Volkswagen Golf Service & Repair Manual: O-ring
| These O-rings seal the joints between the individual
components of the refrigerant circuit. |
| Use only seals that are resistant to refrigerant R134a and
its associated refrigerant oils. This is assured by using
genuine replacement parts. |
| Check that diameters -a- and
-b- are correct. |
| Before fitting a seal, coat it lightly with refrigerant oil. |
 Note
| The colour coding of O-rings for R134a refrigerant circuits
has been discontinued. Coloured and black O-rings are used. |

The expansion valve atomises incoming refrigerant and
regulates the flow so that, depending on the heat transport, the
vapour does not become a gas until it reaches t ...

Note
Fuel tank leak detection takes advantage of the fact that a
vacuum develops naturally in the fuel system as the fuel in the
tank cools. The variables temperature and pressure are necessary
for fuel tank leak detection. The temperature senso ...
Safety precautions when working in the vicinity of high-voltage components
Danger to life due to high voltage
The high-voltage system is under high voltage. If high-voltage
components are damaged, there is a risk of severe or fatal injury due to
electric shock.
