Holden Commodore

The car the marque was built around, and the reason Holden gets pages at all: from 1997 this is a rear-drive saloon engineered in Australia, sold nowhere else under this badge, and exported instead as the Pontiac G8, the Chevrolet SS and the Vauxhall VXR8. The VT to VZ cars are widened, re-engineered developments of the Opel Omega B, so Omega information reaches some of the body and suspension; the VE of 2006 is a clean-sheet Australian design on GM's Zeta platform and shares almost nothing with any Opel. Engines are the Buick-derived 3.8 V6 and, later, GM's High Feature V6 and the LS-family V8s — so LS information from a Corvette or Silverado applies directly to the V8s. The recurring faults are the 3.8's plastic intake manifold and its coolant elbows, and on the LS cars the usual lifter and cam-sensor items.

Information, not instruction

CarGeek is a reference, not a service manual. Its pages are written from public sources and from what other people have found, never from a manufacturer's own service information, so they can be wrong or incomplete for your particular vehicle. Some of what they describe carries real risk: high voltage, fuel under pressure, stored energy, hot and moving parts.

Have anything you intend to act on checked by a trained person against the manufacturer's own procedure for your vehicle. Nothing here replaces that procedure.

Nothing posted about this yet. Whatever you found is worth writing down — even a dead end saves someone the same afternoon.

What makes one worth reading:

The car — make, model, year and engine. The same fault behaves differently on each.
What you measured, not only what you replaced.
What actually fixed it — or that nothing did, which is worth knowing too.
