Mobile car aircon regas Perth services from CMM Automotive help drivers restore their vehicle’s cooling system. Recently, we attended a Toyota Prado in Joondalup with a broken rear air conditioning hose. The high-pressure hose had failed, causing a fault in the rear cooling system.
Our mobile mechanic replaced the broken hose and regassed the air conditioning system. As a result, we completed the repair without the customer needing to visit a workshop.
Toyota Prado Rear Air Conditioning Problem in Joondalup
The Toyota Prado has a large cabin, making effective air conditioning important during Perth’s hot summers.
Many Prado models have rear air conditioning to help cool passengers in the back seats. These systems use refrigerant lines that run from the front of the vehicle to the rear cooling unit.
However, these longer lines can develop faults over time.
In this case, the Prado had a broken high-pressure hose leading to the rear air conditioning unit.
A damaged hose can allow refrigerant to escape. As a result, the system may lose cooling power or stop working.
Our mobile mechanic attended the vehicle in Joondalup to repair the fault.
What Causes Rear Air Conditioning Hoses to Fail?
Rear air conditioning hoses and pipes face heat, road dirt and vibration during normal driving.
Over time, these conditions can cause wear or damage.
Common causes of rear A/C hose failure include:
- Age and general wear.
- Damage from road debris.
- Cracks in rubber hose sections.
- Corrosion around metal fittings.
- Vibration from normal driving.
- Damage caused by rubbing against nearby parts.
In addition, poor hose support can place extra strain on joints and fittings.
Even a small leak can reduce cooling performance.
Therefore, finding and fixing the leak is important before adding more refrigerant.
Why a Car Aircon Regas Alone Will Not Fix a Broken Hose
Some drivers believe that adding refrigerant will fix an air conditioning system that no longer blows cold air.
However, a regas cannot repair a broken hose.
If the system has a leak, new refrigerant may escape again. This wastes money and leaves the original fault unresolved.
For this reason, we always aim to find the cause of poor cooling before carrying out a regas.
A car air conditioning service Perth inspection can help locate leaks, damaged hoses and other faults.
Once a technician fixes the leak, they can prepare the system for recharging.
Replacing the Toyota Prado Rear High-Pressure A/C Hose
After finding the broken rear high-pressure hose, CMM Automotive replaced the faulty part.
The hose carries refrigerant to the rear air conditioning unit. Therefore, it must remain sealed during normal system use.
A damaged hose can prevent the system from holding the correct refrigerant charge.
Replacing the faulty hose allows the refrigerant circuit to operate as intended.
During this type of repair, technicians must also take care with the hose fittings and seals.
Correct fitting helps reduce the risk of future leaks.
Once we completed the hose replacement, we could move on to the air conditioning service.
Mobile Car Aircon Regas Perth – Recharging the Prado
After replacing the hose, we regassed the Toyota Prado’s air conditioning system.
A proper regas involves more than simply adding refrigerant.
First, the technician must ensure the system is ready for recharging. This may include pressure testing and checking for leaks.
Next, suitable service equipment removes air and moisture from the system.
Finally, the technician adds the correct refrigerant charge for the vehicle.
The correct amount is important because both low and high refrigerant levels can affect cooling.
CMM Automotive provides mobile car aircon regas Perth services for vehicles using R134a and R1234yf refrigerant.
We select the correct refrigerant and charge amount for each vehicle.
Signs Your Toyota Prado May Have an Air Conditioning Leak
Air conditioning leaks can develop slowly or appear after a part breaks.
Common warning signs include:
- Air from the vents no longer feels cold.
- The rear air conditioning stops cooling.
- Cooling performance becomes weaker.
- The system loses cooling soon after a regas.
- Oily marks appear around A/C hoses or fittings.
- The compressor cycles more often than normal.
However, these signs can also point to other air conditioning faults.
For example, poor cooling may result from an electrical problem or a faulty compressor.
Therefore, a proper inspection is the best way to find the cause.
Why Rear Car Air Conditioning Repairs Need Care
Rear air conditioning systems have extra hoses, pipes and fittings.
As a result, they have more areas where leaks may develop.
A rear car air conditioning repair Perth service may involve checking lines that run under the vehicle or along the body.
These areas can suffer damage from road dirt, vibration and age.
In addition, a leak in the rear circuit can affect the refrigerant charge for the whole system.
This means a rear hose fault may also reduce cooling at the front vents.
Fixing the damaged part is the first step towards restoring proper cooling.
