[V8] Hydraulic system leakage

[Ingo Rautenberg]

Gunter,

Here's a rundown for you:

On my first V8, which I drove approximately 130k miles, the hydraulic pump
was replaced and the high-pressure to rack hose had to be replaced.

Mom's first V8:  Steering rack

My second V8: Nada so far

Mom's second V8:  Power steering pump rebuilt, high pressure hose to rack
rebuilt, high pressure hose to pump rebuilt.  Will need another hose
(suction to pump, I think) and steering rack rebuild/replacement soon.

My advice is to grab a few cans of brake clean and spray down the area first
and let dry.  Then watch (with flashlight) as you have someone else start
the car and gently turn the wheels (while stationary) left and right.  Then
you should see where things are actually leaking.

HTH

> Question:  Where are the common hydraulic system leaks, especially those
coming from the the region of the pump itself?  What is a normal pattern of
pump failure?

> Well, the V8 has developed a hydraulic system leak.  I don't know exactly
how fast it's leaking but a puddle of the fluid about half a foot in
diameter collects on the floor after even a short 2 mile drive.  The
reservoir is emptying itself more quickly (maybe a quart of more with every
gas fill-up), and the pace is picking up.  The source is definitely coming
from the area where the pump is.  I haven't had a chance to clean the region
to pinpoint the leak.  Car does not drive any differently (but I haven't run
dry yet ).  One of the main high pressure hoses was replaced over a year ago
with a factory original by previous owner.  The system has really not leaked
significantly all year up until now.

ALLDATA is of no help.  There is not even a schematic of the pump available
on line and I don't have a manual....sure would love to have one, though.
