What is your question?
Above 1500 rpm belt squeals at power steering pump pulley. Vehicle has new blet, power steering pump and hydroboost. Not sure why it is squealing. New tensioner and idler pulley aslo. Everything lined up. I have adjusted the pulley alignment several times. I spray water on pulley it stops squealing for a second. Thats how I know where it is coming from.
How long has your 2019 GMC Sierra 3500 HD had this problem?
More than a week

Hi - Dave here, contributing to RepairPal and providing expert advice since 2010. This is something that only can be resolved hands-on, not by technical information, communication, not by theory and operation. The truth is - something has to be amiss. And this is only something that can be seen physically in person. I suggest a technician from a local shop get a set of eyes on it to see what's going on. https://repairpal.com/auto-repair-near-me Click the link to find some shops near you who can help out!
