1997 Daihatsu Terios Power Steering Hose — What It Does and How to Look After It

Relevant technical sources confirm that the 1997 Daihatsu Terios (J100 series) uses a hydraulic power-assisted steering system with both a high-pressure feed hose and a low-pressure return hose. These sources include: Daihatsu Terios J100 Series Workshop Manual (Steering – Power Steering section, 1997), the Daihatsu Electronic Parts Catalogue (J100G/J102, Steering group, listing power steering pressure and return hoses), and Autodata Technical Data & Repair for the period covering 1997 models (noting hydraulic PAS and ATF-type fluid). On that basis, a power-steering hose is absolutely fitted and relevant to the 1997 Terios.

On a 1997 Terios, the power steering hose pair is the lifeline of the hydraulic assist. The high-pressure hose carries pump output to the steering gear, while the return hose feeds fluid back to the reservoir. That closed loop helps deliver light, predictable steering at low speeds and steady feel on the open road. When the hoses are in good nick, the pump doesn’t have to work as hard, the rack stays happy, and the wheel turns feel nicely weighted.

As part of routine servicing, it’s smart for owners to have the hoses checked for sweating, cracking, hardening, or chafe marks—especially where the line clips to the body or passes near heat. Any sign of red or amber ATF under the bonnet or on the driveway points to a leak. Left alone, a tiny weep can turn into heavy steering, pump noise, or even a cooked pump. The Terios typically specifies ATF (Dexron II/III) for the power steering, so topping up with the right fluid matters. Don’t mix fluids, and if contamination is suspected, organise a flush.

• At each service: Inspect hose outer sheathing, clamps, and banjo/flare connections. Check for kinks and rubbing.
• If replacing: Use quality OEM-equivalent pressure hose and fresh sealing washers/O-rings as specified by the workshop manual.
• After any hose work: Refill with the correct ATF, then bleed by turning the wheel lock-to-lock slowly with the engine running, avoiding holding at full lock. Top up and recheck for foaming.

Because the earliest Terios examples are now well past two decades old, age-related hose hardening is common. Many owners elect to replace both the pressure and the return hose at the first sign of deterioration to avoid repeat labour and to protect the pump and rack. Keeping the auxiliary belt tension correct and the reservoir filter (if fitted) clean will also help the system live a long, quiet life.

Popular questions

What power steering fluid does a 1997 Daihatsu Terios use?

The factory documentation for the J100 series specifies an ATF-type fluid, commonly Dexron II or Dexron III. Sticking with a quality ATF that meets Dexron II/III specs keeps seal compatibility and steering feel where it should be. Avoid mixing fluid types, if unsure what’s in there, have the system flushed.

How do you bleed the Terios power steering after changing a hose?

Fill the reservoir with the correct ATF. With the front wheels off the ground if possible, start the engine and slowly turn the wheel from lock to lock several times without holding it on the stops. Keep the fluid topped up and watch for bubbles. Once the fluid runs clear with no foam and assist feels normal, lower the vehicle and recheck the level.

What are the signs a power steering hose needs replacing?

Typical signs include a burnt-ATF smell, red/amber fluid drips, damp hose sections, heavy or jerky steering at low speeds, and pump whine. Any cracking, swelling, or chafe on the hose outer cover is a cue to replace before it lets go under pressure.
