Car Engine High Pitched Whine
What is a high pitched whine from a car engine?
A high pitched whine from a car engine is a common problem that can be caused by a number of different factors. The most common cause of a high pitched whine is a loose or damaged serpentine belt. The serpentine belt is a long, thin belt that runs around the front of the engine and powers the alternator, power steering pump, and air conditioning compressor. When the serpentine belt is loose or damaged, it can slip on the pulleys, causing a high pitched whine.
Other causes of a high pitched whine from a car engine include:
- A vacuum leak
- A bad alternator
- A bad power steering pump
- A bad air conditioning compressor
