To remove the refrigerant line, remove the High Voltage Battery Heater Core Refrigerant Cut-Off Valve -N542- (refer to HIGH VOLTAGE BATTERY HEATER CORE REFRIGERANT CUT-OFF VALVE -N542-, REMOVING AND INSTALLING ) and remove the refrigerant line from the High Voltage Battery Heat Exchanger. Refer to HIGH VOLTAGE BATTERY HEAT EXCHANGER, REMOVING AND INSTALLING .

The diameter of the illustrated variable orifice -B- is approximately 0.7 mm. Depending on the version of the refrigerant line this constriction is either installed fixed in the refrigerant line or only inserted. For the inserted version a strainer for flowing deposits may be installed, which can be blocked by the variable orifice.

Before installing check the bore -B- for debris and if necessary clean or replace.
