D-- Be sure to check your alternator belt tension to, every time you start any car it draws the battery down and the poor alternator has to work very hard for a few seconds to make up for low voltage in the battery. Also any time you turn on the A/C a real load is placed on the alternator and a loose belt or worn one will squeal. This type of squeal will only last a short time then quit when battery voltage comes back up to normal. A good check of both belts and tension on them is well advised. Lloyd 3502
