Not exactly sure but using info below you can find it.

Remember the flow for the a/c system is :
1. From the compressor a high pressure (HP) gas goes to the condenser in front of the radiator.
2. From the condenser a HP liquid goes to an expansion device (orifice tube or expansion valve)
3. From expansion device the low pressure gas enters the firewall to the evaporator.
4. From evaporator the low pressure liquid/gas mixture goes through the dryerwhere is the orifice tube on a 98 Buick LeSabre - 2_bing.gif back to the compressor suction.

There will be about a 1" nut on the low pressure line between the firewall and the compressor. Remove nut and on the male side use a pair of kneedle nose pliers and remove orifice tube. Note orientation of tube.

Replace tube, reassemble, evacuate air from system, recharge with freon.

On the a/c system...if you have to ask, take it to the shop. This is not a backyard mechanic job.

Replaced ac compressor for 1992 Buick LeSabre but cannont figure out where orifice tube goes. Auto supply stroe said it attaches to dryer but I don't see where.


Its usually in the high side tube you have to look for some small knurl marks that hold the orfice in place,its always where a hose connects so you can get to it but be careful cause they can be hard to get out if its stuck but they make special tools to reomve them if its stuck,use good needle nose plyers.let me know if you need more info have a good day DB
