740gle Posted November 14, 2009 Share Posted November 14, 2009 Squeaky sound from under the hood in the mornings, and mornings only. no cat, squirrel, or chipmunk jumping out... Rather, It seems to be the PS belt because when steering first time out of the driveway is when the screeching is the loudest. Goes away after warm up. Yet to accurately measure the belt tension, but quick look didn't see anything too loose there. Is it just a belt, or is PS pump going to die on me? Is there a simple remedy to the noise? Soap on the belt? Any hints on belt replacement job? Is belt expensive? I tried to search on-line, but only found an AC/alternator belt, which was about $12.

Legacy777 Posted November 15, 2009 Share Posted November 15, 2009 It sounds like just the belt. I'd suggest getting a new belt. Shouldn't be more than $10-$20 at the most. Quote Link to comment Share on other sites More sharing options...
Rooster2 Posted November 15, 2009 Share Posted November 15, 2009 It is an ez install, since the belts are at the front of the engine. Quote Link to comment Share on other sites More sharing options...
740gle Posted November 15, 2009 Author Share Posted November 15, 2009 Are the two belts - the one that drives AC and the one that drives PS pump the same? Quote Link to comment Share on other sites More sharing options...
Fairtax4me Posted November 15, 2009 Share Posted November 15, 2009 The alternator belt drives the PS as well. AC belt should be separate. Quote Link to comment Share on other sites More sharing options...
740gle Posted November 15, 2009 Author Share Posted November 15, 2009 Sorry, I wasn't clear. Are these two belts the same length and type? Can they be interchanged? Quote Link to comment Share on other sites More sharing options...
Fairtax4me Posted November 16, 2009 Share Posted November 16, 2009 I don't believe they are the same no. Pretty sure one of them is a tooth wider. Quote Link to comment Share on other sites More sharing options...
98obster Posted November 16, 2009 Share Posted November 16, 2009 dealer should sell both belts as a set. I've had the squeel in the mornings (winter only) for a couple years, I also have a Perrin crank pulley. I just think of it as a part of life. like when when a plane's tires hit the ground. could be PS pump bearing-but I doubt it. Quote Link to comment Share on other sites More sharing options...
740gle Posted November 16, 2009 Author Share Posted November 16, 2009 Well, it does correlate with cold mornings.. What's Perrin crank pulley? This summer when the dealer did a headgasket job, I thought they'd replaced the belts also. Quote Link to comment Share on other sites More sharing options...
