Hi there. Usually a high pitched sound as you are describing is caused by a bearing, pulley or belt that is worn out. Since there are multiple possible sources under the hood of your vehicle that could cause this noise, it’s best to have a professional mechanic complete an inspection at your location. This will allow them to isolate the source and recommend the right repairs.
