It depends on the type and year of vehicle. Most of the newer vehicles use serpentine belts that are kept tight with a self-tensioning pulley. If it's an older vehicle, the alternator tension needs to be adjusted to keep it tight. Send me an e-mail with specific information about the year/type of vehicle and I'll see if I can figure it out with you. a_d_kirkwood@excite.com The car is a 2003 Ford Escort ZX2.

Can a belt moving to slow cause the battery to drain?

If it is the belt that drives the alternator, then yes. In many cars, the serpentine belt (the huge, long belt that most think is the "belt" in their car) drives the alternator, and so if it's loose or slipping, will cause the alternator to run sporadically, which will result in a battery that doesn't retain a charge like it should.


Will a weak battery cause new serpentine belt to squeak?

No, the battery has nothing whatsoever to do with the belt other than the belt is driving the alternator which recharges the battery. The alternator is working hard to recharge a weak battery. If the belt is squealing then the belt is either worn out or it is loose. If it is loose it is because the tensioner is defective and not holding the proper tension.

How do you install serpentine belt on1999 Camry?

You need to loosen holding bolt on the alternator. After that loose tightening bolt (also on the alternator). And loose the bolt attaching the alternator to the body of the engine if you do not do that you will not be able to move the alternator. After that loose the tightening bolt until you will able to remove the belt. Make sure that the alternator is loosen enough to install a new belt. Install a new belt, use the tightening bolt to set tension in the belt. The rule of thumb is you should not be able to turn belt around itself more than 3/4 turns. Tighten other bolts.
