Holden Crewman Engine Number
Use this guide to locate the engine number on your Holden Crewman and line up the right engine-related parts enquiry.
The Holden Crewman was a crew-cab utility built in Australia from 2003 to 2007, spanning the VY then VZ series and based on the Commodore ute platform to offer a rare four-door dual-cab plus open tray layout. Most were rear-wheel drive, with the all-wheel-drive Cross6 and Cross8 variants adding off-road capability to the range.
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
Crewman engines cover the 3.6-litre V6 (the earlier Ecotec on early VY cars and the later Alloytec from the VZ series) and the LS-family Gen III V8, with the all-wheel-drive Cross8 built around the V8. Because the V6 and V8 differ in mounts, cooling, exhaust and ancillaries, it is important to confirm which engine the vehicle actually has before sourcing parts. Rather than relying on a badge, verify the series (VY or VZ) and the engine type, and check the engine code and the stamped engine number on the block against the build plate. If you are unsure of the exact engine-code lettering for your specific build, have the number read directly from the engine and confirmed with a supplier rather than assuming, as it varies across the VY-to-VZ V6 change and between V6 and V8.
This page also draws on later year-by-year data for Holden Crewman to cover modern variants.
Frequently asked questions
Where is the engine number on a Holden Crewman?
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.
