Power Steering Flush for Work Vans

Delivery and service drivers turn the wheel more in a day than most drivers do in a week. Parallel parking at a curb in Midtown, backing into a loading dock in Sparks, three-point turns in a cul-de-sac in Damonte Ranch. On a van with hydraulic steering, every one of those maneuvers works the pump near full pressure.

Which vans have fluid to service

Mixed fleets often include both systems. Long-running van platforms like the Chevrolet Express and GMC Savana use a belt-driven hydraulic pump. Many newer vans use electric power steering with no fluid. The owner's manual and the presence of a power steering reservoir tell us which, and we do not quote a flush on a van that cannot use one. Mercedes-Benz lists approved hydraulic fluids by sheet number on its operating fluids site for Sprinter models that need them.

• Each van's steering type noted on its first visit
• Fluid level and condition checked on hydraulic vans at every oil change
• Flush with the specified fluid when worn, quoted to your approver first
• Leaks or belt wear noted for your repair vendor
• Unit number and mileage on every invoice

Why vans wear steering fluid faster

Holding the wheel at full lock pushes a hydraulic pump to its relief pressure, which turns energy into heat in the fluid. A van that does that dozens of times a day, then idles at a job site, cooks its fluid faster than the mileage suggests. Ford's scheduled maintenance guide treats idling and heavy use as special operating conditions, and the Car Care Council's guidance is to check level and condition regularly and change dark fluid. Summer heat adds to it; the Reno airport averages about 65 days a year at 90 F or hotter (NOAA 1991-2020 normals).

How fleet visits work

1. Drivers bring vans to whichever of the four service centers is on the route, no appointment needed.
2. We check the steering type and fluid along with the oil change.
3. Anything beyond the oil change is quoted to the person you name.
4. Fleet accounts get detailed records by vehicle and priority scheduling through the fleet program.

Signs a driver should report

A whine at full lock, a heavy wheel on cold mornings, or a reservoir that keeps needing fluid are worth a call to the office. The fix may be fresh fluid, or it may be a pump or hose for your repair vendor, and we will say which. Send the van in today rather than after the route goes wrong.
