1997 Daihatsu Terios Power-Steering Pump — Fitment, Purpose, and Service Tips

Technical sources indicate the 1997 Daihatsu Terios (J100 series, HC‑EJ 1.3 petrol) is equipped with a belt‑driven hydraulic power‑steering pump from factory. This isn’t an electric system, it uses a conventional vane‑type pump to supply hydraulic assist to the steering rack.

• Daihatsu Terios J100/J102 Series workshop/service manual: Power Steering section describes a hydraulic system with a belt‑driven pump, reservoir, and high‑pressure/return lines.
• Daihatsu Electronic Parts Catalogue (EPC) for J100G lists “Pump Assy, Power Steering” with associated hoses, reservoir, and brackets for the HC‑EJ engine.
• Aftermarket catalogues (e.g., Gates/Dayco) show the accessory belt routing including the P/S pump for 1997–2005 Terios 1.3 models.

On a 1997 Terios, the power‑steering pump does the heavy lifting so steering stays light at parking speeds and consistent on rough Kiwi and Aussie roads. Driven by the crankshaft belt, it pressurises fluid for the steering rack, giving a tidy balance of assist without dulling road feel. If the pump’s not happy, drivers often notice a whine on cold starts, heavier steering at low speed, foamy fluid in the reservoir, or damp patches around the pump’s front seal or pressure hose.

For regular servicing, it’s worth treating the pump and fluid like any other consumable support system. Check fluid level and condition at each service, the Terios typically specifies ATF meeting Dexron II/III. If it’s dark, smells burnt, or looks glittery, plan a fluid exchange and inspect for source contamination. Refresh the drive belt when cracked or glazed, and set tension per the workshop manual after any adjustment. A simple bleed helps banish aeration: wheels off the ground, engine off, turn lock‑to‑lock slowly, top up, then repeat with the engine idling—avoiding holding full lock for more than a few seconds.

When replacing the pump, disconnect the battery, drain the reservoir, slacken the belt, and cap lines to keep grit out. Always fit new O‑rings and sealing washers, clean out the reservoir, and consider replacing the belt at the same time. Torque fittings to the manual’s specs, prime the pump with fresh fluid, and bleed thoroughly. If metal fines are found, flush the rack and lines to protect the new unit. A quality reman or new pump, correct fluid, and a tidy belt go a long way to keeping this compact SUV’s steering sweet.

Popular questions about 1997 Daihatsu Terios power‑steering pumps

What fluid does the 1997 Terios use in the power steering?
The system uses ATF that meets Dexron II or Dexron III. Many owners stick with a reputable Dexron III ATF for availability. Mixing different fluid types isn’t recommended—if switching brands or types, do a proper drain and refill or a staged exchange to keep the system happy.

How can someone tell if the power‑steering pump is failing?
Common signs include a groaning or whining noise that tracks engine speed, heavier steering at low speed, aerated or discoloured fluid, and leaks at the pump shaft or pressure hose banjo. If noise improves after topping up, there’s likely a leak, if it worsens when turning, the pump or belt may be the culprit.

Is the 1997 Terios electric power steering?
No. The 1997 model runs a hydraulic setup with a belt‑driven pump. That’s why belt condition, fluid quality, and correct bleeding make such a difference to steering feel.
