1999 Daihatsu Gran Move — Power-Steering Fluid

Based on technical references including the Daihatsu Pyzar/Gran Move Owner’s Manual (1997–2000), the Daihatsu G303/G313 Workshop Manual (Steering section), and Autodata specifications used by AU/NZ workshops, the 1999 Daihatsu Gran Move is fitted with a conventional hydraulic power-steering system. It uses automatic transmission fluid (ATF) to specification Dexron II or Dexron III as its power-steering fluid. So yes—power-steering-fluid is relevant and required on this model.

This Gran Move’s hydraulic power steering relies on fluid to do the heavy lifting. The pump pressurises the ATF, which then helps move the steering rack with far less effort at the wheel. The fluid also lubricates the pump and rack, controls heat, dampens noise, and protects seals and internal components from wear and corrosion. Keeping the fluid clean and at the right level makes the steering feel light, consistent, and quiet—just how owners want it around town and on the open road.

While Daihatsu documentation focuses on regular inspections rather than a strict change interval, many Australian and New Zealand workshops treat power-steering fluid as a service item. A sensible preventative schedule is to replace the fluid every 2–3 years or roughly 40,000–60,000 kilometres, or sooner if it’s discoloured, smells burnt, or the system’s been opened for repair. Always use ATF that meets Dexron II or Dexron III—don’t mix with other fluid types.

• Check the level on level ground with the engine off (or as directed on the reservoir cap). Top up to the COLD or HOT mark as applicable.
• Healthy fluid is typically a clear red. If it’s very dark, gritty, or foamy, plan a change and a leak check.
• After a refill, bleed air by turning the steering from lock to lock several times with the engine running, then recheck the level.

Common signs it’s time for attention include heavier-than-normal steering, groaning or whining from the pump, and fluid around hose joints, the pump, or rack boots. Inspect the drive belt for condition and tension too, a slipping belt can mimic pump issues. When topping up, keep everything clean—wipe around the cap before opening and avoid overfilling. If leaks are present, sort those first so fresh fluid stays fresh.

Popular questions about 1999 Daihatsu Gran Move power-steering fluid

What power-steering fluid does a 1999 Daihatsu Gran Move use?
It uses ATF meeting Dexron II or Dexron III. Many bottles labelled “power steering fluid” are fine only if they state Dexron II/III compatibility. Stick to a reputable ATF and avoid mixing with other types.

How often should the fluid be changed?
Inspect at each service. As preventative maintenance in AU/NZ conditions, many workshops recommend replacing it every 2–3 years or 40,000–60,000 km, or sooner if the fluid is dark, burnt, or the system has had repairs.

Where’s the power-steering reservoir located?
Under the bonnet, typically on the right-hand side of the engine bay (driver’s side on RHD vehicles). It’s a small, translucent reservoir with a cap/dipstick, feeding the belt-driven power-steering pump via a hose.
