FAQs

The alternator pulley transmits rotational energy from the engine to the alternator, enabling it to generate electricity for charging the battery and powering electrical systems.

There are three main types: Fixed Alternator Pulley Overrunning Alternator Pulley (OAP) Decoupler Pulley

Common signs include unusual noises from the engine area, belt slippage, flickering lights, charging system warnings, or vibrations from the belt system.

An OAP is a type of alternator pulley with a one-way clutch mechanism. It allows the alternator to "freewheel" during engine deceleration, reducing stress on the belt and improving efficiency.

It’s possible if you have the right tools and experience. However, many alternator pulleys, especially OAPs, require specialized tools and expertise for proper installation.

A failing pulley can cause belt slippage, increased noise, reduced alternator efficiency, and eventually lead to battery discharge or damage to the belt system.

An alternator pulley typically lasts 80,000–150,000 km (50,000–90,000 miles), depending on driving conditions and maintenance.

Yes. A faulty pulley can cause excessive wear on the serpentine belt, tensioner, and potentially damage the alternator itself.

A fixed pulley rotates at a constant speed with the belt, while an OAP has a one-way clutch mechanism that allows the alternator to disengage during engine deceleration, reducing wear and vibration.

This could indicate a worn alternator pulley or bearing, belt misalignment, or tensioner issues.
