Squealing on start-up
Especially on cold or damp mornings.
That squeal on a cold morning is usually a drive belt slipping. We replace worn belts — and the tensioner and pulleys if they’re the real cause — before the belt snaps and takes your power steering and charging with it.
The drive belt (often called a serpentine or accessory belt) runs off the engine and drives the alternator, air-con compressor, power steering and sometimes the water pump. If it breaks, the battery stops charging and the engine can overheat.
Belts are rubber, so they harden, crack and stretch with age. A worn tensioner or noisy idler pulley is often the hidden cause of a squeal, so we check the whole belt drive rather than just swapping the belt.

Visible cracking across the belt’s ribs.
The alternator isn’t being driven properly.
On cars with belt-driven power steering.
Good to know: A replacement tensioner or idler pulley is quoted separately if it’s worn.

Noises, warning lights, when it happens — photos and videos help.
We find the cause on site and you approve a fixed price before work starts.
Repaired where it’s parked, tested, and you pay when it’s done.
You’ll lose charging, power steering and air-con, and on some engines the water pump — so the car can overheat. Pull over safely and call us.
Check your logbook; many manufacturers suggest inspecting it at every service and replacing it when cracked, glazed or noisy.
No. The drive belt runs the accessories on the outside of the engine. The timing belt is inside and keeps the engine’s valves in time — a much bigger job.
