If I'm doing some tight maneuvering like parallel parking or turning around on a one-lane dirt track (as I did several times on Mon & Tue looking for good camping spots in SW Colorado), I end up with the steering of my '84 Westy turned full-lock left or right. Inevitably the hard-working power steering unit stalls out the engine, usually at a really inopportune time.

Sure, the solution is to pay attention and keep the revs up but If I'm focusing on not backing into a ditch, a tree or a parked car RPM is not my main concern.

Is there a solution other than awareness? A power steering adjustment? Something else?

Thanks in advance

If you look in Bentley p.24.24b, there's the layout of the Digijet intake air plumbing for AC- and PS-equipped cars. Your should have an idle boost valve activated by a pressure switch on the PS pump. If you idle your engine and bridge the two wires on the pressure switch, the idle should rise substantially. If not, the servo-valve may be faulty. Or maybe your van didn't get one.

Seems to me like there is an electrical switch at the pump which kicks the idle up a tad

check that connection/connector

unless the p/s pump is about to seize

Did this work for you?

I have the same issue now (same year van too).

EDIT:
Okay, so on my second check I have the idle boost valve but nothing is connected to the electrical connection.... Anybody have a picture on where the other end of idle booster electrical connection goes? The Bentley seems a little light on details for the electrical connector there

Pardon the slow reply. Just back from meandering in the Westy last week.

Mine had NO sensor switch attached to the power steering pump; there was a bolt screwed into the hole and the wires at the idle switch were cut. Here's what I did with the help of 10's comments and the Bentley:

Works like a charm now.
