Removal and installation of the condenser of central air of air

These models of cars are equipped with safety cushions. The pillow constantly is in readiness and can work to (be inflated) at any time at the connected battery. In order to avoid casual operation of system (and receiving as a result of a trauma) each time at work with safety cushion components (including sensors of blow which can be located near a lattice/bumper lobby) disconnect from the battery a negative wire. After battery shutdown before starting to work it is necessary to wait not less than 2 minutes (the system is equipped with the condenser of a delay which should be discharged completely). For more details see. Head System of onboard electric equipment.


Air central air constantly is under pressure. Do not weaken shtutserny connections of lines and do not disconnect systems any of components before carrying out its discharge. The coolant should be extorted from system in special compensatory and regenerative ERA-blok at station of dealer office or in a specialized workshop of car-care center. At a rassoyedineniye of lines of system surely put on goggles!


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


 PERFORMANCE ORDER

  1. Make a discharge of central air of air (see the prevention above).
  2. Disconnect a negative wire from the battery.
  3. Remove a front grille (Head the Body).
  4. Remove a radiator (The section Removal and installation of a radiator and a broad tank of system of cooling).
  5. Disconnect refrigerator lines from the condenser, having released for this purpose metal clips of spring shtutserny connections. Smooth out connections, then, having fixed on them the special tool for disconnection of spring locks, twist tubes since both ends of connection, otstykovyvy them from each other.
  1. For removal of the condenser it is necessary расстыковать the shtutserny connections equipped with the spring lock - before remove metal clips (shooters).
  1. Having established the tool for undocking of spring locks before trying to disunite line tubes, twist them from each other.
  1. Give fixing bolts of arms of the condenser.
  1. Access to bolts of fastening of the condenser is possible through an aperture under front grille installation.
  1. Remove the condenser from the car and закупорьте the open ends of lines in order to avoid hit in moisture and dirt system.
  2. If the old condenser is established, store it unions up in order to avoid an oil effluence.
  3. In case of need condenser replacements, fill in in the new block of one ounce (28.35 g) coolant (R-134a type).

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

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