Our expert insights into alternator belt replacement
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.
What happens during an alternator belt replacement?
Our certified mechanics will:
Visually inspect the alternator belt for signs of wear, tears and cracks.

What does an alternator belt do?
An alternator belt is known by many names including the drive belt, v-belt or a serpentine belt.
Alternators are responsible for sustaining the charge of the battery so that it can power the electrical components of the vehicle. Without this key piece of equipment, the battery would die after only a short amount of driving. When an alternator is actively charging the battery, it must be constantly spinning. This spinning is made possible by the alternator belt which runs from the pulley on the alternator to the crankshaft.
The alternator belt does a very specific job and without it, the alternator cannot provide the constant charge the battery needs when the car is running. The alternator belt also drives the range of ancillary components used by the vehicle, which can include the car's power steering, air conditioning compressor, water pump and in some cases, the cooling fan. In most cars, if the water pump and oil pump are left to fail or malfunction, it can lead to severe or fatal engine damage.
Made of rubber, the belt is prone to deterioration over time, and due to its position next to the engine, excessive heat and general wear will lead to a brittle drive belt that is prone to cracking. It’s an essential part of the healthy running of your engine, so it’s imperative it’s in good condition.
