Keep your power steering fluid sealed in and road grime out with the Dorman - HELP Power Steering Reservoir Cap (P/N 82589). It installs as a direct-fit replacement for a long list of GM cars, including the 1989-2005 Buick Century, 1993-2002 Chevrolet Camaro, 2000-2005 Chevrolet Impala, 1997-2006 Chevrolet Malibu, 1999-2004 Oldsmobile Alero, 1994-2005 Pontiac Grand Am and 2001-2005 Pontiac Aztek. See the Buyer's Guide tab for the full list of 37 applications.

  • Seals the reservoir: closes off the power steering fluid reservoir to help retain fluid and keep dirt and moisture out of the system.
  • Direct replacement: a straightforward swap for a cap that is cracked, worn, warped, or missing.
  • Restores a proper seal: if a failed or lost cap is the cause of fluid seepage or contamination around the reservoir, this replaces it.

A power steering cap can dry out, crack, or lose its seal over time, so signs it may need replacing include fluid weeping from the reservoir top, a cap that no longer stays secure, or dirt collecting in the fluid. Always diagnose the source of any leak before replacing parts.
