My 2005 imapala started making this whining/screaching noise while idling. Its stays constant even as i accelerate. I think it might be coming from the serpentine belt or serpentine wheels. Please help with any ideas.
I have had bad luck with "duralast" auto bone house brand parts.In my experience, a water pump is a water pump, doesn't really matter. As far as the guy telling you your radiator is rusted, ask him to explain how aluminum and plastic can rust. It doesn't matter how often you change your oil, the coolant flows through different passages, they are unrelated. Dexcool is not the only coolant, but you can't mix it with anything else. You can flush the entire system and run whatever coolant you want.
And to notachevyguy, show me a ford that wouldn't have the same problem if someone ran straight water in it for 2 years, read the posts before you comment, and try to make your comments useful.
That sounds good on paper. I guess I'll have to take a picture. Water boils at 212 degrees in atmospheric pressure at sea level. Every pound of pressure it is under adds 4 degrees to the boiling point, so 13 pound cap, The water will boil in my trucks cooling system at 264 degrees, and freeze at 32 degrees, which it does not see here. I'm not saying antifreeze is a bad thing, it should be run in the cooling system. I'm just cheap and lazy, and for one reason or another, it does not show rust in the water in my application. Also, I have never heard of straight water rotting out brass ( freeze plugs), but I don't know for sure. Also, I believe that it takes Iron, moisture, and oxygen to create rust.Last I checked, engines from 64 were made out of iron, which rusts when in contact with moisture. Coolant has silicates to coat and protect the iron, water does not. Water also has a lower boiling point, and higher freezing point than coolant. It also won't lubricate the water pump and will cause it to fail, and will rot out the freeze plugs.
I'm sorry I got this thread WAY off topic. Take a piece of hose and stick one end to your ear and put the other end near all of the pulleys one at a time. I know it sounds a bit red neck but it works. It will be obvious what is making the noise.My 2005 imapala started making this whining/screaching noise while idling.
