Parts for your 2014 Holden Colorado-Starter motor

2014 Holden Colorado starter-motor – what it does and how to look after it

Based on the Holden RG Colorado Service Manual (2012–2016), GM Global Service Information (SI) and mainstream starter-motor references from ACDelco and Bosch, the 2014 Holden Colorado absolutely uses a conventional 12‑volt starter motor mounted at the transmission bellhousing. It’s a critical part of the diesel and petrol variants, cranking the engine to life every time the key is turned.

The starter-motor’s job is simple but tough: the solenoid shoves the pinion into the flywheel ring gear, and a high‑current electric motor spins the engine fast enough for fuel and spark (or diesel injection) to take over. On the RG Colorado, reliability is generally solid, but like any hardworking electric motor living near heat, mud and road grime, it benefits from sensible checks during servicing.

For routine servicing of a 2014 Colorado, it’s smart to: keep the battery healthy and correctly rated, clean and tighten battery terminals and the engine earth strap, inspect the starter’s main cable and trigger wire for corrosion or chafing, and listen for any change in cranking speed or odd noises after off‑road or water crossings. If the ute does a lot of towing or hot running, heat‑soak can make a tired starter show its age.

• Common red flags: slow or laboured cranking, a single click with no crank, a rapid clicking from low voltage, grinding on engagement, or intermittent “no‑start” even with good dash lights.
• Quick checks before blaming the starter: load‑test the battery, confirm alternator charge rate, and perform a voltage‑drop test on the positive and earth paths to the starter.

If replacement is needed, go with OE‑quality new or remanufactured units from reputable makers. Verify the correct unit by VIN, as there are variations across engines and build dates. Replacement isn’t typically a DIY job on the driveway unless they’re confident with electrics and safe jacking. Key points include safely disconnecting the battery (negative first), noting any heat shields or spacers, refitting with the correct torque per the Holden workshop spec, and protecting connections from moisture. After fitting, confirm cranking current draw and charge rate so the new unit isn’t masking an underlying battery or wiring issue.

There’s no fixed replacement interval for a starter-motor on the RG Colorado. Treat it as condition‑based: if it cranks strong and tests clean, keep driving. If symptoms pop up, testing and, if needed, a quality replacement will keep the ute starting first go.

Popular questions about 2014 Holden Colorado starter-motor

Where is the starter-motor located on a 2014 Colorado?
It’s bolted low on the engine at the bellhousing area, accessible from underneath. Expect heat shielding and tight clearances, most inspections and replacements are done from below with the vehicle safely supported.

Can a weak battery feel like a bad starter?
Yes. A tired or undersized battery can cause slow cranking or a click with no crank, just like a failing starter. Always load‑test the battery and check voltage drop across cables before calling the starter faulty.

Does the 2014 Colorado use stop/start instead of a normal starter?
No. Australian and New Zealand‑market 2014 RG Colorados use a conventional 12‑V starter-motor. There’s no idle stop/start system on that model year, so the starter remains the primary way the engine is cranked.
