Car Forum / Volvo Cars / February 2008PS Pump noise
I put in the "new" PS pump, got the belts tight, put on the new hose, and filled the tank. Now it makes a whir noise, BUT it's not unlike that of some other PS pumps Ive heard. But since I haven't had a good PS pump in the thing (ever) and I haven't had a car with with PS period, I forgot if thats a good sound or not. It does kind of sound like the noise my dads caddie makes, and his old suburban makes, so I don't know if it's a bad noise. >I put in the "new" PS pump, got the belts tight, put on the new hose, > and filled the tank.

After filing the tank, turn the steering wheel to the stop on one side, reverse the process to the other side and do that 3 or 4 times. Top up the tank after each time you complet the left/right movement. > >I put in the "new" PS pump, got the belts tight, put on the new hose, > > and filled the tank.

Actually, you are not supposed to turn it to the end of travel all the way to each side: try to stop each turn just short of reaching the end of travel. > O > [quoted text clipped - 5 lines] > way to each side: try to stop each turn just short of reaching the end > of travel. after I did the left/right/left/right thing (not all the way) and checked the tank, it was fine. I was told the noise is mainly the high pressure in the lines causing them to resonate. There is a weight clamped around one of my lines this is supposed to help reduce that. I still hear it a little, but mainly when pulling in and out of parking spaces. >> O >> [quoted text clipped - 10 lines] > after I did the left/right/left/right thing (not all the way) and > checked the tank, it was fine. |
