2001 Daihatsu Terios Power Steering Fluid

For the 2001 Daihatsu Terios (first-gen J100/J102), power steering fluid is absolutely relevant. The factory workshop manual for the J100/J102 series (Steering — Power Steering) depicts a belt-driven hydraulic pump, reservoir and hoses, and specifies automatic transmission fluid (ATF) to DEXRON II or DEXRON III for the power steering system. The owner’s handbook maintenance section for this model includes a power steering fluid level check, and independent data providers (e.g., Autodata/Haynes) list it as a hydraulic power-assisted rack-and-pinion. So this model does not use electric power steering, it uses hydraulic assistance and needs the correct fluid.

On a 2001 Terios, the power steering fluid does the hard yakka of transmitting hydraulic pressure from the pump to the steering rack, making low-speed turning light and predictable. It also lubricates and cools the pump and valves. The right fluid (ATF DEXRON II/III) maintains the correct viscosity across temperatures, resists foaming, and keeps seals healthy, so the steering stays smooth, quiet and consistent on city streets or rough Kiwi and Aussie backroads.

For servicing, a quick visual level check at each oil service is smart. The reservoir has HOT/COLD marks, check on level ground, engine off, and top up only with ATF DEXRON II or III. If the fluid looks dark, smells burnt, or shows fine metallic sparkle, it’s time for a change. While many period manuals didn’t mandate a strict interval, a preventative refresh every 60,000–100,000 km (or 4–6 years) helps avoid pump whine and rack wear. After any steering component work, bleed air by turning the wheel lock-to-lock a few times with the engine running, keeping the reservoir topped and watching for bubbles to clear.

• Use only ATF DEXRON II or III, don’t mix with brake fluid or CVT fluid.
• Inspect hoses and clamps for weeps, even small leaks can aerate the system.
• A drain-and-fill typically uses around a litre, a full exchange may take 1–1.5 litres.
• Dispose of old fluid responsibly—treat it like used oil.

Done right, fresh fluid keeps the Terios steering light, quiet and reliable, reducing the chance of pump cavitation, cold-morning heaviness, or that annoying low-speed groan in the carpark.

Popular questions about 2001 Daihatsu Terios power steering fluid

What fluid does a 2001 Terios use?
It uses ATF to DEXRON II or DEXRON III spec in the power steering system. The reservoir cap and factory literature call this out. Stick with a reputable brand, the fluid is usually red. Avoid “universal” blends that don’t clearly state DEXRON II/III compatibility.

How often should it be changed?
Check level and condition every service. Many techs recommend replacing every 60,000–100,000 km or 4–6 years, or sooner if it’s dark, smells burnt, or after pump/rack work. Frequent short trips or dusty/off-road use can justify earlier changes.

How do you bleed the system after topping up or repair?
With the front wheels off the ground, engine running, slowly turn the wheel from lock to lock several times, pausing at each end. Keep the reservoir at the correct mark and watch for bubbles. Once the fluid runs clear and bubble-free and the steering is quiet, you’re good to go.
