You seem to be clinging to the belief that an orifice tube is part of a Saturn (GM) system when it does not exist at all. The GM equivalent filter is inside the receiver/accumulator/filter/drier assembly, a cannister. It is inline after the compressor and before the condenser on GM systems. Anyplace a filter is incorporated in any vehicle a/c system is for final filtering of any loose debris that may interfere with thecompressor valvesor clog thetubes of the evaporator core, condenser coils, hoses, and throttle expansion valve. Assuming you'rewriting about a/c systemson a Saturn site I am concluding that your general question requires a specific answer and to help illuminate your understanding of a very good question but not pertaining to Saturns and GMin general as an orifice tube is a component of Ford systems. Now, checking with ackits.net, I see that there is a production line addition of an inline filter that is a flattering complement to Ford being added to '03 GMmodels and up.I am guessing thatthis additional filter was incorporated due to recurring problems with a/c system repairs where more debris is circulating and possibly damaging the compressor. This is only a guess on my part as most GM systems work as designed as well as Ford systems. They just differ in where the parts are combined (GM) or separated (Ford).
