Holden HSV Grange Engine Number
Use this guide to locate the engine number on your Holden HSV Grange and line up the right engine-related parts enquiry.
The HSV Grange was Holden Special Vehicles' long-wheelbase (LWB) luxury-performance flagship sedan, built on the Holden Statesman/Caprice LWB platform and powered by LS-family V8s across the WH, WK, WL and WM series from the late 1990s to around 2010.
Where to find your Holden engine number
The stamped engine number is on a machined pad on the block. Its location depends on the engine family:
- Inline six-cylinder: on a pad on the right-hand side of the block, above the engine-mount boss.
- V8 (253 / 308, 4.2 / 5.0 litre): on a pad on the left-hand side of the block, above the engine mounting.
- V6 (Buick-derived, Ecotec, Alloytec): on the front left-hand face of the block, below the ignition coil.
- Later V6 and LS V8 models: the build / engine plate sits on the radiator support panel (VT-VZ era) or the passenger-side strut tower (VE / VF era).
You may need to wipe the pad clean to read the stamped number, and on air-conditioned cars the compressor can sit in front of it. Older Holden engines use a capacity-plus-tune prefix (for example 186S or a Q-series V8 code), while modern engines (Ecotec, Alloytec and the LS V8 family) use a GM engine code plus a separate stamped serial.
For the most accurate part match, send us both the engine code or prefix and the full stamped number, along with whether the car is automatic or manual.
On this model
The Grange used Holden's LS-family V8s, with the specification varying by series: earlier WH/WK/WL cars were typically fitted with the 5.7-litre Gen III (LS1) V8, while the later WM generation moved to larger-capacity LS-family engines (such as the 6.0-litre and, in later builds, 6.2-litre units). To order engine parts accurately, quote the exact series, the V8 engine code and the stamped engine number, and confirm the HSV specification, as HSV tuning and hardware can differ from the standard Statesman/Caprice V8 of the same era. Where the fitted engine is uncertain or may have been changed, verify the code and stamped number against the vehicle before proceeding rather than assuming the factory unit.
This page also draws on later year-by-year data for Holden Grange to cover modern variants.
Frequently asked questions
Where is the engine number on a Holden HSV Grange?
It is stamped on a machined pad on the engine block. Inline sixes are on the right side above the engine mount, the 253/308 V8s on the left side above the mount, and the V6 engines on the front left face below the ignition coil. You may need to wipe the pad clean to read it.
What is the difference between an engine prefix and an engine code?
Older Holden engines use a capacity-plus-tune prefix stamped on the block, while modern engines (Ecotec, Alloytec and the LS V8 family) use a GM engine code plus a separate stamped serial.
Do you match engine numbers to parts?
Yes. Send us the engine code or prefix and the full stamped number, plus whether the car is automatic or manual, and we will match the right engine-related part.
