1999 Daihatsu Gran Move power-steering hose: what it does and how to look after it

Yes, the 1999 Daihatsu Gran Move is fitted with power-steering hoses. Technical references that confirm this include the Daihatsu Gran Move/Pyzar chassis workshop manual (steering section), the Daihatsu Electronic Parts Catalogue for G3-series models (G311/G313), and aftermarket parts catalogues from major suppliers that list both a high-pressure power-steering hose and a low-pressure return hose for the 1999 model. These sources describe a belt-driven hydraulic pump feeding the rack via a crimped high-pressure hose, with a return hose taking fluid back to the reservoir—classic hydraulic power steering, not electric.

On this Gran Move, the power-steering hose set does two big jobs: the pressure hose carries high-pressure fluid from the pump to the steering rack to give that easy, one-finger turn at parking speeds, while the return hose brings fluid back to the reservoir to cool, de-aerate and recirculate. Together they manage pressure, flow and heat, and their flexibility isolates pump and engine vibration from the rack.

If the hoses age, crack, or the crimps weep, the system loses pressure and fluid. Common clues are heavier-than-normal steering, a pump whine when turning, reddish ATF/PSF spotting on the subframe, or a burnt fluid smell. Under the bonnet, look for dampness around banjo fittings, swollen hose sections near heat, and perished rubber at clamps.

Replacement is straightforward if done carefully. Use a quality, vehicle-specific high‑pressure hose (don’t substitute generic fuel hose) and renew copper washers/O‑rings at the banjos and flare joints. Torque the fittings to spec, route the hose away from exhaust heat, and replace any tired return hose with oil‑rated line. Refill with the fluid specified in the owner’s manual (commonly Dexron II/III ATF for this model, but always check the cap/manual), then bleed by turning lock‑to‑lock with the front wheels off the ground and the engine idling. Top up to the correct level and recheck for aeration and leaks after a short drive.

• Quick service tip: inspect hose condition and clamps every 10,000 km or at each service, keep the drive belt in good nick, and avoid holding full lock for more than a few seconds to reduce heat and pressure spikes.

Popular questions

What fluid does a 1999 Daihatsu Gran Move use for power steering?
Most markets specify an ATF such as Dexron II or III for the Gran Move’s power steering. Always confirm on the reservoir cap and in the owner’s manual. Using the correct spec helps protect the pump, rack seals and hoses, and keeps assist feel consistent.

How can someone tell if the power-steering hose is failing?
Look for wetness around hose crimps or banjo bolts, reddish fluid drips under the front, heavy or jerky steering at low speed, and a groaning or whining noise on turn. Also check for cracked or swollen rubber and any rubbing points where the hose could chafe.

Is it safe to drive with a leaking power-steering hose?
It’s not recommended. A small seep can quickly turn into a major leak, risking sudden loss of assist and damage to the pump from running low on fluid. If a leak’s spotted, top up to get home if absolutely necessary and book the repair promptly.
