Problem overview

Some Cadillac DTS owners report experiencing issues related to the high pressure power steering line replacement, including power steering fluid leaks at the connection point between the high pressure line and the pump. These leaks may necessitate the replacement of power steering system components and a refill with Cold Climate power steering fluid. Additionally, when replacing the power steering gear and pressure hose, some owners find it crucial to use a new bolt to secure the clamp of the new hose assembly to the frame. Promptly addressing any suspected power steering fluid leaks is essential, as they are a common issue that can lead to further problems with the power steering system. After the replacement, it is also recommended that owners bleed the power steering system to eliminate any air that may have entered during the process.
