1998 Toyota Caldina Power-Steering Hose — What it does and how to look after it

Yes, a power‑steering hose is absolutely relevant and used on the 1998 Toyota Caldina. Toyota’s Electronic Parts Catalogue (EPC) for Caldina ST21# series (1997–2002) lists a “Hose, Pressure Feed” and a “Hose, Return” in the Steering group, and the factory Repair Manual for ST210/ST215 covers removal, installation and bleeding procedures for the hydraulic power‑steering system. Those technical sources confirm the 1998 Caldina runs a conventional hydraulic setup, with hoses linking the pump on the engine to the steering rack.

On this model, the power‑steering hose does two key jobs: the high‑pressure line carries pressurised fluid from the pump to the rack to provide steering assist, while the low‑pressure return hose brings fluid back to the reservoir. Together they let the pump deliver smooth, light steering feel at parking speeds and stable assist on the open road. Toyota specifies ATF (commonly Dexron II/III) as the working fluid, so the hose must handle both heat and pressure without weeping or swelling.

Because hoses age with heat, vibration and fluid exposure, they deserve a quick look at every service. Under the bonnet, check for dampness around banjo fittings and flare nuts, cracked rubber sections, chafe marks where a hose may touch a bracket, and any aeration or dark, burnt‑smelling fluid in the reservoir. A light groan at full lock, heavy steering when cold, or pink/red droplets under the front of the car are all hints the hose or its seals are due.

• Visible leaks or “sweating” at hose crimps or banjo joints
• Rubber hardening, cracking, or swelling
• Whine or groan from the pump, especially on turns
• Foamy or very dark fluid in the reservoir

When replacing a Caldina power‑steering hose, use quality OEM‑equivalent parts, new sealing washers and O‑rings, and a flare‑nut spanner to avoid rounding fittings. Keep everything clean, cap open ports, and route the hose exactly as per the original to prevent rubbing. Tighten fittings to the repair manual specification, refill with the correct ATF, then bleed by turning the wheel lock‑to‑lock with the engine off, topping up, and repeating with the engine running until bubbles are gone. Dispose of old fluid responsibly.

For ongoing care, refresh the fluid every 2–3 years or around 40,000–50,000 km, and shorten inspection intervals if the car sees hot climates, towing, or (for GT‑T owners) turbocharged under‑bonnet heat. Catching a minor seep early protects the pump and rack and keeps steering light and confidence‑inspiring.

Popular questions about 1998 Toyota Caldina power‑steering hoses

What fluid should go in a 1998 Caldina’s power steering?
Toyota specifies automatic transmission fluid (ATF), typically Dexron II or Dexron III, for the Caldina’s hydraulic power‑steering system. Don’t mix types, stick with one quality ATF and keep the reservoir at the correct mark. A drain‑and‑fill usually takes around a litre, while a full flush can take more.

Is it safe to drive with a leaking power‑steering hose?
It’s not a great idea. A small seep can quickly turn into a big leak, which can starve the pump, cause heavy steering, and contaminate belts and other components. If the fluid runs low you can lose assist without warning and risk damaging the pump and rack. Top up if you must move the car and have the hose repaired promptly.

How often should the hose be checked or replaced?
Give the hoses a quick visual check at every service and a closer look every 10,000–15,000 km. There’s no fixed replacement age, but many original hoses start to harden and seep after long years of heat cycles. Replace at the first sign of leakage, cracking, or swelling, and always fit new sealing washers.
