Fig. 6.94. Installing the hydraulic unit
Caution! Point the tip of the hydraulic unit ground wire downwards to ensure the tightness of the hydraulic unit ECU connector (Fig. 6.94).
Install the air conditioner refrigeration circuit piping.
Tighten to the specified torque:
- hydraulic unit bracket mounting bolts (6.5 Nm);
- bolts for fastening pipelines on the hydraulic unit (14 Nm);
- intake manifold mounting bolts (9 Nm);
- bolts for fastening the hydraulic unit to the bracket (8 Nm).
Note: Replace the gasket each time the throttle body is removed.
Note: Be sure to replace the gaskets at the ends of the air conditioner refrigeration circuit pipe.
Bleed the brake system.
Connect the battery.
Re-initialize the programmed throttle end positions.
Charge the refrigeration circuit with refrigerant.
Check the functionality of the air conditioning system by running the electric fan at maximum speed.
If uncooled air is supplied to the cabin, look for a refrigerant leak.
Electric pump unit
Note: Cars are equipped with two types of electric pumps: for the ABS system, or for the ABS system combined with the trajectory stabilization system.
