Parts for your 2000 Nissan Serena-Power steering pump

2000 Nissan Serena Power-Steering Pump — Purpose, Service and Replacement

Based on the Nissan Serena C23/C24 Factory Service Manual (Steering: ST section, circa 1999–2001) and the Nissan FAST electronic parts catalogue for the 2000 model year, the 2000 Nissan Serena is fitted with a hydraulic power-steering system using a belt-driven vane-type pump. Technical data for petrol (e.g., SR20DE/QR20DE) and diesel variants in these references show a conventional pump, reservoir, hoses and steering gear layout, not electric power steering. Industry guides such as Autodata’s service schedules for the era back this up with fluid, belt and leak checks specified at routine intervals.

On the Serena, the power-steering pump’s job is to supply pressurised fluid so the steering stays light at parking speeds and steady at highway pace. It’s driven by the accessory belt, drawing fluid from the reservoir and feeding the steering gear via high-pressure lines. If the pump’s weak, noisy, or leaking, steering effort rises and the wheel can feel notchy or groan on lock. Left unchecked, aerated fluid can damage the pump and seals.

For servicing, it’s sensible to treat the pump and fluid like any other wear-and-tear items. Use the fluid grade specified in the service manual for the exact engine/market—typically Nissan Power Steering Fluid or Dexron III ATF. Many workshops in Australia and New Zealand refresh the fluid around 60,000–80,000 km or when it’s dark, smells burnt, or shows metal fines. Expect roughly a litre for a drain-and-fill, a full exchange takes more.

• Inspect: Check the drive belt for glazing, cracks and correct tension, look for dampness around the pump body, hose crimps and rack boots.
• Flush: Turkey-baster the reservoir, refill with the correct fluid, and repeat over a few heat cycles—or use a proper exchange machine.
• Bleed: With front wheels off the ground, engine idling, turn lock-to-lock slowly, topping up to avoid aeration. Watch for foaming.
• Replace: If there’s persistent whining, metal sparkle in fluid, heavy steering at idle, or shaft play, it’s time for a pump. Always replace crush washers/O-rings, clean the reservoir screen, and set belt tension to spec.

A tidy system runs quiet, steers consistently, and doesn’t sip fluid. If there’s any doubt, a quick pressure and flow test as outlined in the FSM’s ST section will confirm pump health before committing to replacement.

Popular questions about 2000 Nissan Serena power-steering pumps

What power-steering fluid does a 2000 Nissan Serena use?
For most 2000 Serena variants the manuals specify Nissan Power Steering Fluid or Dexron III ATF. Don’t mix brands or types, if changing over, do a full exchange. Aim for a clean, cherry-red fluid with no burnt smell.

How can they tell the pump needs replacing?
Common signs include a loud whine that follows engine speed, heavy or jerky steering at idle, obvious leaks at the pump shaft or hose fittings, and glitter in the fluid. A pressure/flow test per the service manual will confirm a weak pump.

Is the 2000 Serena’s power steering electric or hydraulic?
It’s hydraulic. Technical references for C23/C24 Serena list a belt-driven vane pump and hydraulic rack—no electric assist on 2000 models.
