[DML] Re: Alternator Squeal

["David Teitelbaum" <jtrealty@xxxxxxxxxxxxx>]

Verify that it is the alternator. One way to do that would be to start
the car with the alternator belt removed. If there is no squeal put
the belt back on. If it now squeals you have narrowed it down to the
alternator. Make sure you are using the correct belt. It MUST NOT
touch on the bottom, only the sides of the Vee. If the alternator is
the source of the squeal it is probably a sign that the bearings will
fail soon. Check that the belt is not slipping. With the motor STOPPED
grab the alternator fan and try to turn the alternator. If the belt
slips easily then something is wrong. It is also possible one or both
of the 2 idler pully bearings are bad. Just replace them, they are
inexpensive. If the belts are over 10 years old they should also be
replaced.
