1998 Daihatsu Gran Move power-steering-pump

Based on technical references — including the Daihatsu Pyzar/Gran Move Workshop Manual (Chassis and Steering sections, 1997–2002), the Daihatsu Electronic Parts Catalogue for G301/G303 chassis, and aftermarket catalogues from Gates and Dayco that list a dedicated power-steering pump drive belt for this model — the 1998 Daihatsu Gran Move is fitted with a belt-driven hydraulic power-steering pump.

The power-steering pump on a 1998 Gran Move does the heavy lifting, circulating hydraulic fluid to help turn the wheels with minimal effort. It’s there to make city parking a doddle and long trips less tiring, all while keeping steering feel consistent. Driven off the engine via a multi-rib belt, the pump pressurises fluid that travels through hoses to the steering rack, then back to the reservoir for another lap.

As part of routine servicing, it’s smart to check the fluid level and condition every service interval. Use the correct ATF (commonly Dexron III, confirm on the reservoir cap or service manual), and don’t mix fluid types. If the fluid looks dark, smells burnt, or shows metallic sparkle, plan a flush and inspect the pump and hoses. A proper bleed after any work — wheels off the ground, turn lock-to-lock with the engine off, top up, then repeat with the engine running — helps clear air and keeps the assist smooth and quiet.

When it’s time for a replacement, go beyond just the pump. Renew the drive belt if it’s glazed or cracked, fit new O-rings and sealing washers on high-pressure lines, and check the reservoir filter (if fitted). Pulley alignment matters — a misaligned or over-tightened belt will make the pump whine and wear out quicker. After installation, verify there are no leaks under load and recheck the fluid level once the system has settled.

• Common symptoms of a tired pump: heavy steering at idle, groaning or whining on turns, red ATF spots under the car, or a foamy reservoir.
• Good practice: flush the system whenever the pump or a major hose is replaced, and keep an eye on the high-pressure hose for swelling or seepage.
• Safety tip: if steering suddenly goes heavy, avoid forcing the wheel at full lock — that spikes pressure and can finish off a weak pump or hose.

Popular questions about 1998 Daihatsu Gran Move power-steering-pump

What fluid should be used in the Gran Move’s power steering?
Most Australian and New Zealand–delivered Gran Moves specify ATF meeting Dexron III for the power steering. Always double-check the reservoir cap and the workshop manual. Stick to one spec — mixing fluids can cause seal swell or aeration, leading to noise and reduced assist.

How long does a power-steering pump typically last?
With clean fluid and a healthy belt, many pumps see well over 150,000 km. Heat, old fluid, and a slipping belt shorten their life. Early warnings include a rising whine, heavier steering when parking, and fine leaks around the front seal or hose unions.

Is it safe to drive with a failing power-steering pump?
It’s not ideal. Steering effort can spike, especially at low speed, which isn’t great in traffic or tight parks. If the pump is shedding metal or the fluid’s contaminated, you risk damaging the steering rack. Best move: park it, fix the leak or pump, flush the system, and get back on the road with full assist.
