    It would have been really helpful to actually record the startup noise so that I could know for sure it’s the same as what’s on my 04 cayenne. It sounds like a metal scratching for about 1 second just on start up. Happened randomly and not always

      Metal-to-metal sounds when starting are often the starter getting stuck on the flywheel.

      Sounds like mine but it’s more screeching and only happens since it’s been cold and only does it for a couple seconds then for the rest of the day it doesn’t do it smh

    Hi, 15 outback 2.5L, squealing on cold start that goes away after 30 seconds, also does that when applying the accelerator lightly, changed the serpentine belt, tensioner is new, all pulleys are new, same thing, removed the belt completely to see if something that it spins produces noise - same squealing noise.....any ideas?

    Cold starts, it will randomly screech just until the engine is on. From turning key to letting go the screeching is already done screeching. I am not sure what it is as im not a car specialist, but i believe it may be the alternator and/or belts and/or tensioner. Thanks for any replies with advice and also your video!

    I had a sound start underneath the steering wheel where the pedals are of a loud rattle at points but when that went away my car started to squeal during start up

  • @davepg4173

    2002 Toyota Tacoma doesn’t squeal on startup only squeals when locking steering wheel either direction. Fluid was a little low. Filled to correct level and still squeals on tight turning. Would this mean that the power steering pump is bad or is going bad? No usual low fluid sound when idling or regular turns, only loud ear piercing sound on tight turns. Belt looks good, only around 3500 miles on it. Thanks

    • @HVAC_Mechanic

      Usually, it is low on fluid, or the belt is bad. If those were good, the power steering pump likely is failing.

    My car recently shredded the belt that goes around the alternator and water pump about a minute after startup a few weeks ago. I replaced the belt and the tension is good. Now it is squealing like crazy for about 30 seconds when starting on a cold morning. I am going to check the voltage in the morning and see if maybe the alternator is having to work too hard. Is it possible that it could it be a failing water pump being hard to turn?

    • @caucasianafrican1435
      @caucasianafrican1435 2 หลายเดือนก่อน

      Yes, the bearings in the water pump could be failing, even though the water pump is circulating the coolant correctly. I think that's exactly what happened to me. Alternator belt got shredded. I got a new one, but the squeal continues. Output voltage from alt is fine, and it still squeals. It must be the water pump.... I will check later tonight.

    • @HVAC_Mechanic
      @HVAC_Mechanic  7 หลายเดือนก่อน +2

      A bad battery puts a strain on the alternator, which, while working much harder than it should, puts a strain on the belt, which can cause squealing.
