How to fix air conditioning in the car

Air conditioning in the car - no longer a luxury. Most modern machines come from the conveyor with installed air conditioning systems. Usually, the level of freon is checked at that. However, if you have a suspicion that it's time to fix air conditioning, without prior diagnosis, in any case, do not do ...

Annual Natural Loss of Freon - about 15%. This means that once every 3 years air conditioning in a car should be charged.

Significant cooling gas losses may indicate the leaks of the pipeline connections or corrosion in the condenser. It should be remembered that when refrigerant leakage, first of all, it is necessary to eliminate the causes of losses and only after that refueling the air conditioner.

Currently, Freon R-134a is used to refuel air conditioners. It is less effective than the one that was used until the mid-90s (R-12), but more sparing for the ozone layer. If the year of release your car before the 92nd, then the R-12 is needed. For confidence, check the inscription on a special sticker from the inside of the hood, it will be indicated there, on which gas is your air conditioning.

Before filling the air conditioner, you need to clarify how much freon gas will be required. Typically, this information is indicated on the same table where the type of gas used is marked. If the data is absent, the norm can be found at the representative of the car brand. For example, air conditioners in domestic machines are used on average 750-1000 grams of refrigerant.

Cleaning the air conditioning system is also an important stage when refilling the cooling device. To do this, purchase a special cleaning foam and fill out the cavity of the radiators and the air conditioner heater.

To actually refueling the air conditioner, you will need to purchase a metrological station, a phonon cylinder, hoses and an adapter with a crane. However, there are ready-made sets for self-containers for self-containers. In the top of the cylinder with a refrigerant, there is a thread and a place to connect an adapter using a needle. Screw the adapter to the cylinder and attach one end of the hose. Connect the other end of the hose to the metrological station, the second hose is also connected to it.

Fail the pressure meter is necessary before screwing to the cylinder with freon adapter. Wheel Place the ambient temperature.

The auto air conditioning has low and high pressure asses. Filling the device is necessary on the low pressure side.

Remove the cap from low pressure holes, first clearing the entrance from contamination. At the filling station, attach the hose.

Start the engine, raising the turnover to 1500. Turn on the air conditioner to the maximum. Open the low pressure valve and open the crannel of the cylinder with the refrigerant. Air conditioning will be refundable when the motor is running.

When refueling the air conditioner, follow the pressure meter. The arrow should be on a not higher than 285 kPa.

After some time, cold air will start to the salon. Wait for the temperature when the temperature reaches 5-7 degrees Celsius, after which you close the cylinder crane.

In the filter-desiccant window, a homogeneous transparent liquid without air bubbles should be visible. This means that the system is completed correctly and your work is completed. You can disconnect the refueling system.
