Parts for your 2000 Toyota Crown-Power steering pump

2000 Toyota Crown power-steering pump: purpose, care, and when to replace

Based on Toyota’s technical documentation and parts catalogues, the 2000 Toyota Crown (S170 series — common chassis codes JZS171/JZS173/GS171) is fitted with a belt-driven hydraulic power-steering pump. The Toyota Electronic Parts Catalog lists a “Pump Assy, Vane (Power Steering)” for these models — typical part numbers include 44320‑30220 and related supersessions — and the factory steering section for the S170 repair manual describes a conventional hydraulic-assist system rather than electric assist. That makes the power-steering pump directly relevant for anyone servicing or restoring a 2000 Crown.

On the Crown, the pump’s job is simple but critical: it pressurises fluid and sends it to the steering gear so the wheel feels light and predictable at parking speeds, yet stable on the motorway. Driven by the accessory belt, the vane-style pump relies on clean, correct-spec fluid and good hoses to stay quiet and leak-free.

For upkeep, a Crown owner benefits from a periodic fluid service. If the fluid’s gone dark, smells burnt, or shows metallic flecks, it’s time for a change — many workshops in Australia and New Zealand aim for a flush every 60,000–80,000 km or 4–5 years, or sooner if the car does lots of city driving. Use an approved ATF/PSF as marked on the reservoir cap or owner’s manual (many S170 cars accept Dexron III ATF, while some specify Toyota PSF). Keep the level at the “HOT”/“COLD” marks as applicable and watch for aeration (foam) after turns.

• Common warning signs: groaning or whining on cold start, heavier steering at idle, fluid weeping at the shaft seal or hose crimps, metal shimmer in the reservoir, or a belt chirp from pulley misalignment.
• Good workshop practice: inspect the drive belt for cracks and glazing, replace return hoses that have gone soft, renew banjo washers and O-rings if lines are disturbed, and bleed the system properly after any work (wheels off the ground, slow lock-to-lock with engine off, then on).
• When replacing: transfer the pulley and reservoir if required, flush the rack and lines to keep debris out of the new unit, and torque fittings to the repair manual spec. Running a pump dry, even briefly, can damage it — have fresh fluid ready before first start.

Whether choosing new genuine, quality reman, or aftermarket, pairing the pump with fresh fluid and tidy hoses usually restores that smooth, quiet steering feel the Crown is known for.

Popular questions

Does a 2000 Toyota Crown have a power-steering pump?

Yes. The S170-series Crown (circa 1999–2003) uses a hydraulic power-steering system with a belt-driven vane pump. Toyota’s Electronic Parts Catalog lists the pump for chassis like JZS171/JZS173/GS171, and the factory repair manual’s steering section details hydraulic assist rather than electric assist for these models.

What fluid should go in the Crown’s power steering, and how much?

Most S170 Crowns specify an ATF meeting Dexron II/III, while some markets note Toyota PSF. The correct type is printed on the reservoir cap or in the owner’s handbook. Capacity for a full drain/flush is typically around a litre (varies with the rack and how thoroughly it’s bled). Fill to the marks, bleed, recheck, and top up as needed.

What are the signs the pump needs replacing?

A loud whine that rises with engine speed, heavy or jerky steering at low rpm, visible leaks from the pump shaft or hose fittings, and glittery or burnt-smelling fluid are the usual tells. Before condemning the pump, check belt condition and tension, confirm the fluid type is correct, and inspect hoses. If noise or heaviness persists after a proper flush and belt check, the pump or steering rack may be worn.
