1996 Daihatsu Gran Move power‑steering fluid: what it is and how to look after it

Technical sources confirm the 1996 Daihatsu Gran Move (also sold as the Pyzar, chassis codes M100/M110) is fitted with a conventional hydraulic power steering system that relies on fluid. The Daihatsu Owner’s Manual and the Chassis & Body Service Manual for M1xx models specify a power‑steering reservoir and call for automatic transmission fluid (ATF) to the Dexron II standard, industry data providers such as Autodata also list the steering as hydraulic with ATF Dexron II/III fluid. Lubricant catalogues used in Australia and New Zealand (e.g., Penrite/Caltex/Castrol lube guides) echo the same requirement. That means power‑steering fluid is absolutely relevant for this vehicle.

On this Gran Move, the fluid does the hard yakka: it transmits hydraulic pressure from the pump to the steering rack, giving lighter, smoother steering at parking speeds and consistent assistance on the open road. Fresh, correct‑spec fluid also protects the pump, seals and rack from wear and corrosion.

For servicing, use ATF meeting Dexron II (or Dexron III) specification unless otherwise marked on the reservoir cap or service label. Avoid mixing with fluids that don’t state Dexron compatibility. A basic top‑up takes only a few hundred millilitres, a full exchange typically uses 1–2 litres to completely refresh the system.

Quick checks to work into regular services:

• Inspect the reservoir level on the HOT or COLD marks as indicated, with the car on level ground.
• Look at the fluid’s colour and smell: healthy ATF is red to amber and not burnt. Dark, gritty or foamy fluid needs attention.
• Scan for leaks around hoses, the pump, and the rack ends, dampness or red stains mean it’s time for new clamps or seals.

Replacement timing isn’t always specified by the manufacturer, but a sensible local rule is every 2–4 years or 40,000–60,000 kilometres, or sooner if the fluid discolours. For a driveway refresh, a partial exchange (siphon the reservoir, refill, run and repeat) is better than nothing. For a proper change, a workshop can disconnect the return hose and perform a controlled flush while maintaining reservoir level, then bleed the system by turning the wheel lock‑to‑lock with the front wheels off the ground. Always use clean funnels, don’t overfill, and wipe any spills off belts and pulleys.

Kept in good nick, the Gran Move’s hydraulic steering stays quiet, light and reliable, and the pump and rack will last far longer.

Popular questions

What power‑steering fluid does a 1996 Daihatsu Gran Move use?
It’s designed for ATF to the Dexron II specification, Dexron III is commonly accepted as a service replacement. Check the reservoir cap or the owner’s handbook for confirmation. Many universal power‑steering fluids are fine if they explicitly state Dexron II/III compatibility.

How often should the fluid be changed?
While some manuals don’t mandate a strict interval, changing it every 2–4 years or about 40,000–60,000 kilometres suits Australian and New Zealand conditions. Replace it sooner if it turns dark, smells burnt, or if the steering starts to whine.

What are the signs the fluid is low or failing?
Heavy steering at low speeds, a whining or groaning pump, foamy fluid in the reservoir, or red oily patches under the front of the car point to low level or deteriorated fluid. Topping up with the correct ATF and fixing any leaks usually restores proper feel and quiet operation.
