Specialist reconditioning of alternators for Astra, Zafira, Vectra, Corsa and Combo — OE-spec bench tested, rebuilt to original specification, and backed by a 12-month warranty. Fast UK dispatch from Coventry.
The most common early sign - the alternator is no longer keeping up with electrical demand.
Not about the battery itself - it means the charging system voltage has dropped out of range.
Often a worn bearing inside the alternator rather than the drive belt.
If a new battery goes flat again quickly, the alternator usually isn't charging it properly.
Send your 17-digit VIN and symptoms - we confirm the exact alternator fitted to your car.
We supply an already reconditioned, bench-tested alternator on exchange - your old unit becomes the core, refundable deposit applies.
Fit it yourself, or we fit it at our Coventry workshop. Every unit is covered by a 12-month warranty.
Our Vauxhall/Opel alternator stock covers Astra, Zafira, Vectra, Corsa and Combo - the exact unit depends on your specific engine and model year, which we confirm from your VIN.

No - the same Vauxhall/Opel model can use several different alternator variants across its production run. We quote from your 17-digit VIN, which confirms the exact unit fitted.
We can't decode a unit from a registration number alone — have your 17-digit VIN ready (V5C, dashboard or door frame).
