Q: alternator we put on car is sqeeling

asked by on

Changed alternated and now something on the belt or alternated is sqeeling

My car has 17000 miles.
My car has an automatic transmission.

Since you just installed the alternator you may not have adjusted the belt tight enough. The new alternator is charging at a high rate due to the low battery. If this is the case, the loose belt may need to be tightened.

I’d suggest getting an inspection from a qualified technician, such as one from YourMechanic, to diagnose the sound and help you fix it accordingly.
