Parts for your 1998 Daihatsu Gran move-Power steering fluid

1998 Daihatsu Gran Move — Power Steering Fluid

Based on the Daihatsu Pyzar/Gran Move L5-series workshop manual (Steering section), the 1998 Owner’s Handbook, and Autodata service information, the 1998 Daihatsu Gran Move is fitted with a hydraulic power-assisted rack-and-pinion steering system driven by a belt-driven pump. It uses power steering fluid — specifically automatic transmission fluid meeting Dexron II or Dexron III — in its power steering circuit, so power-steering fluid is relevant for servicing this model.

Power steering fluid in the Gran Move does more than just make the wheel feel light. It transmits hydraulic pressure from the pump to the steering rack so the car turns with less effort at parking speeds, and it cushions, cools, and lubricates the pump and internal valves. In short, it’s the lifeblood of the hydraulic assist, keeping the steering smooth and the components protected under Aussie and Kiwi driving conditions.

Because fluid condition drives steering feel and component life, it’s smart to check the level and colour at each service. The translucent reservoir has MIN/MAX marks, the level should sit between them on a cold check. Fluid that’s clean and red is healthy. If it’s gone brown/black, smells burnt, looks milky (water ingress), or shows glittery flecks (wear), it’s time for a change. Stick to ATF Dexron II or Dexron III as specified by Daihatsu — don’t mix in universal or mineral “PSF” types not meeting Dexron spec.

While many period schedules list inspection only, fresh fluid every 2–3 years or about 40,000–60,000 km is good practice in hot or stop–start use. A proper exchange is done by disconnecting the return hose, catching old fluid, and feeding new fluid while the engine idles briefly, then bleeding. If you’re DIY’ing, keep the front wheels off the ground, turn lock-to-lock a few times with the engine off to purge air, top up, then recheck after a short drive.

Watch for telltales that need attention: a whining pump on cold mornings or when turning, heavier-than-normal steering, shudder at low speed, or dampness around hoses, the pump shaft seal, or the rack boots. Don’t overfill, keep fluid off belts, and replace tired clamps or O-rings during hose work. Disposing of used ATF at a recycling facility is the right call, and if the rack or pump is leaking, a specialist can pressure-test and repair before it gets pricey.

What type of power steering fluid does a 1998 Daihatsu Gran Move take?

Daihatsu specifies ATF meeting Dexron II or Dexron III for the Gran Move’s hydraulic power steering. That’s the same base type used in many automatics of the era. Avoid mixing with non-Dexron “universal” PS fluids or specialty mineral/synthetic CHF fluids, as they’re not intended for this system.

How often should the power steering fluid be changed?

Check the level and condition at every service. Even if not listed as a strict interval in some schedules, replacing the fluid about every 2–3 years or 40,000–60,000 km suits Australian and New Zealand conditions. Change it sooner if it’s dark, smells burnt, turns milky, or the steering gets noisy or heavy.

Where’s the power steering reservoir on a Gran Move?

It’s the small translucent plastic reservoir with a “Power Steering” cap, mounted high in the engine bay near the accessory drive. Follow the return hose from the pump and you’ll spot it easily. The exact side can vary with market layout, but it’s positioned for quick level checks and top-ups.
