Four Seasons offers suggestions on working on Taurus, Sable liquid lines, orifice tubes

Four Seasons recently released guidelines to assist in changing the orifice tubes on 2000 to 2007 Ford Taurus and 2000 to 2005 Mercury Sable vehicles.

At first glance, the liquid line looks like one long hose. But, unlike the liquid lines of the 1980s and 1990s, 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 eight inches 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 (No. 24608) and torque the fitting to 18 foot pounds.

“At Four Seasons, we not only deliver superior quality temperature control products, but we also make sure that professional technicians have access to the latest tech tips and top-notch training opportunities to allow them to get the job done right, the first time,” says Benny Araujo, Four Seasons marketing manager.
