Dorman - OE Solutions Vacuum Pump P/N:904-861
Dorman 904-821 vacuum pump for the 2010-2017 Rolls-Royce Phantom and other vehicles creates vacuum for the car's vacuum-operated functions. It matches the original equipment pump in fit and function and is intended to restore operation of those functions.
A worn pump can show up as weak vacuum-operated functions or noise from the pump area. A leaking vacuum hose or loose connection can cause weak vacuum as well, so with the engine off and cool, look the pump and its hose over for cracks and loose fittings before you replace it.
This mechanical vacuum pump is a direct-fit replacement for the 2010-2017 Rolls-Royce Phantom, the 2006-2010 BMW 550i and the 2006-2010 BMW 650i, along with many other vehicles. If your car isn't named here, open the "Vehicles it fits" section and look up your exact model and year.
