i have a squeak that i can't find the source. i have narrowed it down, it is not anything to do with the ac compressor, idler pulley or belt for those. it is not the water pump or the harmonic balancer. it's probably not the alternator and i don't think it is the alternator belt slipping causing the squeak. there is one bolt on the timing cover that sticks out far enough so it actually touches the alternator belt. i borrowed a dremel from my neighbor and i was going to sand down the bolt enough so it doesn't touch the belt, but i wanted to know if that is a good or bad idea first. i am pointing at the culprit bolt in this pic, it may be hard to see because of the black glove, but you should be able to see it.

I don't see that making a squeak, but you aren't gonna mess anything grinding it down a little. |

The reason the belt is hitting the bolt is because someone put the wrong bolt in that hole. The timing cover has several different length bolts and if you put the wrong length bolt in the bottom it will bottom out and stick out far enough for your belt to rub. Been there, done that. Put the correct length bolt in rather than grind that one down. This should not cause the squeek, it'll only wear the edge of your belt down. However if it has been rubbing for a while, it will grind enough off of the BARELY adequate belt to allow it to slip and squeal.

I'd just toss the bolt out. Timing cover has ten or so of them, one won't make a difference. |

Loosen off the alternator belt and pull it off. Run the engine and see if it eliminates the squeak. I have an annoying squeak from the alt belt unless I keep it super tight. Probably one of these days my alternator will have a bearing failure due to the belt so tight.

If you still hear the squeak with the alternator belt off.... remove the valve cover and carefully examine the rocker arms where the rollers ride on the camshaft..... Had the same issue and found a bad rocker arm.... bearings on the roller were worn out and the bottom of the arm was riding on the camshaft...... later |

He's not going to find any rocker arms on his 3 cylinder. |

the car will not squeak with the alternator off. but the alternator itself will squeak a little bit if you turn it in the wrong direction. none of the pulleys had any rough spots on them when i turned them and the pulleys themselves were smooth and clean. should i just tension the crap out of the alternator belt? last time i did this the belt split and then exploded within a day. i have dayco belts on it now with a large amount of belt conditioner on them. it only squeaks sometimes. sometimes i will launch and it won't sqeuak. sometimes i will launch and it will squeak at first then go away once i shift. sometimes it will launch and not squeak and then start squeaking later. sometimes it will just stop sqeuaking. it will always start squeaking if i downshift to a lower gear to take a corner fast. every combination you can think of squeaking and not squeaking it does. |

It sounds like you've found your squeak. I've been using Gates belts. There are 2 kinds. The cheap kind, which I have never used, so I don't know if they're any good, and the not so cheap kind that last for a really long time. I still have to adjust the tension from time to time, like sometime tomorrow. I'm pretty sure the Goodyear Gatorback belts are good, too. I took my alternator apart and put it back together. While I was in there, I lubricated the drive end bearing, among other things. It's not hard to do. Here's the single post from my Project Topic. There is a video link in there that explains how to take apart an alternator and put it back together. http://geometroforum.com/single/?p=443226&t=4134400 |

i used dayco belts. they were the best available at autozone. would it hurt the belt/pulleys if i just tightened it up a whole bunch? is it gonna explode like last time? what is causing it to squeak, the belts are tensioned properly. |

What causes them to squeak? Bad design. the belts are too narrow, plain and simple. Every time the temperature drops, you have to re tighten them ot they will slip. as mentioned in my previous post, your too long bolt has ground on the side of the belt making it even narrower. You can tighten it, but it will probably rip due to wear from bolt. I don't know what they cost where you live, but they are only 7 bucks here, so why not buy a new one? Tighten the crap out of it. I run a ton of tension on mine and have never lost an alternator bearing. Why? Cause the belt is so friggin narrow it stretches.

last time i tensioned the crap out of the belt i could see the pulley ribs through the belt. then it snapped a day later. won't that just keep happening? it didn't used to do this. the squeaking started before the cold came too. :{ |

NAPA carries Kevlar belts for my riding lawnmower. Has anyone tried to find a kevlar belt for the alternator? I wonder if they even make them? Think I will take a trip to NAPA and see if they are available. |
