Dayco 5050325 serpentine belt for the 1985-1991 Toyota Corolla and other vehicles turns the engine's accessory pulleys from the crankshaft. Depending on the vehicle, this Dayco serpentine belt runs the alternator, fan, water pump or air conditioning.
A squeal from the front of the engine, a battery warning light or weak air conditioning output can mean the belt is worn, though a weak tensioner or a pulley that is out of line can be behind them too.
The 1985-1991 Toyota Corolla, the 2009-2011 Mazda RX-8 and the 2006-2008 BMW Z4 6-cylinder 3.2L all take this belt, one per car, and so do a wide range of other vehicles.
