i use my 97 4 cyl. for snow plowing and went to put it away for the summer- when I started it there was a squealing sound and then the Serp. belt which i had replaced in Sept broke off?? What would cause the new belt to break??- With no belt on should all the pullies be able to spin??- thanks
No smoke- do not remember about burning smell- it happened so fast- what would cause the squealing?- I tried spinning the pullies - the idlers spin freely does the jeep need top be running for the other pullies to spin-
Yes they all should spin easily except for the one connected to the crank shaft. Cant think of which one it is at the moment. alternator, a/c (if you have it), power steering, and I think an idler pully or two.
Make sure all the pulleys are inline. this may sound strange, but a friend of mine has an older VW and we didnt pay attention when we put the new belts on, but one of the mounting bolts for the ac compressor had broken, so when we tensioned the belt it bent the remaining bolt and the pulley stuck out a good half inch farther than the rest of them. the belt lasted about 40 minutes after that.
If your going to be leaving the vehicle sitting for the summer, you should runn it for about a half hour once a month during the summer, just to dry out any moisture that might get into into with the heating and colling during the summer.
What have we got?
We have one heavily armed Recreational Vehicle
All the rest are driven by the crank pulley so they should spin freely. The squealing was more than likely one of them with the bearing freezing up. Since the teeth on the serpentine drive things I would check the tensioner (no teeth) smooth = squeal.
great guys thanks-The reason I am asking is that the pulley on the alt. did not spin when i quickly checked- Not sure if the power had to be on for it to spin???? Does this mean that my alt. is shot??? thanks so much for all your help!!
you can replace the bearings in the alternator. You don't need to buy an alternator just because the pulley won't spin. Theres a nut inside the pulley. This is where you attack it. Before you take out the four bolts on the side of the alternator that hold the casing together, make sure you mark the side of the alternator with a crayon or marker so you get it lined back up properly after you take it apart.
also, be wary of autozone and advance alternators. Not the best rebuild jobs. In case you didn't know, all alternators and starters are rebuilt, unless you specifically state over and over that you want a new one. And you can buy a winch for the price of a truly new alternator or starter. I suggest you find an independent parts store that works on alernators and starters. Its usually one part in the alternator that stops charging and it will cost you half the price of a rebuilt one to change out the one part. Thats what you are buying out of the box anyways, an old housing with new internals.
thanks so much guys you are the best!!- I think I am going to get a new one just to be safe- Since mine is a 1997 4 cyl with a/c- it gets the 117 amp one??- when I called carquest they only show a 90?? thanks again
