Refrigerant

The refrigerant system requires refrigerant and oil in the quantities listed below:

Refrigerant-134a
Suburban with Front A/C only 1.02 kg (2.25 lb)
Suburban with Rear Air Conditioning 1.81 kg (4.0 lb)


Polyalkaline Glycol (PAG) Refrigerant Oil
With Front Air Conditioning System 240 ml (8 fl oz)

- Overcharging a system may allow liquid Refrigerant-134a to get into the compressor, causing compressor noise and damage. Undercharging will cause insufficient cooling.
