Strange noise under hood with smoking.tried to reverse car back a little and then the belt the runs alternator, ac, etc breaks and then the car locks up meaning steering wheel get hard high temp sign comes on. Etc
Makes a loud squealing noise, hard to turn, battery light comes on, and slight burning smell.
Just bought my 2003 chevy impala from a private dealer, it only has 22,000 miles on it but was a salvaged title. Three days after purchasing the vehicle I noticed a loud screechy/grinding noise coming from under the hood. I've only noticed it do it a few times since yesterday, not at all times but it's really loud and annoying so we checked under the hood and it seems to be coming from the belt. I'm going to get it looked at on Monday to see what for sure needs to be replaced.
its has happened to my car 4 or 5 times in the pasted 2years.. same part keeps breaking... and fan belt falls off... my mechanic cant figure it out... should I bring to chevy dealer is it warrenty
Serpentine belt comes off every time I go through a puddle. We have had it replaced 2 times. Keeps doing the same thing.
Makes a squealing noise as I'm driving and when I first start it up. Accelerating on the gas just makes the noise louder
Started making horrible squealing noises. Noticed my serpentine belt wasn't staying on the tensioner. Tried to make it home but the belt slipped off and snapped. Bought a new belt and ALMOST had it on when the tensioner bolt broke off.
Tensioner pulley froze up and belt broke. Replaced TENSIONER PULLEY and serpentine belt...shop cost was
$156.12. Thought it was a little high but the weather was cold (15 degrees) and I didn't want to be outside working on it. You should be able to buy a replacement pulley for $35/45 and time to change requires about 1/2 to 3/4 hour. If weather was warmer I could have saved $100 plus by doing it my self.
The tensioner pulley or possibly the idler pulley, whatever one is more to the front and small, has snapped leaving my serpentine belt rubbing against mettle, and its slowly burning it away as i drive. I was told it was more than likely due to the fact that i live in Texas and the weather here is freezing on monday and by tuesday your outside with shorts on, the constant cold then hot westher caused my pulley to snap off and leave the belt on whatever holds the pulley. Is this a common problem?
same thing happened to me, the pulley assembly became loose and as I was driving the engine would shut off from loss of power at stop lights. had it replaced today and it runs new.. the spring wore out in the old assembly.
I was told by Valvoline that my Serpentine Belt was wearing out and I should get it fixed soon as possible so I did on 11\16\15.
Pully got the "squeaks", sounded like a bird genocide whenever throttling up. Replaced pully with aftermarket and all is well. Before this happened I noticed that my serpentine belt wasn't centered very well on the tensioner.
I bought a new Serpentine belt and 3 weeks later it shredded. Then I bought another one and it barely lasted a week.
