Refrigerant Circuit Connections With Valve For Switches

WARNING: This page is about a different car, the 2014 Volkswagen Touareg, 2013 Volkswagen Touareg, 2012 Volkswagen Touareg, and 2011 Volkswagen Touareg. However, it is still accessible from the selected car via links, so may be relevant.

NOTE:

For switching pressures, removing and installing switches and switch arrangement and version, see vehicle-specific refrigerant circuit.

Refer to the appropriate service information .

CAUTION:

Danger or frostbite due to refrigerant coming out under pressure.

Frostbite on the skin and other parts of the body is possible.

- Wear safety gloves.

- Wear protective eyewear.

- Extract refrigerant and open the refrigerant circuit immediately.

- If more than 10 minutes elapse after extracting the refrigerant and the refrigerant circuit was not opened, extract the refrigerant again. Evaporation can cause pressure to develop in the refrigerant circuit.

Different threads for switch on high pressure and low pressure sides.
Only valves and O-rings that are resistant to refrigerant R134a and the associated refrigerant oil may be used.
