2000 Daihatsu Gran Move power-steering pump: purpose, servicing and replacement

Technical sources including Daihatsu factory service literature for the late-1990s to 2002 Gran Move/Pyzar and OEM parts catalogues show this model uses a hydraulic power-steering system with a belt-driven vane pump. Australian and New Zealand–delivered 2000 vehicles list power steering as standard, making the power-steering pump a relevant, fitted component.

The pump’s job is simple but vital: it pressurises power-steering fluid and feeds the steering rack so the wheel turns smoothly at parking speeds and stays steady on the highway. When the pump starts to tire, drivers often notice a whine on lock, heavier steering, or damp patches around hoses and the pump body. Left too long, contaminated or low fluid can take out the pump and the rack, so it pays to give it a bit of love at service time.

As part of routine servicing on a 2000 Daihatsu Gran Move, it’s smart to:

• Check fluid level and colour at every service, top up only with the specified ATF (commonly Dexron II/III—confirm on the reservoir cap or owner’s manual).
• Inspect the drive belt for cracks, glazing, or slack, and replace if worn.
• Look over hoses and clamps for seepage, renew O-rings if any fittings have been disturbed.
• Flush and refill the system every 60,000–80,000 km or 4 years, especially if fluid is dark or smells burnt.

When replacement is on the cards—whether due to noise, leaks, or low pressure—swapping the pump is a straightforward driveway job for competent DIYers, though many will prefer a workshop. A quality new or professionally remanufactured unit is recommended, bargain-basement options can be noisy or short-lived. Expect about 1–2 hours’ labour in typical workshop conditions.

1. Safely raise the front, disconnect the battery, and drain/collect old fluid from the reservoir.
2. Slip off the drive belt, cap hoses to prevent mess, and unbolt the pump.
3. Transfer brackets as needed, fit new O-rings, install the replacement pump, and refit the belt with correct tension.
4. Refill with the correct fluid and bleed: with wheels off the ground, turn lock-to-lock slowly several times with the engine idling, topping up until bubbles clear.
5. Check for leaks, wipe everything clean, and road test. Recheck level after a day or two.

A tidy, leak-free pump keeps steering light, protects the rack, and makes daily driving that bit easier. Under the bonnet checks and fresh fluid go a long way to ensuring this little Daihatsu keeps turning happily for years.

Popular questions about 2000 Daihatsu Gran Move power-steering pumps

What fluid should be used in the Gran Move’s power steering?

Most 2000 Gran Move models specify ATF meeting Dexron II or Dexron III for the power-steering system. Always double-check the reservoir cap and the owner’s book. Don’t mix fluid types, and if uncertain, do a complete flush before refilling with the correct ATF.

How is the system bled after fitting a new pump?

Fill the reservoir to the max line, lift the front wheels, and with the engine idling turn the steering slowly from lock to lock 10–15 times. Keep topping up so the level never drops below the filter screen. Wait a few minutes for bubbles to disperse, repeat if needed, then road test and recheck the level. Foam or groaning usually means more bleeding is required or there’s an air leak on the suction side.

How can someone tell if the pump or just the belt is the problem?

A slipping or cracked belt can squeal briefly on start-up or under load and may leave rubber dust. A failing pump tends to whine continuously, especially near full lock, and may show leaks around the shaft or fittings. Correct belt tension first, if noise persists, inspect fluid for glitter (metal) and check pressure/flow to confirm pump health.
