Power steering pump connections high and low pressure outputs

Hi I am installing a BMW steering pump into a custom application. It uses a similar application with steering and brakes sharing hydraulic pressure. Does anyone know what the three lines connect to from the pump. One is reservoir and the other two are high and low output pressure I believe. I'm just not sure which ones connect where.

Top rear most line comes from the pressure regulator, rear side outlet at angle line goes to oil cooler then to fluid reservoir. Smallest of all three lines is a pressure line that goes to the rear self leveling system.

Power steering hi i have a saab 95 year 1999 when turning all the steering till the end the rpms drop and oil light turns on. either engine oil and steerng are at level. while driving nothing happens, and...


Possible fault areas; oil pressure sender not accurate,
low oil pump pressure output,
RPM dropping below 300rpm under load,
computer not compensating fast enough,
dirty throttle body,
oil viscosity too thin,
I would probably start with an oil change going with a thicker grade especially if you have high mileage.

Power steering hose diagram


power steering hoses run from pump to the steering box, (high pressure) and from the steering box to pump (low side).. is a closed connection. pump to box, then from box back to pump. High pressure should have pressed on fittings, while low side may have normal water hose clamps or replaceable hose without pressed on fittings.

How to install a power steering high pressure line on a 1998 olds 88 regency


Hi,
You will need line wrenches to get the line off the steering gear assembly (tight in there near the frame sub assembly) First you will want to remove the drive belt from the power steering pump. Then remove the bolts from pump to bracket and lift pump up. On back of pump, remove low pressure line and drain fluid into a container. Under pump, remove high pressure line, and push it downward toward floor. From under car, follow the line to the steering gear, ( the line may have a keeper clamp or two for stationary support to remove along the way) then detach. Installation is reverse of disassembly........Not fun, but doable.....Mike

The line that goes from my rack and pinion to my power steering box busted. what is the name of that ghose so i can go get one


There are 2 lines that service the rack and pinion. One is the high pressure line from the output side of the power steering pump, and the other is the low pressure return line to the power steering pump.

Just determine if it's the output or return line and go to your local auto parts store.

It might not be a bad idea to also pick up a vehicle specific repair manual for precise instructions on how to bleed the lines, etc.

Shouldn't be any problem at all....just a little messy from spilled fluid.

Good luck!
