Belt is screeching again
I just replaced the belt on my 97 SL1 this past Dec. and it has started
slipping again when first starting. I checked to see if there was any oil on it and it looks clean. I have about 174k miles on it and was wondering if the tensioner could be weak or pulley is locking up. Anyone have any of these symptoms before? Thanks a bunch, MR |

Belt is screeching again
I've had this sympton on my '95 SW2 for years. The belt squeals
sometimes for a few seconds after first starting the engine. I've changed the belt and pulled off the pulleys to check the bearings. I've concluded it's a weak tensioner. (I figure the extra load from the alternator recharging the battery after starting causes some belt slippage.) Still not sure if I'm gonna bother replacing the tensioner. The part is not real expensive, but the job is a little bit of a pain due to limited working room. |

Belt is screeching again
I've seen other posts here about weak tensioners and how they should be
replaced. Also worth if you have to take off the belt, to inspect all the grooves that they are clean and free of any compacted crud. If the belt can't seat all the way into the groove, it will slip. You are correct about the alternator load on startup. It is sometimes worse when the alternator has been replaced with a heavier duty unit which has a higher torque load. When the system is charging, the highest torqe load from the alternator is at idle. Oppie "Chuck" > wrote in message oups.com... > I've had this sympton on my '95 SW2 for years.

Sounds like a good cause for the slipping. > The part is not real expensive, but the job is a little > bit of a pain due to limited working room. You have that right. It would be nice if a fender well panel could be removed for easy access. Thanks for the input. MR |

I would recommend replacing the tensioner. And I would do it before it
comes apart while you are out on the road. My buddy is a parts guy at Saturn and he claims they see them come apart and will leave you stranded. Replace the tensioner on your terms and schedule, not your cars! I have replaced mine twice in 120K, so yours must be living on borrowed time. James |

The pulley looks as if it would be pretty easy to change, but the tensioner looks to be a real bitch to change out. Thanks, MR |

The tensioner is fastened to the motor with 2 bolts if I recall correctly.
Remove the inner wheel well liner, and access it will provide should allow you to swap it without too much fuss.

Belt is screeching again
After getting into it, I noticed that the tensioner, and idler pulley that
mounts on center of engine need replacing. The idler pulley is worn where the belt contacts and grease has come out of the bearing and caked on seals. Also, tensioner is shot and pulley on it is worn also. I am in the middle of removing the tensioner now(ran out of time last nite). It is a tough place to work with large hands even thru the wheel well. The new tensioner came with a poly pulley instead of metal. Sure hope it holds up as well as the metal one. It should as it cost $58. Thanks for the all the info from the group.

Working thru the wheel housing is the easiest, but one bolt is still a
pain, but not impossible. If I recall correctly, I used a u-joint or wobble extention. Replace both the tensioner and the idler pulley if you suspect both are bad or high milage. The tensioner will have the pulley already attached. |

It is the top bolt on the tensioner that was a pain to get out and in due to pwr. steering pulley, but finnally finished it using a few sockets, wrenches etc. > Replace both the tensioner and the idler pulley if you suspect both > are bad or high milage.

I replaced both as they had both lost the grease out of the bearings and had a groove worn in the pulleys from the back of belt contact and possibly pulley drag. I suspect that the pulleys were right at the point of self destructing and will check to see if the drag from them was causing a drop in gas mileage. Thanks again for the info. MR |
