Holden Rodeo Engine Number
Use this guide to locate the engine number on your Holden Rodeo and line up the right engine-related parts enquiry.
The Rodeo is Holden's Isuzu-based one-tonne ute, sold here through the TF (1988-2003) and RA (2003-2008) generations before being renamed Colorado in 2008. It was offered in 4×2 and 4×4 with single and crew-cab bodies, in petrol and diesel.
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
Rodeo used a range of Isuzu diesel and petrol engines across the TF and RA; the RA's 3.0-litre 4JJ1 diesel carried into the early Colorado. On the RA Rodeo the engine number is stamped in two places — on a plate in front of the radiator and on the cylinder block. Send the engine type and the stamped engine number so the correct part is matched.
