2000 Holden Commodore power-steering hose — what it does and how to look after it
Yes, a power‑steering hose is absolutely fitted to the 2000 Holden Commodore. Technical sources including the Holden VT–VX Factory Workshop Manual, the GMH Electronic Parts Catalogue for VT/VX, and aftermarket catalogues from ACDelco and Gates all specify a hydraulic rack‑and‑pinion system with a belt‑driven pump, a high‑pressure hose from the pump to the steering rack, and a low‑pressure return hose back to the reservoir. That applies to both the 3.8‑litre V6 (VT II/VX) and the 5.7‑litre V8 (VX) models.
On a 2000 Commodore, the power‑steering hose’s job is to safely carry ATF (Dexron III spec) between the pump and the rack. The high‑pressure side sees serious pressure every time the wheel is turned, while the return hose feeds fluid back to the reservoir. Together they let the pump do the heavy lifting, so steering stays light at parking speeds and consistent on the open road. Correct hose routing and intact mounting clips keep the lines clear of heat and rubbing, which is especially important on V8s near the exhaust.
As part of regular servicing, the hose assembly deserves a quick once‑over. Look for wetness at crimp joints, perished rubber, cracks, or chafe marks. A low reservoir, red fluid drips, pump whine, or a heavy steering feel are all clues the system’s weeping or sucking air. Fresh Dexron III and a periodic flush help the pump and rack last longer, and keep the hose internals healthier.
- Common reasons to replace: visible leaks, swollen or cracked hose, collapsed return line, fitting corrosion, or persistent aeration/whine.
- Use quality hose assemblies and new O‑rings/sealing washers. Tighten to the workshop manual spec and avoid over‑torquing flare fittings.
- Route exactly as per factory, refit all clips/brackets, and keep clear of exhaust and moving parts. Heat sleeve is smart on V8s.
- After fitting, fill with Dexron III ATF.
- Raise the front wheels, start the engine, and turn lock‑to‑lock several times to bleed air.
- Top up to the “COLD/HOT” marks as appropriate.
- Recheck for leaks after a short drive.
Popular questions
What fluid does a 2000 Commodore power steering use?
Holden specifies Dexron III automatic transmission fluid for VT/VX power steering systems. It’s best not to mix types, if the history’s unknown, have the system flushed and refilled with fresh Dexron III for consistent feel and pump life.
How long do power‑steering hoses last on VT/VX?
Many last a decade or two, but heat, age, and fluid contamination shorten that. V8 cars can age hoses faster due to under‑bonnet temperatures. If in doubt, replace preventatively when signs of weeping or hardening appear.
Can a leaking hose damage the pump or rack?
Yes. Low fluid causes pump cavitation and noise, which can quickly score the internals. Ongoing leaks can also contaminate belts and mounts. Fix leaks promptly and keep the reservoir at the correct level to protect the whole system.
