Should the power steering pump pulley spin freely?

Recommended Posts

MY 2000 - 996 Cab with 54K miles

Should the pulley on my power steering pump spin as freely as the pulleys on my alternator and water pump? I have been trying to track down a high pitch hum/squeel at certain speeds and I checked the pulleys today. The pulley clearly doesn't spin like the others. I checked this last winter when I replaced the water pump and I don't recall any tension in the spinning of this pulley at that time.

It won't rotate as freely as the alternator but should have no roughness or tight spots.

I just placed a post about the movement and noise of the PSP pulley because while doing my water pump I noticed the Pulley spins freely but makes some noise...I.e. not quiet like the other pulleys. Did your pulley present any problems...did it make any sounds...what was the end result.

My 04 has 17K miles and this is preventive maintenance. I started to wait until more miles or signs of leaks but since the warranty starts at the time of purchase I thought I should get it in there. Also a tech I trust recommends the 2yr or 15K interval. I've read on these forums failures from cars with low and high miles.

If you rotate the pulley by hand, the pump can squeak. This is normal and not audible with the engine running.

      I need to remove the crankshaft pulley from my 2000 C2 Cab. Does anyone have tools 9285/1 and 9290 that they would like to sell?

      I have a 2003 Boxster with 77,653 miles. I am the third owner and this Tiptronic Porsche was brand new in late December 2002. It is my daily driver and most of its miles are on the highway. It hasn't been tracked.
      Roughly two weeks ago the coolant temperature blinking light came on for roughly a minute. It has come on once since then. Each time the engine temperature was perfectly fine throughout the 1 1/2 trip. I did not until today check the coolant level (my bad) and now see that the fluid is well below the minimum level but can be seen when looking down through the opening.
      On the way home from San Antonio for Thanksgiving I heard a new cyclical noise that sounds like bearings going out. I've read up on different websites that it is likely my alternator, pulleys, or water pump. My battery registers 12.6 volts when the engine isn't running and 13.93 when it is running. I bought a mechanics stethoscope and as best I can tell the water pump and the lower pulley seem to have rough noises. And there does seems to be the smallest flutter in the water pump pulley with it going in and out maybe 1 to 2 mm.
      Here's a link to a short video (

      ) of the engine running and you can hear what I think is a bearing going. Would the next step in isolating the problem be to remove the drive belt and try spinning the pulleys and water pump pulley freely to see if there is any obvious failure going on? I tried the WD-40 trick but spraying it on the pulleys while running didn't make any obvious difference. If it is the pulley and/or water pump how difficult are those fixes if I'm handy and have in the past replaced a turbocharger on my old Saab 900? I don't fear much in the way of fixes (perhaps to a fault). Please share your wisdom or I'll end up spending too much at a shop. :-)
      Thanks,

      Replacing the water pump on MY04 C4S and after removing serpentine belt the check of pulleys revealed a noise in the power steering pulley in both direction. There are no drivability issues at this time. The cold fluid level is per spec.
      The alternator spins freely clockwise but makes a little clicking noise counterclockwise.
      Are these signs of pending or existing problems which need to be addressed. All my forum reading only mentions noise while car is driven. Any comments appreciated and Ill check back while I continue on the water pump replacement. I have attached a pic for reference

      Hi. I was supplied with a replacement (recon) alternator for my 2002 Boxster S but it had the solid pulley fitted instead of the freewheeling / overrunning clutch type.
      My garage fitted it anyway but found that it only charged at 8.4 volts. The alternator supplier is telling me that the reason it only delivered 8.4v was due to the incorrect pulley being fitted rather than any internal fault with the alternator which I find difficult to believe.
      We fitted another alternator with the correct pulley & this one charges fine.
      Has anyone any experience of running a "solid" alternator drive in place of the "freewheel" type please? Does it in fact result in a lower charge output or is this a red herring by the alternator supplier to avoid picking up the second set of labour charges.
      Thanks

      99- 996 with trip.
      With the help of the forum (quick thank you) I was able to determine that I had a bad bearing/idler pully. I have removed the air box and am trying to determine: 1. the correct torque for the attaching bolt on the upper idler, and 2. does it require a specific spanner or wrench, or can i use a common open/box end? Also there was a great video (shows removal of box and how to on the tensioner) when I first looked at how to do this but I have since grown a few days older and cannot remember the search words i used. Any ideas?
      Thank you in advance for your help.
      Serg
