Holden Zafira Engine Number
Use this guide to locate the engine number on your Holden Zafira and line up the right engine-related parts enquiry.
The Holden Zafira (TT series, sold here from 2001 to 2005) was a compact seven-seat people-mover, a rebadged version of the European Opel Zafira A and built by Opel overseas rather than in Australia. It was front-wheel drive with a 2.2-litre petrol four and used the clever "Flex7" folding seat system, and it shared much of its underpinnings with the Holden Astra (TS) of the same era.
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 Zafira TT is powered by a 2.2-litre Opel/GM petrol four from the Ecotec family, of roughly 2198 cc capacity, and it is identified by an Opel/GM engine code rather than a Holden prefix. For this 2.2 the code is commonly the Z22SE, but you should confirm this against the actual engine before sourcing parts, as running changes and variants exist. Alongside the alphanumeric code, the block also carries a stamped serial number, and it is the combination of the engine code and that stamped number that pins down the exact unit. When ordering engine or driveline parts, quote the capacity, the code read from the engine, and the stamped block number rather than relying on the Holden model name alone.
This page also draws on later year-by-year data for Holden Zafira to cover modern variants.
Frequently asked questions
Where is the engine number on a Holden Zafira?
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.
