Warning: Do not open the refrigerant circuit of the air conditioning system. Avoid skin contact with refrigerant.
The A/C compressor, together with the bracket, can be removed and installed without opening the refrigerant circuit. When carrying out repair work, the air conditioning compressor can be removed and hung in the engine compartment without disconnecting the hoses from it.
Chalk, marker or paint, mark the direction of rotation of the V-ribbed belt. If the V-ribbed belt rotates in the opposite direction during installation, this will lead to its destruction.
