My car makes this high pitch squealing/squeaking noise when after I break for a light, then lift my foot to return it to the gas pedddle. Also, when I'm backing up, it squeals, and when I turn left it whines. When I stop at my destination, it squeals for a few seconds (2-4). Sometime, while I'm driving, it squeals/squeaks. None of these high pitch squeaking, squealing or whining sounds are constant. They always stop for a while, then I'll hear one again.
On June 6, 2013, I had the ignition and the front wheel hub bearing replaced. On August 26, I had the alternator replaced along with both the rear upper ball joints. The serpentine belt was not replaced (I was told it did not need changing). On September 4, I had the a/c compressor, drier and expansion valve replaced.
I have been told that I need my radiator hoses and heater hoses replaced. Is it possible that something was damaged or left undone during one of these repair?
I purchased my car in July of 2009, and I don't know if these hoses have ever been changed. The previous owner was a company, which according to the carfax maintained it well(there was no other owner). I currently have 150,094 miles on my car. Also can you tell me what I can expect to pay for the radiator and heater hoses replacement.
