Keep the power steering system fed and sealed with the Dorman - OE Solutions Power Steering Reservoir 603-685. It drops in as a direct-fit replacement for the 1996-2000 Honda Civic, giving the hydraulic fluid that supplies the power steering pump a clean, leak-free container to replace one that has aged and cracked.

  • Holds the power steering fluid: stores and supplies fluid to the pump so the hydraulic system stays properly fed.
  • Direct-fit replacement: designed for the listed Honda Civic application to swap in for the worn original.
  • Addresses a common failure: reservoirs grow brittle and crack over years of heat and pressure, letting fluid seep out.
  • Fresh, sealed container: replaces the old reservoir so the system holds its fluid without the leaks and contamination that build up with age.

If a cracked or leaking reservoir is the cause of low fluid, a whining pump, or stiff steering, this part replaces the worn container; diagnose the source of any leak before installing.
