Cheap Nissan 370Z Alternator

The 370Z ran as a single generation from 2009 through to around 2020, with a facelift arriving in 2013, so both years sit within the same generational family and share the VQ37VHR petrol engine. That said, mounting brackets and ancillary details can change mid-production, so whether a 2009 unit bolts straight onto a 2015 car is something you should confirm with the breaker against your specific registration rather than assume. Supply your engine code from your V5 or a VIN check — that gives the breaker the clearest basis for a match.

The 2013 facelift updated styling and some interior and suspension details, but the 3.7-litre VQ37VHR engine carried over across the facelift boundary. Because the alternator follows the engine rather than the styling revision, a pre-facelift and post-facelift unit may well interchange, but ancillary mounting changes at the 2013 point are something you should confirm with the breaker against your registration before buying. Quoting your engine code alongside your year gives the breaker the best chance of verifying the fit.

For a mechanical part like an alternator, trim level does not drive fitment — the engine code does, and all UK-market 370Z variants used the same VQ37VHR 3.7-litre petrol engine regardless of trim designation. A GT, GT Edition or any other badge variant should all point to the same alternator specification, so there is no need to chase a trim-specific part. Bear in mind that cosmetic and interior differences between trim levels are real, but they have no bearing on which alternator the car takes.

Yes, output rating can matter: if your car has a higher electrical load from factory-fit options, it may have been built with a higher-output alternator, and fitting a lower-rated unit could cause charging issues. Cross-reference the amperage on your original unit and mention it to the breaker when requesting a quote. Your engine code and full registration will help the breaker check whether your specific build used a uprated unit.

The 350Z used the earlier VQ35DE or VQ35HR engine rather than the 370Z's VQ37VHR, so the two alternators are not the same and should not be treated as interchangeable. Always match by engine code first — the VQ37VHR in the 370Z is specific enough that the breaker will need to source a unit confirmed to that code. Mentioning both your engine code and your registration when getting a quote will help avoid a mismatch.

Gearbox type generally does not affect alternator fitment directly — the alternator is driven by the engine and its specification follows the engine code rather than whether the car is a six-speed manual or seven-speed automatic. However, if the automatic gearbox variant added extra electrical demands at the factory, there is a small chance of a difference in output rating, so it is worth mentioning your gearbox type to the breaker alongside your engine code just to be thorough. Never assume fitment without the breaker confirming against your registration.
