What is the minimum relief pressure for the 3.0L (2V) Taurus power steering pump?

The 3.0L (2V) engine with pump model HBC-LC has a minimum relief pressure of 8960 kPa (1300 psi).

What power steering pump is used on the 3.4L (4V) engine and what are its specs?

The 3.4L (4V) uses pump model ZUA: minimum flow 7.57 L/min (2.0 gal/min) at 5100 kPa (740 psi), minimum relief pressure 10135 kPa (1470 psi), maximum relief pressure 10963 kPa (1590 psi), and maximum free flow 8.7 L/min (2.3 gal/min) at 1500 rpm.

What is the pump part number for the 3.0L/3.2L SHO?

The 3.0L/3.2L SHO pump is listed as F3DC-3A674-BA, with 3.4 L/min minimum flow, 9650 kPa (1400 psi) minimum relief pressure, and 10550 kPa (1530 psi) maximum relief pressure.

What conditions must be met when checking pump minimum flow capacity?

Flow depends on pump model, engine rpm, and pulley drive ratio, and the engine idle rpm must be set to specification when checking pump minimum flow capacity.

What is the maximum free flow at 1500 rpm for the 3.0L and 3.8L Police engines?

9.8 L/min (2.6 gal/min) with pump model HBC-RE.

This document presents two power steering pump specification tables, apparently covering second- and third-generation Ford Taurus engines. The first table lists specifications for the 3.0L and 3.8L Police engines (pump model HBC-RE) and the 3.0L/3.2L SHO engines (pump part number F3DC-3A674-BA): both have a minimum flow of 3.4 L/min (0.9 gal/min) at 5100 kPa (740 psi) and 78°C (172°F), minimum relief pressure of 9650 kPa (1400 psi), maximum relief pressure of 10550 kPa (1530 psi), and maximum free flow of 9.8 L/min (2.6 gal/min) at 1500 rpm. The second table covers the 3.0L (2V) with pump HBC-LC and 3.0L (4V) with pump HBD-BM — both 3.4 L/min minimum flow, 8960 kPa (1300 psi) minimum relief, 10205 kPa (1480 psi) maximum relief, 9.8 L/min free flow — and the 3.4L (4V) with pump ZUA at 7.57 L/min (2.0 gal/min) minimum flow, 10135 kPa (1470 psi) minimum relief, 10963 kPa (1590 psi) maximum relief, and 8.7 L/min (2.3 gal/min) free flow. Footnotes on both tables stress that flow depends on pump model, engine rpm, and pulley drive ratio, and that idle rpm must be set to specification when testing minimum flow.
