Power Steering Pump Overheats, Whines
My '64 GTO has the original pump (with new front seal, "O" rings) with a IROC Camaro steering box from NAPA.
Power steering works fine for about 10 minutes after a cold start. Fluid heats rapidly (at idle with steering wheel centered). Pump is quiet until fluid gets hot--then whines when turning the steering wheel or revving the engine when wheel is centered. System now has power steering fluid as NAPA recommends instead of Dexron. I've driven the car about 25 miles since steering system has been in place but heat and whining problem does not appear to be getting better. I have a power steering pump control valve from a late '70's Chev pickup truck, which used the variable ratio faster box. Will this help my problem? If not, any ideas on how I might correct this problem? Adding a steering fluid cooler is not an option. These cars had no coolers on them when new and should not need one now.
