1974 Buick Riviera Parts

The item arrived in an over size box that had the pump sliding around in limited packaging. The tank was painted over a clearly not cleaned before painting. The paint on reservoir flaked off easily to show a greasy oily surface. Installation was a pain to line up bolts to holes. The return line was in a position blocking access to hole on bracket to pump. Not sure what car the reservoir was originally from. Once I got it installed I filled the Reservoir with Power steering fluid I bought at Advance Auto Parts. I left it to sit on engine over night because I ran out of fluid. I installed a new belt for all accessories. I started the flush process using 1 gallon of fluid that finally came through clean. Need at least 4 fills & drains to get fluid to come out clear & no bubbles. I then attached the return line with filter. Some were in ordering I got a case on filters? I ran the engine to warm up fluid. Turning steering wheel lock to lock many times. I went for a shake down ride & the terrible screeching sound from pump was gone. Smooth operation restored.
