What does an alternator belt do?

The alternator belt’s job is to transfer power from the engine crankshaft to various other components; these include the alternator (of course), the air conditioning and the power steering.

What are the symptoms of a malfunctioning alternator belt?

Below are the top three symptoms that could indicate you need an alternator belt replacement:

• A squeaking sound from under the bonnet when you start your engine, or a high-pitched squeak while the engine is running.
• If your car stalls regularly, or the engine refuses to turn over, it could be down to a slipping or broken alternator belt.
• If you feel your car’s steering is heavier than normal, this could be due to a lack of power transferred to the power-steering system, and could also be down to the improper performance of your alternator belt.
