Taurus/Sable Liquid Line and Orifice Tube


Four Seasons offers the following guidelines to assist in changing the orifice tubes on 2000-’07 Ford Taurus and 2000-’05 Mercury Sable vehicles.

At first glance, the liquid line looks like one long hose. But, unlike the liquid lines of the ’80s and ’90s, this hose has a fitting in the middle. The orifice tube is located at this fitting. Four Seasons’ part number for the orifice tube is 38639.

To replace the orifice tube:
1. Remove the washer and overflow bottle. The high side service port is on a pipe about 8” long to make it easier for service. The fitting and orifice tube are near this pipe. The fitting is covered with a protective rubber cover that makes it hard to see the fitting.
2. Push the cover back.
3. Disconnect the fitting.
4. Replace the orifice tube.
5. Lubricate the new O-ring (#24608) and torque the fitting to 18 lb.-ft.
