Citroen CX Air conditioning low-pressure hose replacement
Does your Citroen CX need a new air conditioning low-pressure hose?
The air conditioning (A/C) system in your Citroen CX involves a lot more than a button on the cabin centre console. Behind the scenes, the system comprises a compressor, condenser, evaporator, drier, relay, switches and refrigerant.
The system is essentially split into two sections - a high-pressure side and a low-pressure side and the refrigerant in your Citroen CX’s is transformed between a gas and liquid depending on whether it is under high or low pressure.
The refrigerant is circulated through the A/C system. It does this via tubes and hoses and as the refrigerant moves from the evaporator to the compressor in your Citroen CX it is under low-pressure, so the hose required is a low-pressure hose.
When refrigerant is returning through the low-pressure hose it is in a gaseous state.
The A/C low-pressure hose is made of metal and rubber and is located inside the engine bay. Due to heat, deterioration and age, the A/C low-pressure hose can develop holes and/or leaks.
When the A/C low-pressure hose develops a leak, this will render the A/C system useless. As soon as the A/C loses pressure, the system will not operate properly and it will stop providing cool air.
Signs the low-pressure hose may need replacing:
- There is no cold air circulation
- Audible noise of gas escaping from the engine bay
- Obvious damage to the hose
- A refrigerant leak around the hose
The A/C system is complex. Never attempt to carry out A/C repairs yourself. Always have a qualified air conditioning professional perform the repairs.
If you are aware of a leak, don’t continue to use your A/C. Keep it switched off and have it fixed as soon as possible. The system can’t operate effectively with leaks.
If you continue to use the A/C system with low refrigerant levels you will eventually damage other components within the system which can cost thousands to repair. It's much better to replace a hose now than a whole system later.
Any repairs on an A/C system requires the emptying of refrigerant and refilling again, this does add extra cost to the service which cannot be avoided.
Book an AutoGuru qualified A/C mechanic to replace your Citroen CX's low-pressure hose so you can succumb to that cool breeze once again.
