This is my first post, unfortunately. It has to be about an issue I’m having with my beloved truck. I have a habit of staying ahead of the curve and solving problems before they occur on my truck because I really like it and want it to last, also, it already has 165,000 on it and it’s an 07.
I recently changed the idler pulley, tensioner (the whole assembly), and put a new belt on it. Ever since I have done that, I have had a chirp. I used the word chip because it’s high pitched it reminds me exactly the noise a cricket makes. This happens especially when it’s cold(er) out, and under acceleration. It also does it while cruising on the freeway and when I take my foot off the accelerator, it at time will continue doing so. When it gets warmer temps out, it continues to do this, just not to the level it does with colder temps.
I’m new to the area where I live, so I don’t really know any mechanics I could ask or pick their brain. Every time I do ask around people, I get a different answer as to what it could be. So I turn to you!
Any help is much appreciated, thank you.
P.S. The truck is just a basic 2007 GMC Sierra 1500 Classic, Work Truck Model, 4.3L V6, Automatic.
