Parts for your 2017 Holden Colorado-Oil pump

2017 Holden Colorado oil pump — what it does and how to look after it

Yes, the 2017 Holden Colorado absolutely uses an engine oil pump. Factory technical references confirm it’s a standard component of the RG-series 2.8‑litre turbo‑diesel. The GM Service Information (Holden Colorado RG, Engine Mechanical – Lubrication System) describes the oil pump’s role in the lube circuit, and the Holden/GM Electronic Parts Catalogue lists the complete oil pump assembly, pickup and related seals for the MY17 2.8L diesel. So, it’s very much relevant on this ute.

The oil pump’s job is simple but vital: push the right amount of oil, at the right pressure, to every moving bit under the bonnet. It feeds the crank and cam bearings, piston cooling jets, and the turbocharger, while helping carry away heat and contaminants. Without good oil pressure, the Colorado’s diesel won’t last long, and the turbo will be the first to complain.

As part of regular servicing, the pump itself isn’t a scheduled replacement item, but everything around it affects how well it lives. Sticking to the correct oil and service interval is the best protection. Use quality diesel engine oil that meets the spec in the owner’s manual (commonly a low‑SAPS 5W‑30 to GM dexos2 standard) and a proper filter, and change them on time—typically every 15,000 km or 12 months in normal use, or sooner if you’re towing, off‑roading, or doing lots of short trips.

Good workshop practice for oil‑pump health includes:

• Never ignoring a low oil pressure warning—shut it down and test with a mechanical gauge.
• Inspecting for sludge or sealant debris that could block the pickup screen during sump work.
• Fixing leaks promptly, low oil level can starve the pump and turbo.
• Using the correct sealants sparingly on front cover/sump joins to avoid stray silicone.

Oil pump replacement on a Colorado is a proper spanner job—not a driveway quickie. It usually involves draining oil, removing the sump and front cover, and renewing seals and fasteners. Priming the pump with clean oil and pre‑lubing the turbo feed before first start are must‑dos. Because access is tight and torque procedures matter, most owners leave this to a technician with the right tools and SI procedures on hand. If an engine has low hot idle pressure, metallic debris in the oil, or bearing wear, testing the pressure relief function and pump clearances is part of a sensible diagnosis before committing to replacement.

Popular questions about 2017 Holden Colorado oil pumps

Does the 2017 Colorado actually have an oil pump?
Yes. The Holden Colorado RG (MY17) 2.8L turbo‑diesel features an engine‑driven oil pump as documented in GM Service Information for the lubrication system and shown in the Holden/GM Electronic Parts Catalogue. It’s essential for maintaining oil pressure to the bearings and turbo.

When should the oil pump be replaced?
There’s no routine interval. It’s replaced if diagnostics confirm low oil pressure due to pump wear, a stuck relief valve, damage from debris, or after major internal engine failure. Always verify pressure with a mechanical gauge and check for restrictions, worn bearings, and oil grade issues first.

What oil should be used to protect the pump?
Use the oil grade and spec in the owner’s manual—commonly a high‑quality 5W‑30 meeting GM dexos2 or equivalent ACEA low‑SAPS diesel spec. Keep to 12‑month/15,000‑km services, or shorten intervals if towing, working in heat, or doing dusty, off‑road kilometres.
