballonchik of oil it can appear insufficiently for a final charging of system, it is meaningful to buy on any cлучай at once pair. Track, that at least in one of ballonchik it was a little tinted in red color that will allow to reveal quickly leakages of a coolant in case of those.

At all do not fill in system more than two ballonchik of a coolant!

2. According to instructions of manufacturers connect a charging set to system. The design of shtutserny connections allows to make set connection only to a low-pressure head part of system.

At all do not make attempts of connection of a set to the union of a high-pressure head part of a path!

3. Close the gate on a transitional nozzle and screw the last on a ballonchik head, previously having made sure available a sealing ring / rubber laying.

Surely put on goggles!

4. Remove a dustproof cap from the union of a low-pressure head part of a refrigerator path and connect to it equipped with the socket of fast joining a hose of a charging set (see an accompanying illustration).

5. Warm up the engine and include К/В. Track, that the hose of a charging set did not adjoin to blades of fans of systems of cooling of engine/air conditioning.

The charging of system should be made at the working compressor. If the coupling of coupling of the compressor is disconnected, the system should be switched to the maximum hladoproizvoditelnost and to open all doors of salon.

That the compressor was not disconnected in the course of a charging, disconnect the socket from the low-pressure head switch (on some models the combined switch of a low/high pressure is used) and перемкните its paper clip or a wire piece.

6. Rotation of a ventilny nozzle pierce a ballonchik head, having opened thereby coolant giving (the characteristic sound of escaping gas should be heard). In the course of all charging discipline a ballonchik vertically, from time to time stirring up it. Between two series to a charging do a pause necessary for stabilization of system.
7. In the presence of near at hand exact thermometer enter it in via the deflector into the central air line To/in and watch on it temperature of air submitted to salon (see the paragraph 3 "Checks").
8. When the ballonchik will become empty, block the gate and disconnect a hose from the low-pressure head union of system. At once put on the union a dustproof cap.
9. Disconnect from a ballonchik a ventilny nozzle, in case of need rearrange it on the second ballonchik and continue filling. On termination of procedure put an unfinished ballonchik vertically on a rack and as required use it for system additional charge.

Heating system


1. Carpet moistening on a floor under the heater heat exchanger, or a steam-out via deflectors of air lines tell about leakages of the heat exchanger of a heater. Remove the heat exchanger (see. Replacement of the heat exchanger of a heater) also replace it new (the heater heat exchanger is not subject to regenerative repair).
2. If the heater does not provide heating of air submitted to salon, one of the following can be the reason of such refusal:
   a) The thermostat is jammed in open situation that allows submitted to heat up to the heat exchanger of a heater of cooling liquid of the engine to due temperature;
   b) Violation of passableness of an okhladitelny path that blocks supply of cooling liquid in the heater heat exchanger takes place. Feel the hoses connected to branch pipes on a back partition of an impellent compartment – both of them should be hot, otherwise passableness of a path is broken (hoses, the heat exchanger, or the operating valve of a heater) are blocked. Disconnect hoses and make obratnopotochny the heat exchanger. Previously having disconnected, wash out also both hoses.
   c) If to restore passableness of the heat exchanger by washing it is not possible, it is necessary to make block replacement.
