Can you service your hybrid electric vehicles air conditioning system the conventional way?




NO!

Newer hybrid and electric vehicles have moved to using high voltage system to power the electric compressor while conventional system are still belt driven by using the engine power.

It is important to know that the type of Air con compressor oil used in the system. Conventional A/C systems typically use PAG oil and hybrid & electric vehicles require polyester (POE) type oil. These oils have high dielectric properties, that are designed to lubricate the electric compressor whilst protecting its electrical windings.

Just as little as one percent of PAG oil in a hybrid system can affect the dielectric properties, reducing the insulation and causing damage to your compressor.


It is dangerous that it might introduce high voltage to the compressor housing and connected components, causing harmful and potentially lethal shock to service personal or anyone coming into contact with it.


Every hybrid or electric vehicle owner has to ensure that a separate recharging machine and the correct type of oil to be used on their car. A recharging station used for conventional A/C systems in conventional vehicles should not be used on hybrid & electric vehicles. This is because the residual PAG oil may still be present which would inadvertently be introduced into your hybrid vehicle during repair or recovery recharging.


Vehicle manufacturers recommend that all system components are to be replaced if cross-contamination of the oil has occurred in a hybrid or electric vehicle. This may potentially result in very costly repairs.
