The belt tensioner may have gone bad, you may want to check it.
I have an 04 chevy silverado got a kinda loud squeal noise in the engine
only when i press on the gas i got a new idler,belt,alternator,steering
pump good,ac compressor good spun those no sound only thing i can think of
is tension pulley it shakes while engine on in park need help and answers
from any asap? Sumone said when i replace the belt u gota replace the
tensioner?
1aauto, I have a 94′ gmc sonoma that squeals while idling but quiets down
around 2000rpms while driveing. I replaced my idler pulley but the
squealing did not stop. What else could it be? Thanks
Anyone know where you can get new spacers? Mine had a crack in it.
did you put anything between the old bolt head and the new bearing/pulley
when re-installed? I noticed there was no hardware kit for the new pulley
as the new pulley was slightly different from the old GM pulley
@ghanemhalabi if the belt is old and cracked you may want to start with
replacing it first. If it is fairly new, then chances are that the belt
tensioner may be getting weak, and needs to be replaced.
@1aauto Could you please check out my latest video of my safari and guess
what the hell kind of noise that is please. Thank you for your videos.
Screaming or screeching could be the belt tensioner not providing enough
tension or the alternator starting to lose it’s battle with life. 10 years
is a good time to change the water pump and thermostat. Much better to tell
them when you want to change them than the other way around.
on damp or rainy morning when I start my truck up it squeaks something
terrible but only happens on wet day on the first start up would doing this
solve that….already have a new gator belt
I sprayed some belt conditioner on my 2002 silverado, and after a few mins,
it started screeching, I did sprayed with the engine running, do you think
i’ll go away after I drive it a while,, I see the tensioner moving with the
noise, do I have to replace it,
@singlecams It’s kind of hard to tell without being able to look at the
vehicle. I would check all of the steering components to see if anything is
worn out. Hope this helps you out.
@ghanemhalabi It could either be a worn belt or if the belt is fairly new,
the belt tensioner may need to be replaced. As time goes on and they get a
few miles on them they tend to loose their tension that they once had. Hope
this helps.
At first I didnt watch your video because I didnt see idler pulley in the
title. My truck now has a new pulley thanks to your video!! Thanks so much
it really helped!
Will this cause squeaking during start-up and while in gear?
How would rewind the spring
Would a clicking noise from the pulley/idler be needing replacement?
Thank you for the video, it helped me fix my brother-in-law’s truck.
@TheTommy0528 You can just replace the belt.
If you have a bent pulley some place, that could throw off the routing on
the belt and cause it to jump off. You might want to look for another issue
causing that pulley to not sit correctly anymore. Pulleys normally don’t
bend unless there was an outside force causing it to.
I’m sure you’ve gotten a million questions like this… but: I just had the
intake manifold gasket replaced. Now, at low RPM’s (1,000-1,500) there is a
sort of vibration noise. I think I tracked it down to the tensioner. Think
changing it out for a new one would solve my problem? Thanks!
Dang everytime i look for info on my blazer i always come here haaha thanks
for making the videos i had to order a few parts from you guys to
@footballbeast67123 HI at the current time we do not have an auto repair
video that shows this particular repair. We’ll keep this in mind during any
repairs on this vehicle in the future.
Are you kidding me? LOL I have just spent 45 minutes trying to figure out
how to get the belt back on my 6.0 chevy, (took the idler pulley off to get
the belt off) Watch 3 minutes of this video and Done!! Thanks I subbed!
my idler pulley was screamin’ like a banshee. i’m a ford guy. tensioner is
different. i pushed one way then the other with little results. i was
perplexed by the three holes in the front of the tensioner. then it hit me.
uuuuuuuuuuuuuutube! thanks man. you saved me. i was finished in 20 minutes.
@macdeezy2915 If the belt is very loose. It’s possible that this would
happen.
Can I just replace the belt?? Or I have to buy the pulleys too??
You do not need to install a washer on the front of either the idler pulley
or the tensioner. You DO need to switch the spacer from the back of your
old idler pulley to the new idler pulley. That is covered in the video.
Would this process work for a 96 silverado 1500?
i think i have a noisy pulley, its the wheel-thing. it has play in it. do i
have to change the tensioner assembly as well?
I have a groaning noise coming from my 2002 Blazer 4.3. I’m about 80% sure
that it sounds like it’s coming from the alternator but could it be the
idler?
I have a squealing belt, but only when the car is running idle, as soon as
i press on the gas it goes away, is that a worn bearings on one of the
pulleys?
@Dancelikeaboss You’re welcome. Have a great day!
You may have to get an air gun to shock the bolt free from the crank.
@vfbc69 Remove the belt, spin the tensioner and idler pulleys they should
spin freely with little noise Also try to move them back and forth. There
should be no play. If they have play or do not spin freely then replace
them.
how do i know the belt tensioner doesn’t work well?
hey 1aauto i have a 2002 Chevrolet Silverado 1500 2WD there a pulley next
to my ac compressor it look like its slanted and the belt it only using
haft of the pulley ween its running can that be the problem that’s why its
make nose sometime it gose off and on but when i gas it. it well make the
nose and ween i let go it the gas it stop thanks for the help
good. will follow instructions.
Any tips or secrets how to release/remove a bolt to replace a crank pulley
from a 1991 Old Cutlass Cierra? The belt keeps falling off so the pulley
needs replaced but unable to get it loose. Going on two days now trying to
get this thing loose and no luck thus far. Thy guys have tried everything.
Any tips would be appreciated.
The lock washer keeps the pulley from moving.
If the belt is old, it could be a bad belt, or a belt tensioner that has
become weak and needs to be replaced.
ok, i had to remove my tensioner pulley so i could see what i was doing
with a water pump replacement. i am ready to put the belt back on, i put
the tensioner on, put the belt on and it is now too big.. it is the same
belt that came off.. any idea what could be wrong???
thank you!
