  1. I've owned my 2018 Silverado for less than 6 weeks and it has been making a squeaking noise coming from the engine compartment, once the engine is warmed up. Does anyone know what could be causing this? I have an appointment to have it looked at by the dealer but I'm assuming the dealership won't be able to tell me whats wrong based on passed experience. I'll try to include a short video below where you can here the squeking noise.
  2. I have a 2015 Silverado, when turning at low speeds I have a Squealing/whining noise in the front end. Only while moving. Does anyone have a fix for this?
  3. GM-forums, I dare say I'm back for a moment or so my darlings. I need help from you folks for a most troublesome squeal that's driven me nuts for quite some time. 'A squeal? Prolly you belt,' you might say. To that I'd answer with a swift and affirmative 'No! This is unlike any squeal I've heard before, and I can't seem to find any videos with a squeal like it. Both belts are quite young, and we've replaced a few pulleys. We didn't replace the A/C tensioner pullies however. Alternator and Idler have been replaced. This squeal is loud. VERY loud. It will pretty much drown out anything within its vicinity sort of loud. I'll try to get a video up if need be. You folks are my only hope.
  4. Hello All, I am new to the forums here and feel this would be a great place to get some info.. On my 2015 Sierra 1500 5.3L (23,000 miles) there is an interesting squeal/squeak noise that I hear on cold starts in the mornings. When the engine is warm or once the weather warms up throughout the day, the start up squeak is gone. It's been going on at least twice a week for the past year and it hasn't really bugged me until now. It could possibly be the belt or a pulley.. I am very well aware of the natural noises that these direct injection engines make (the ticking of the injectors, the cranking sound on start up, etc). I will put up a link to my youtube video of the truck making the noise. (Hopefully the link works). The squeal is right at the 4 second mark. Truck is under warranty and the guys down at my dealership are good to work with so if I have to bring it in I will.. I would just like to not have to deal with coordinating my schedule, obtaining a loaner, etc.. Any input would be great.. Thanks everyone!!!
  5. Just purchased a 2014 Silverado, less than 1000 miles. A distinct squeal or chirp occurs each time the truck changes from 4 to 8 cylinders. Dealer said that nothing could be done. The noise is very annoying and should not be present in a truck that cost over 40k or any other new truck for that matter. Will continue to take it in until state lemon laws can be applied.
  6. I have had the serpentine belt squeak, and squeal on the truck for some time now. I poured over all the possible reasons why the main belt could be making noise and how to remedy it. A little bit about the test subject (whom name is Sally). 2006 Silverado with the 4.8. Mileage is 97800. Main belt replaced twice for wear and AC belt replaced once for wear prior to addressing this noise. I should have taken photos to show some highlights but I didnt, sorry. I decided to do the 100K preventative maintenance schedule on the truck in hopes of having the noise go away. Items consisted of the following: Radiator replacement (Slight gunk found in it) Complete drain, water flush with a tad of cleaning and refill of the antifreeze. Water pump replacement All hoses replaced Power steering pump replaced (had been giving a slight leak for some time). Main tensioner replaced (it was the original) Idler pulley replaced Both belts replaced with a Gator back version. Since I had all the components off at one point, the entire front of the block was hand washed, gaskets filed down and cleaned with distilled water. Front of the block was check with a simple 4 foot aluminum meter stick for trueness (you never know). Then each replaced component was reinstalled, seated and check with the same meter stick for trueness. All checked out, everything reinstalled and buttoned up. Truck started with no noise and was like that for about 2 days. Same EXACT squeak/squeal came back so all parts were rechecked, verified for trueness and actually swapped out (lifetime warranty on all of them) several times. Noise persisted until last night but I will get to that in a moment. I must give the description squeal/squeal so that others can understand. Sally would start up in the morning (either by the remote start or myself) and have the initial squeak (intermittent kind). There were days when the squeak would go away when Sally warmed up, then there were days when the squeak would stay no matter how hot (I live in Austin Texas) or how cold it got. Annoying but I could live with it for a bit. There was no pattern found in 3 months that I kept a journal on the squeak. The second noise I would get mixed in with the squeak (every so often) would be the LOUD screeching squeal that NEVER stopped. How to tell the difference: the squeak sounded like a chirp chirp and the squeal sounded like a cat being killed (I have no other way to describe it). Each sound was very distinctive and this is what had 4 shops scratching their heads. Squeak would go away, squeal would remain or squeal would go away and squeak would remain. They and I could never get Sally to shut it for more than a day (and that was after replacing the entire front end again (all belts and pulleys except the crank pulley). I would say that each shop did a superb job of workmanship and patience on trying to solve this annoyance. ALL the shops ended up refunding all the money that I spent (because they could not honor their guarantee to get the truck quiet) so I was out only the original cost of replacing the parts the first time (I did the original labor job) and left standing with Sally and her noisy self. Last night, a carpenter was at a friend's house in the middle of a bathroom remodel and I pulled up with Sally to give a hand with the remodel. Carpenter comes out of the house right after I turn her off and asks a couple of people that were helping out with the remodel, "Who was making all that LOUD racket, this is a quiet neighborhood?" They all point to Sally and he goes on to ask "Who's beautiful truck is this?" I have to take ownership of Sally's problem and start her up for this carpenter. He hears the initial noise, then asks to pop the hood. He then tells everybody to shut up while he listens to the noise with the hood up (freaking loud at that point). He then does a visual inspection of the front of the block and simply asks "This all NEW parts?" I tell him yep and he says "You run down to Home Depot to pick up some materials to complete the remodel, and I will tell you how to shut her up." I am thinking to myself "This guy is a carpenter, not a mechanic. All he wants is a free run to Home Depot..." but one of the guys sees me thinking and says "Listen to him, he has fixed all kinds of problems in the past for us. Hell, we will pay for your gas if you want to" and then proceeds to throw a hundred on the now closed hood. I say that I am game and so the carpenter gives me a list of things to pick up from Home Depot (an assortment of crap if you ask me but I ain't doing any real work on the remodel). Come back and the half the neighborhood is standing around watching me pull up. They are smiling and I am thinking "What did I really get myself into?" Carpenter asks for all the bags, fishes out one of the bottles that was on the list and tells me to pop the hood. He already had painter's tape and two handfuls of paper towels. He takes off the belt, stuffs and tapes the papertowels behind both the idler pulley and the tensioner pulley. He then takes more paper towels and tapes them on the adjoining parts to cover them (intake, other pulleys and whatnot). He then sprays quarter second bursts on each pulley, front and back, spins them and sprays more quarter second bursts while spinning. He then waits 15 seconds, takes all the tape and papertowels off. He cleans up his mess and reinstalls the belt. He fires Sally up and she is quieter than a mouse...neighborhood erupts into laughter and a lot of "I told you so" erupts. I dont believe my ears so I drag the garden hose and spray a bunch of water (because spraying water on the front brought back the noise in the past) for nearly 3 minutes, to no avail. Still quiet. I take her on the freeway and punch that stuff (toll roads ) and then come back and spray some more water. STILL no noise so I figure, "It will come back after Sally has sat overnight, a good cold soak will bring the noise back." Caught a ride home and went back this morning. Started her up and NO NOISE so I go and look at this can that he bought from Home Depot: http://www.homedepot...51#.UMyBgm-1WPs There you go folks. After 5 months of swapping new parts, visiting different shops, paying loads of cash (and then getting it refunded), documenting and researching to no avail, here a carpenter fixes the problem with 6 minutes of his day. His charge: couple of beers and two burgers made his way. He did tell me that if the original parts were on the truck, he would have inspected the idler pulley and the tensioner to verify if they were clean, if they were not cleaned, he would have made me clean them and then spray them to shut them up. If you have this problem, you just might want to verify your idler pulley, tensioner for any wear or play. If they are worn or have any play, replace them. Clean up the area and spray in VERY SHORT bursts. If you are like me and have already had everything cleaned and replaced, then this is all you need. Yes, I know that it hasnt even been a full day yet but I cant get used to the silence (yet). Next up, Airbag light *sigh* - Cueva
