2002 Daihatsu Gran Move Power-Steering Pump

Technical sources confirm the 2002 Daihatsu Gran Move (G303/G313, also known as Pyzar) is fitted with a hydraulic power‑steering pump. The Daihatsu Electronic Parts Catalogue (EPC) lists a belt‑driven “Pump Assy, Power Steering” for this model, and the Gran Move owner’s handbook includes routine checks for power‑steering fluid — both of which establish that a conventional hydraulic pump is used on this vehicle.

On the Gran Move, the power‑steering pump’s job is to supply pressurised fluid to the steering rack, so the wheel turns lightly at parking speeds and stays composed on the open road. It’s driven by the engine via a belt, circulating fluid through high‑pressure hoses, a control valve, and back to the reservoir. When it’s healthy, steering is smooth and predictable, when it’s tired, the wheel can feel heavy, the pump may whine, and you might spot fluid under the car or around the pump and hoses.

As part of regular servicing, it’s smart to check the fluid level and condition under the bonnet. Use the fluid type shown on the reservoir cap or in the owner’s manual — typically ATF meeting Dexron II or III for Daihatsu systems. Top up only if needed, and avoid mixing unknown fluids. If the fluid looks dark, smells burnt, or shows a silvery shimmer (fine metal), plan a flush and inspection.

Common tell‑tales that the pump’s on the way out include:

• Whining or groaning that rises with engine revs
• Heavier steering effort, especially at low speed
• Leaks from the pump shaft, reservoir, or hose crimps

When replacing the pump, also check the drive belt condition and tension, plus the high‑pressure and return hoses. After installation, bleed the system by filling the reservoir, starting the engine, and slowly turning the wheel from lock to lock several times without holding it hard against the stops. Keep an eye on the fluid level and bubbles, top up as required. A fresh filter screen (if fitted in the reservoir) and clean fluid go a long way to preserving the new unit.

With sensible checks each service — fluid, belt, and leaks — the Gran Move’s power‑steering pump typically gives years of faithful duty across Aussie and Kiwi roads.

Popular questions about the 2002 Daihatsu Gran Move power‑steering pump

What fluid should be used in the Gran Move’s power‑steering system?
Most Gran Move/Pyzar systems specify ATF meeting Dexron II or Dexron III, as indicated on the reservoir cap or in the owner’s handbook. If in doubt, match what’s specified for the vehicle — and don’t mix types. Using the correct fluid helps prevent pump noise, seal swelling, and premature wear.

How do you bleed the power‑steering after replacing the pump?
Fill the reservoir with the correct ATF, start the engine, and gently turn the steering wheel from lock to lock several times. Don’t hold it at full lock. Check for bubbles and drop in the fluid level, topping up as needed. Repeat until the fluid runs clear and quiet with no foaming and the assist feels even.

What are the signs the pump is failing?
Tell‑tales include a rising‑with‑revs whine, heavy or inconsistent steering, and visible leaks around the pump or hoses. Burnt‑smelling or glittery fluid is another red flag. If these show up, plan an inspection — catching it early can often save the rack and hoses from collateral damage.
