2000 Toyota Crown power-steering hose: what it does and how to look after it

Factory documentation and parts catalogues for the S170-series 2000 Toyota Crown (JZS171/173, GS171, UZS171) confirm it uses a hydraulic power steering system with dedicated hoses. Toyota’s Electronic Parts Catalogue (Steering > Power Steering Tube & Hose, group 44) lists a pressure feed hose (Toyota 44410‑xxxxx) and a return hose (44406‑xxxxx), and the Crown steering section in Toyota service manuals shows a belt-driven pump, reservoir, hoses and a rack-and-pinion. Those technical sources make it clear a power-steering hose is fitted and relevant on this model.

On the 2000 Toyota Crown, the power-steering hose does the heavy lifting for the hydraulic assist. The high-pressure hose carries fluid from the engine-driven pump to the steering rack, while the low-pressure return hose brings it back to the reservoir. Together they allow light, smooth steering feel at parking speeds and stable assist at motorway pace, keeping the big sedan easy to manoeuvre.

Two decades on, heat, age and engine-bay movement can harden rubber, loosen crimps and weep at banjo fittings. Tell-tale signs include heavier steering, a whine from the pump, reddish fluid spots on the driveway, a burnt-oil smell if fluid mists onto the exhaust, or foamy fluid in the reservoir. Because a leaking hose can lower fluid level and cook the pump, it’s a small part that protects a much bigger bill.

• Inspection: at each service (around every 10,000–15,000 km or annually), check the pressure hose for sweating, cracks, soft spots or chafe marks, and the return hose for hardness or swelling. Look over clamps, brackets and the heat shield where fitted.
• Fluid care: keep the reservoir at the correct mark with the fluid specified on the cap/manual (most S170 Crowns use ATF Dexron II/III). Consider a flush every 60,000–80,000 km or 4–5 years to maintain colour and lubricity.
• Replacement: use quality OEM or equivalent hoses rated for power steering pressures, new sealing washers/O-rings, and refit brackets so the hose can’t rub. Torque fittings to factory spec and bleed the system properly.

After hose replacement, bleed by lifting the front wheels, turning lock-to-lock slowly with the engine off, topping fluid, then starting and repeating until bubbles clear. If the level keeps dropping, don’t keep topping up—find the leak promptly. Protect nearby components (like the alternator) from fluid, and dispose of old ATF responsibly. Look after the hoses and the Crown’s steering stays light, quiet and reliable.

Popular questions

What power steering fluid does a 2000 Toyota Crown use?
Most S170-series Crowns specify ATF Dexron II or Dexron III in the power steering system. Always confirm on the reservoir cap or the steering section of the service manual for the exact variant. Avoid mixing fluid types and stick with a known brand for consistent performance, especially in hot Australian and New Zealand conditions.

How often should the power-steering hose be replaced?
There’s no fixed interval. Hoses are replaced on condition—cracks, sweating at crimps, soft spots, or active leaks. Given age, many original hoses are due any time after 15–25 years. Regular inspections at service time are the best way to catch issues early and protect the pump and rack.

Can a leaking power-steering hose be repaired?
High-pressure sections generally shouldn’t be patched, they’re designed to handle significant pressure and are best replaced. A reputable hose specialist can often remake a hose using the original fittings and new high-pressure line to the correct rating. Stop-leak additives aren’t recommended for long-term use in these systems.
