I’ve got a Saginaw power steering pump that will stop giving assist if the engine is lugged to below idle conditions. In order to get it functioning again I can rev the engine to like 2k and assist returns as it should. To me this sounds like a sticking control valve.
My issue is finding the correct control valve. Will they all be the same? Have the pumps really changed? This pump may have been original to an early 70s Ford or Lincoln car, it could have been swapped from a 90s model GM truck outta a scrap yard. Really makes makes for an adventure.
If anyone knows a lot about these I’d appreciate any insight. I’d also prefer to replace a valve assembly with a GM or other known good part as opposed to swapping the whole pump out for an A1 Cardone reman.
