    AC Help - Fiero with V5 134a compressor and OBD1 computer

    OK Guys I need a little help.

    I am using a V5 compressor on a stock Fiero AC system. I went to the bone yard and picked up the correct hose end for the compressor. I also have the stock hose from the original system. I am planning to bring them to a shop next week to have a custom hose made to adapt the new compressor.

    I will also have an inline fitting installed for a switch to be used on the high side and bypass the low side switch on the dryer to work properly with the ECM. The motor was converted to a 3.4L DOHC and is using a 92 OBD1 computer which controls the system. Does this configuration sound correct?

    Also, what can I use to clean out the system? The car had been sitting for a long time and Im sure the system needs to be flushed out. I will also be replacing the dryer and orifice tube. I read someplace that the orifice tube should be replaced with one for R134a VS the stock one that was designed for R12. Can anyone shed some light on this?
