Removal and installation of the condenser of the air conditioning system

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) every time during the work with safety cushion components (including blow sensors which can be located near a forward lattice / bumper) disconnect a negative wire from the battery. After shutdown of the battery before getting to work it is necessary to wait not less than 2 minutes (the system is equipped with the delay condenser which has to be discharged completely). For more details see the Head Sistem of onboard electric equipment.


The air conditioning system constantly is under pressure. Do not weaken nipple connections of lines and do not disconnect systems, any of components, before carrying out its discharge. Coolant has to be extorted from system in special compensatory and recovery ERA-blok at the station of dealer office or in a specialized workshop of car service. At a rassoyedineniye of lines of system surely put on goggles!


The accumulator (store) has to be replaced (The section Removal and installation of the accumulator (store) of the air conditioning system) every time when replacing the condenser.
