Parts for your 1997 Daihatsu Gran move-Power steering hose

1997 Daihatsu Gran Move power-steering hose — purpose, care, and when to replace

Referencing technical sources including the Daihatsu electronic parts catalogue for the G3-series Gran Move/Pyzar (circa 1996–2002), the factory steering section in the service manual, and common aftermarket catalogues from Gates and Mackay Rubber, the 1997 Daihatsu Gran Move is fitted with a hydraulic power-steering system. That setup uses both a high-pressure power-steering hose and a return hose running between the pump and the steering rack, so a power-steering hose is absolutely relevant on this model.

On a 1997 Daihatsu Gran Move, the power-steering hose does the heavy lifting for the hydraulic assistance. The high-pressure hose carries fluid from the belt-driven pump to the rack at serious pressure, while the return hose sends fluid back to the reservoir. Together, they let the driver steer smoothly at parking speeds without arm-wrestling the wheel, and they help maintain a consistent steering feel on open roads.

Because these hoses live near engine heat and see constant pressure pulses, age hardens the rubber and can fatigue the crimps. Tell-tales include a light film of fluid (“sweating”), damp spots at the crimped ends, red or amber drips under the front of the car, a whining pump, or heavier-than-normal steering. Leaving it will risk pump damage and messy leaks over the driveway.

As part of regular servicing, it’s smart to:

• Inspect the hose outer sheathing and crimps every 10,000–15,000 km.
• Check for weeps under the banjo fittings and at the rack connections.
• Top up with the specified ATF (commonly Dexron II/III on this model—confirm on the reservoir cap or service manual).
• Refresh fluid every 2–3 years to keep seals happy.

If replacement’s on the cards, go for an OE-equivalent pressure hose rated for hydraulic steering. Replace sealing washers/O-rings with new, keep everything surgically clean, and avoid twisting the new hose during fitment. After installation, bleed the system properly:

1. Front wheels off the ground, engine off: turn lock-to-lock slowly 10–15 times.
2. Start the engine and repeat, topping the reservoir as bubbles clear.
3. Set the car down, recheck fluid level, and inspect for leaks after a short drive.

Routing matters too—keep the hose away from exhaust heat and secure it with the correct clips to prevent chafe. With the right hose and a proper bleed, the Gran Move’s steering stays light, quiet, and drama-free.

FAQs

What fluid should be used in the 1997 Daihatsu Gran Move’s power steering?
Most 1997 Gran Move cars specify ATF such as Dexron II or Dexron III for the power-steering system. The reservoir cap or the factory service manual will confirm the exact spec. Mixing fluids isn’t recommended—stick to one type and keep it clean.

How long do power-steering hoses typically last on a Gran Move?
In local Aussie and NZ conditions, 15–25 years of service is common, but age, heat, and prior leaks are the deciders. If the hose shows cracking, swelling, or sweating at the crimps—or if the pump starts to whine—plan a replacement rather than waiting for a blowout.

Can a leaking power-steering hose damage the pump?
Yes. Low fluid causes aeration and starvation, which overheats and scores the pump. If there’s a leak, top up with the correct ATF, avoid long drives, and sort the hose promptly to protect the pump and rack.
