1999 Toyota Crown Power‑Steering Hose — What It Does, When To Replace, and How To Look After It

Technical sources confirm the 1999 Toyota Crown (S170 series: JZS17x/GS171 families with 1G‑FE, 1JZ‑FSE and 2JZ‑FSE engines) uses a hydraulic power steering system with both a high‑pressure feed hose and a low‑pressure return hose. The Toyota Electronic Parts Catalogue lists “HOSE, PRESSURE FEED” and “HOSE, RETURN” for these models, and the Crown S170 steering section in the factory repair manual details hose inspection, pressure testing and replacement procedures. So yes, a power‑steering hose is fitted and absolutely relevant to the 1999 Toyota Crown.

On this Crown, the power‑steering hose pair carries fluid between the belt‑driven pump, the steering rack and the reservoir. The high‑pressure hose handles serious hydraulic pressure, feeding the rack so steering stays light at parking speeds, while the return hose sends fluid back to the reservoir and helps dampen pulses. When these hoses harden, crack, or weep at crimps, owners will often notice a groan from under the bonnet, slight steering heaviness, or red/amber fluid spots on the driveway.

For servicing, it pays to check the hoses at every service interval: look for sweating around crimp joints, soft spots, chafe marks where a hose may rub a bracket, and any signs of fluid misting near the pump or rack. A quick wipe, then a road test and re‑check, will show fresh seepage clearly. If the pressure hose shows any weeping or swelling, replacement is the smart move—leaving it can risk a sudden loss of assist and a messy clean‑up.

• Use quality OEM or reputable aftermarket hoses designed for the S170 Crown. Ensure correct banjo fittings and line routing.
• Replace sealing washers on banjo bolts, secure heat shields and clips, and keep hoses clear of the exhaust.
• Top up with the specified fluid (Toyota PSF or Dexron II/III ATF as marked on the reservoir cap), then bleed by turning lock‑to‑lock with the front wheels off the ground. Don’t let the pump run dry.
• After bleeding, check for aeration (foam), re‑torque fittings to spec per the workshop manual, and re‑inspect over the next few drives.

Many Crowns run well past 200,000 km before hoses need attention, but age, heat and fluid contamination accelerate wear. If the steering’s noisy cold, the wheel feels heavier than usual, or the reservoir level keeps dropping, the hose set is a prime suspect. A tidy hose refresh, fresh fluid and correct bleeding make the steering quiet, consistent and confidence‑inspiring.

Popular questions about 1999 Toyota Crown power‑steering hoses

What fluid should a 1999 Toyota Crown use in the power steering?
Most S170 Crowns specify Toyota Power Steering Fluid or an ATF meeting Dexron II/III. The reservoir cap or owner’s handbook will state the correct type. Mixing different fluids isn’t ideal—stick to one spec and, if changing types, perform a full flush to avoid additive clashes.

How do you bleed the Crown’s power steering after hose replacement?
With the front wheels off the ground, fill to the “COLD” mark, then turn the wheel slowly from lock to lock 10–15 times with the engine off. Top up, then start the engine and repeat gently, watching for bubbles. Keep the fluid topped up, avoid overfilling, and recheck for leaks after a short drive.

How can someone tell the high‑pressure hose is failing?
Tell‑tales include a groan when turning at low speeds, a damp crimp joint, soft or swollen rubber near the fittings, and drops in reservoir level. Any red/amber fluid under the front of the car or spray patterns on nearby components points to a leak that needs prompt attention.
