I recently replaced the power steering pump on my 1998 Buick Lesabre. I replaced it with an AC Delco pump and flushed the fluid with Valvoline Max Life P/S fluid. After bleeding all the air out I seem to still have some noise from the pump once the fluid heats up and the steering is sometimes a little tough when this occurs. I'm going to flush and bleed the fluid again, however I'm going to use the GM/AC Delco P/S fluid this time, but I can't seem to match up the old parts numbers from the owners manual to the new fluid part numbers. This is what the manual states: GM Power Steering Fluid (GM Part No. 1052884 - 1 pint, 10500 17 - 1 quart, or equivalent). Can someone please give me the current AC Delco P/S fluid part numbers that replaced the GM numbers from the manual? Thank you!
