Subject: Power Steering: leak and pressure switch ?
On the return leg of the first road trip since our 89 Westy got a new
VW reman engine, it was raining and the rear wiper wasn't doing a
good job of keeping window clear (new blade too). It was nighttime
and a Westy, so rear window wasn't useful anyway. But on the last
gas stop, I went to squeegee the glass and found the rear door was
coated with oil and there was a drip on muffler, motor mount bar, and
right head! Oil was blowing back due to the finely tuned aerodynamics
of the Vanagon body. Oil level wasn't down by much, so I drove it
the rest of the way home and two days later, to the dealer. They
found it was a power steering leak and said the oil was down due to
normal oil usage when seating rings. (I did first oil change at 700
miles, second at 2000). That was good news! I said I can handle
that repair and took it home.
Now, looking it over, I see the pump and the send/return lines
fittings are definitely coated all around with oil. I want to spray
clean it all off with some degreaser, drive it a bit, and see if the
leak is at the seal between the two sides of the pump housing, the
shaft seal, or the send/return fittings. If it's the housing or shaft
seal, it looks easy to rebuild. Kits available at dealer for $30.
Or maybe they didn't replace the send/return fittings' sealing rings
when the pump was off to replace engine (if they even disconnected
the lines that is).
So I wonder:
1) What kind of degreaser is safe to use - I'm hesitant because of
the fat rubber head gaskets. I don't want to use anything that
might damage anything on the waterboxer.
2) The Bentley says to use new seal rings on the lines. Anyone ever
really do this ? They appear to be a metal ring, not rubber.
3) The Bentley says to use tool VW681 to remove old shaft seal. Will
a special tool really be necessary ? If so, I guess I'll just use
a rebuilt pump. But it would be nice to save the bucks and have
the pleasure of doing it myself, as long as it's not masochistic!
4) There are wires at the end of the high-pressure line, like for a
sending unit. Bentley doesn't show it in the steering chapter,
but electrical diagram on 97.125 shows a PS pressure switch. I
don't recall a dummy light for the PS on the dash ?! And the
diagram shows it wired to the Digifant control unit relay and the
idle stabilizer control unit. Why is the PS wired to the FI ? If
you lose PS pressure, does it make you slow down ?
