2004 Yukon XL whistle with belt off
Hi Ive had a problem with my yukon xl with the 5.3L Vortec. It has been making a very high pitched whistle sound that matches rpms. I have replaced the alternator, ac tensioner pulley, and the ac belt. It also makes the sound with the serpentine belt off. I have also sprayed brake cleaner around...- zachreilly0
