water pump squeal.. - 2/13/2008 2:46:55 PM    entropy   Posts: 18 Joined: 12/5/2006 Status: offline     i've had this odd squealing/screeching noise that comes and goes. i'm 98% sure it's not the belts or the tensior puller for the p/s.  all i have is the power steering and alternator (no a/c).  my hunch is that it's the water pump, maybe?  the noise comes and goes and increases with the speed of the engine but is unaffected by it.  by this i mean reving doesn't necessarily make it disappear.  any ideas?  Post #: 1

RE: water pump squeal.. - 2/28/2008 3:13:29 PM    entropy   Posts: 18 Joined: 12/5/2006 Status: offline okay, i sprayed the belts with some wd-40 with now change in noise, tempo or pitch.  i did notice though the sound was most prominent on on the drivers side of the engine.  this indicates to me it may very well be the water pump.  i stethoscoped it with no result.  until i replace the pump and that eliminates the noise i'm just going to assume that it's the culprit.  i don't plan on r&r'ing it unless it fails.  fyi, adding any electrical load didn't change the noise either.  cl8ton, do you have a link to the particular ranger forum troubleshooitng this issue.
