Volkswagen Golf Service & Repair Manual: Pressures and temperatures in the refrigerant circuit
WARNING
| When working on the refrigerant circuit, observe
generally applicable safety rules and the Regulations
for Pressure Tanks. |
|
| The pressures and temperatures in the refrigerant circuit
depend on the momentary operating conditions (e.g. engine speed,
speed 1, 2, or 3 of radiator fan, engine temperature, whether
air conditioner compressor is on or off) as well as
environmental influences (e.g. ambient temperature, humidity,
required cooling output). |
| In vehicles with air conditioner compressor regulating valve
-N280-, the pressure on the low-pressure side is varied by
activating the valve. |
| Therefore, the values given in the following tables may only
be considered as guidelines. They occur at an engine speed of
1,500 to 2,000 rpm and an ambient temperature of 20°C after
about 20 minutes. |
| The locations of connections provided for pressure
measurements can be found in the vehicle-specific coolant
circuits. |
| At 20°C and with the engine stopped, the refrigerant circuit
will adjust itself to a pressure of 4.7 bar positive pressure
→ Chapter. |

Engine oil consumption
First read and observe the introductory information
and safety warnings Engine oil consumption can vary from engine to engine
and can change during the working life of an engine.
Depending on how you drive and the conditions in which the car is used, oil consumption
can be up to 1.0 litre/ ...

Reinforced and Extra Load (XL) tyres
Some tyre manufacturers have for some time replaced the
designation “Reinforced” with the designation “Extra Load”. This
designation has long been standard in non-European countries.
Technically, there is no difference between them.
