Cadillac DTS Forum - 2006 through 2012 Discussion, 2007 DTS - power steering noise in Past Cadillac Vehicle Discussion; Had upper power steering hose replaced now there is a constant roar from engine area not depending if I turn ...
Air can be a common problem in power steering systems.
Pulling a vacuum, with a "MityVac", on pump reservoir, and running the engine, is the fix.
Vacuum on steering system, will remove "air" from the total system.
Had upper power steering hose replaced now there is a constant roar from engine area not depending if I turn wheels or not. All fluids okay
