Russ0054 Posted November 15, 2005 Share Posted November 15, 2005 around 40k ← Go to Edmunds.com. There is a TSB that recomends replacement of the serpentine belt with a better model. Quote Link to comment Share on other sites More sharing options...

SEAN_VANCE Posted November 19, 2005 Share Posted November 19, 2005 I hvae a 98 GS 400 and from time to time the belts squeels a bit. Before changing it make sure it needs to be changed, dont just change it because of the noise. In the autoparts they sell this belt silencer spray. If your belt is good just spray someon there and youll be good for a few weeks. Mine has not sounded in a few months. Now if your belt is old, by all means change it. As far as the sunroof, sounds like a dealer issue. And your breaks...hmm, who did them? Did you use toyota pads? I got original toyota parts and my breaks are awesome.

Simple Posted November 22, 2005 Author Share Posted November 22, 2005 they cam with the car from a provate party. Non lexus brakes i guess, then they glaze over and squekky squeek. I just have to fork out some cash and replace the new brakes with new brakes. I took the car to the dealer, and they lubed up the pullies. no more squeek. Now all i have left is that darn check engine light. Quote Link to comment Share on other sites More sharing options...
super50 Posted February 11, 2006 Share Posted February 11, 2006 To the experts: Is there anything I need to know before I put some oil on my squeaky pulleys? I intend to change the serpentine belt if the squeaking does not stop after lubing the pulleys. just regular motor oil/lubricant? Any guidance is appreciated. Thanks!

There are no external oiling points on any of the pulleys - the bearings in them are sealed. Put the oil can away. Quote Link to comment Share on other sites More sharing options...
chuckb Posted February 16, 2006 Share Posted February 16, 2006 There are no external oiling points on any of the pulleys - the bearings in them are sealed. Put the oil can away. actually you can remove the tensioner pulley from the tensioner and clean it out and put a drop or two of oil along the edges of the seal. you can also get the bearing pressed out and a new one put in. here's the backside of pulley/bearing. you can see that the bearing can be presseed out and replaced.
