Where is the orifice tube on a 1997 olds 88?

The orifice tube on a 1997 Oldsmobile 88 is typically located in the liquid line of the air conditioning system. To find it, trace the line from the condenser to the evaporator; the orifice tube is usually situated near the evaporator inlet. It may require some disassembly to access, as it is often housed within a fitting that connects the two lines. Always ensure the system is properly evacuated before attempting to replace the orifice tube.
