2017 Holden Colorado Power-Steering Fluid

After checking technical sources specific to the MY17 RG Colorado — including the Holden RG Colorado Owner’s Handbook (MY17), GM Service Information (SI) for the 2017 Colorado/Trailblazer steering system, and the factory Service and Warranty booklet — it’s clear the 2017 Holden Colorado uses Electric Power Steering (EPS). That means there’s no hydraulic power-steering pump, no hoses, and no power-steering-fluid reservoir to check or top up.

Holden’s owner’s handbook for MY17 outlines an electric power-assisted rack-and-pinion system and doesn’t list a power-steering fluid under serviceable fluids. GM SI for the model year describes the EPS as a sealed, motor-driven unit on the steering rack with an electronic control module, it explicitly notes no periodic fluid maintenance. In short, power-steering fluid isn’t relevant to this vehicle because there’s no hydraulic system to service.

Why EPS? The electric motor provides assist without drawing power from the engine via a belt-driven pump. That brings a few wins: lighter steering at parking speeds, more stable assistance at highway pace, improved fuel efficiency (no parasitic drag from a pump), and fewer leak points. With no fluid or hoses, there’s also no chance of contaminated fluid causing pump or rack wear — and nothing to flush or replace on a service schedule.

What should owners pay attention to instead? While there’s no fluid to maintain, steering performance still benefits from good general upkeep:

• Battery and charging health — EPS relies on stable voltage, a weak battery or alternator can trigger heavy steering or warning lights.
• Correct tyre pressures and wheel alignment — both make the steering feel right and help the EPS work efficiently.
• Front-end checks — inspect rack boots, tie-rod ends and suspension bushings for wear or damage.
• Software and diagnostics — if a steering warning light appears, a scan with the correct GM tool (e.g., GDS2/Tech2) is the proper next step.

If someone’s recommending a “power-steering flush” for a 2017 Colorado, they’re likely thinking of earlier hydraulic systems or other models. For this MY17 setup, there’s simply no fluid to replace — just stick with regular servicing, keep the electrical system healthy, and sort any warning messages promptly.

FAQs

Does a 2017 Holden Colorado need power-steering fluid?
No. The MY17 RG Colorado runs Electric Power Steering, so there’s no hydraulic pump or reservoir. Holden’s owner’s handbook for MY17 and GM’s service information list no power-steering fluid or flush procedure for this vehicle.

Can power-steering fluid be topped up or flushed on this model?
No. There’s nothing to top up or flush because the system is electric, not hydraulic. If the steering feels odd, the fix isn’t “add fluid”, it’s to check battery/charging condition, tyres, alignment, and fault codes if a warning is shown.

What should be done if the steering feels heavy or a steering light appears?
Start with the basics: verify tyre pressures and the battery/alternator are healthy. If the warning persists, have the vehicle scanned with the correct GM diagnostic tool to pinpoint EPS-related faults before replacing parts.
