Parts for your 2010 Holden Commodore-Oil pump

2010 Holden Commodore oil pump — what it does and when to sort it

Yes, the 2010 Holden Commodore absolutely uses an engine oil pump. Technical sources including the Holden VE Commodore/VE Series II Workshop Manual (Engine Mechanical sections for the HFV6 and Gen IV V8), GM Global Service Information (GSI), and GM Powertrain documentation specify a crankshaft-driven, gerotor-style oil pump mounted at the front of the engine (integrated with or behind the front cover) on both the 3.0/3.6 HFV6 and the 6.0 V8 variants. It’s a core part of the lubrication system on every petrol engine offered in that model year.

The oil pump’s whole job is to pull oil from the sump and push it under pressure through the galleries to bearings, camshafts, lifters, timing gear, and—on engines where fitted—variable valve timing and cylinder deactivation hardware. On the Commodore’s HFV6 and Gen IV V8s, consistent oil pressure keeps the engine quiet, the timing gear stable, and the internals protected at every rev. When the pump is healthy and the oil is the right grade, the engine copes with Aussie and Kiwi conditions with no dramas.

It’s not a regular replacement item, but it relies on clean, correct-spec oil to live a long life. Sticking to the logbook service interval, using the grade and specification Holden called for, and replacing the oil filter every time are the best ways to keep pump wear down and pressure spot on. If the oil pressure warning lamp flickers, the engine gets rattly on cold start, or there’s persistent lifter tick, it’s time for a pressure check with a mechanical gauge and a look at the sender and filter before pointing the finger at the pump.

• Common warning signs: low oil pressure light, noisy lifters or timing gear, metallic knock under load, or fault codes for oil pressure control where applicable.
• Good practice during major work: if the front cover is off (timing chain work on V6, front seal or timing set on V8), inspect the pump, relief valve and pickup O-ring, replace if there’s scoring, excessive end clearance, or suspect wear.
• On refit: prime the pump with clean oil, use fresh gaskets/seals, and torque fasteners to the workshop manual spec.

Actual pump replacement is a decent job—harmonic balancer, front cover and timing gear access required—so most owners tackle it alongside other front-of-engine work. Using a quality pump (genuine or reputable aftermarket) and the right oil afterwards will keep the Commodore happy for heaps of kilometres.

Popular questions

Does the oil pump need replacing as part of routine servicing?

No. Under normal conditions it’s not a scheduled service item. It’s assessed if there are oil pressure concerns, high kilometres with front cover access, or when doing timing chain (V6) or timing set/front seal (V8) work. Regular oil and filter changes are the best preventive care.

What are the signs of a failing oil pump on a 2010 Commodore?

Look for a low oil pressure warning, persistent top-end rattle after warm-up, or lifter tick that doesn’t resolve with correct oil. Always confirm with a mechanical gauge and check the pressure sender and filter first, as these are cheaper and commonly at fault.

Should the pump be checked during timing chain repairs on the V6?

Yes. With the front cover off, it’s sensible to inspect the pump rotors and housing, relief valve operation, and the pickup O-ring. If wear or scoring is found, replacing the pump and seals while you’re there can save doing the job twice.
