Year: 1995
Make: Chevrolet
Model: Impala SS
Engine Size: 5.7
Refrigerant Type: 134a
Pressure Low: Empty
Pressure High: Empty
Country of Origin: United States

The orifice valve is basically part of the condenser on the out line in my 95 Impala SS. Where am I suppose to put an inline filter if it is suppose to be between the condenser and orifice valve? Is there another location I can put it? Has anyone else had this problem on a Chevy?

I don't use them...

-------------------------
The number one A/C diagnostic tool there is- is to know how much refrigerant is in the system- this can only be done by recovering and weighing the refrigerant!!
Just a thought.... 65% of A/C failures in my 3200 car diagnostic database (GM vehicles) are due to loss of refrigerant due to a leak......

There's no need for an aftermarket liquid line drier. Do you not have a suction filter of any kind between the evaporator and compressor?

There is no knowledge that is not power

The filter is designed to go in the liquid line between the condenser and the orifice. In this case you do not have that line to tap into.
