Removal and installation of the condenser of a central air of air

The given models of cars are equipped by safety pillows. The pillow constantly is in readiness and can work to (be inflated) at any moment at the connected battery. In order to avoid casual operation of system (and receptions as a result of a trauma) each time at work with components of a pillow of safety (including gauges of blow which can be located near to a forward lattice/bumper) disconnect from the battery a negative wire. After battery switching-off before starting to work it is necessary to wait not less than 2 minutes (the system is equipped by the condenser of a delay which should be discharged completely). The Head the System of an onboard electric equipment more in detail see.

Air central air constantly is under pressure. Do not weaken штуцерные connection of lines and do not disconnect systems any of components before carrying out of its discharge. The coolant should be extorted from system in the special compensatory-regenerative ERA-BLOCK at station of dealer branch or in a specialised workshop of car-care centre. At рассоединении system lines necessarily put on goggles!

The accumulator (store) should be replaced (Has undressed Removal and accumulator installation (the store) air central airs) each time at condenser replacement.


    Make a discharge of a central air of air (the prevention above see). Disconnect a negative wire from the battery. Remove a radiator lattice (the Head the Body). Remove a radiator (Has undressed Removal and installation of a radiator and a broad tank of system of cooling). Disconnect refrigerator lines from the condenser, having released for this purpose metal clips spring штуцерных connections. Smooth out connections, then, having fixed on them the special tool for disconnection of spring locks, twist tubes from both ends of connection, отстыковывая them from each other.
    For condenser removal it is necessary расстыковать штуцерные the connections equipped with the spring lock - before remove metal clips (arrows).
    Having established the tool for undocking of spring locks before to try to disunite line tubes, twist them from each other.
    Give fixing bolts of arms of the condenser.
    Access to bolts of fastening of the condenser is possible through an aperture under installation of a lattice of a radiator.
    Remove the condenser from the car and закупорьте the open ends of lines in order to avoid hit in moisture and dirt system. If the old condenser is established, store its unions upwards in avoidance вытекания oils. In case of need condenser replacements, fill in in the new block of one ounce (28.35) coolants (type R-134a).

In each of штуцерных the connections equipped with spring locks at installation the sealing rings suitable for use in systems, filled with oil of type R-134a should be put.

    Installation make upside-down. Do not forget to establish under the compressor rubber pillows. Correct packing of sealing strips round the condenser and a radiator make according to instructions Has undressed Removal and installation of a radiator and a broad tank of system of cooling. In the same workshop where made a discharge, empty, charge and check up system on leaks.
