Refrigerant Line With RESTRICTOR
This illustration shows a refrigerant line -A- with a permanently installed restrictor -B- (without screen)
To remove the refrigerant line, remove the High-Voltage Battery Heater Core Refrigerant Shut-Off Valve -N542- (refer to High-Voltage Battery Heater Core Refrigerant Shut-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 restrictor hole -B- is approximately 0.7 mm. Depending on the version of the refrigerant line, this constriction is either permanently installed in the refrigerant line or is only inserted. A screen to separate floating deposits may be installed on the inserted version, which can block the restrictor hole.
Before installing check the bore -B- for debris and if necessary clean or replace.
There are different versions. Refer to the Parts Information.
