Dayco® OAPs (Overrunning Alternator Pulleys) allow the alternator to ‘freewheel' when the belt speed drops and they are engineered with one-way clutches that allows the rotational inertia of the alternator to “overrun” during any belt deceleration event. Dayco® OAPs, which are designed for long service life, decrease drive belt vibration and reduce belt slippage during rapid acceleration or deceleration, resulting in reduced stress on the drive belt and other accessories as well as increased alternator and drive belt life. Dayco® OAPs are application-specific replacement parts. If a vehicle requires an OAP, the same type of pulley must be installed. Proper tools must be used to remove and install OAPs.

Customer Questions
Will the alternator drain my battery?
No, the alternator is not designed to drain the battery. Instead, it charges the battery while the engine is running. If your battery is being drained, it could be due to a variety of factors, and it's recommended to have your vehicle inspected by a mechanic.
How do alternators work?
Alternators convert mechanical energy from the engine into electrical energy to power the vehicle's electrical system and charge the battery. They consist of a rotor, stator, and voltage regulator, which work together to produce electrical energy that is used to power the vehicle's electrical components and charge the battery.
Which alternator do I need?
To determine which alternator you need, consider your vehicle's make and model, engine size, and electrical system requirements.
Which alternator system is controlled by the PCM?
The variable voltage alternator system is commonly controlled by the PCM in modern vehicles.
