What does this power steering pump do?
It generates the hydraulic pressure that powers your steering assist, making the wheel easier to turn. When it fails, steering can feel heavy and the pump may whine.
Which vehicles does the 20-279 fit?
It's a direct-fit replacement for the 1997-2005 Ford Explorer, 2001-2003 Explorer Sport, 2001-2003 & 2005 Explorer Sport Trac, 2001-2011 Ranger, 2001-2009 Mazda B4000, and 1998-2005 Mercury Mountaineer. Check the Buyer's Guide.
What are the seals made of?
The pump is built with 100% new O-rings and premium-grade HNBR seals, which resist breaking down at high temperatures unlike conventional seal material, helping prevent leaks.
Is this pump tested before shipping?
Yes. Critical components like campacs and spool valves are triple-tested, pressure relief valves are calibrated, and final assembly is computer-tested for pressure, flow, valve operation, steering effort and noise.
How do I know if my power steering pump is failing?
Common signs include a whine or groan when turning, heavy or hard steering, and fluid leaks. Diagnose the cause first, since these symptoms can have other sources.
