Comments about ToughOne Air Conditioning Accumulator:
My original had four ports. This one had only three. The fourth port was for the Freon pressure switch. With only three ports you have to bypass this switch to engage clutch. After charging remove adapter and re-install pressure switch on accumulator. If you ever have to add freon again you will have to remove this switch so you will have a low-side port to charge with.

Q:I have seen online where several GM products use the service port on the accumulator as the LOW PRESSURE charging port. On a 1989 Olds 88 is this the port that I can use to add R134a refrigerant after the car was converted to the new refrigerant? Thanks
A:The accumulator is mounted in the low side of the system, at the outlet of the evaporator. The function of the accumulator is to store (accumulate) refrigerant and to filter and dry the refrigerant. The accumulator also contains a desiccant. If any liquid refrigerant passes out of the evaporator the accumulator will store it. Liquid refrigerant is harmful to the compressor. Moisture is also harmful to the air conditioning system. It is compatible with either R12 or R 134a.
