Parts for your 1998 Nissan Primera-Power steering hose

1998 Nissan Primera power steering hose: what it does and how to look after it

On the 1998 Nissan Primera (P11), a power steering hose is absolutely relevant and fitted. Technical references including the Nissan Primera P11 Factory Service Manual (Steering/Power Steering “ST” section), the Nissan EPC/FAST parts catalogue, and mainstream repair guides like the Haynes manual confirm the car uses a belt-driven vane pump and hydraulic lines. Typical listings show a high-pressure hose (e.g., Nissan 49720-2J000, engine-dependent) and a low-pressure return hose (e.g., 49725-2J000), running between the pump, rack, and reservoir.

In plain terms, the power steering hose carries fluid under pressure from the pump to the steering rack, and returns it to the reservoir. That hydraulic assist is what keeps the Primera light and easy to steer around town and steady on the motorway. When the hose ages—think hardened rubber, cracked outer cover, or corrosion at crimped fittings—leaks can start, the pump can whine, and steering can get heavy. Left too long, low fluid can take out the pump and make a proper mess on the driveway.

As part of regular servicing, a quick look-over of the power steering hoses pays off:

• Check for dampness or red ATF staining around hose crimps, banjo fittings at the pump and rack, and along the rubber sections. Any weeping means it’s time to sort it.
• Use the correct fluid: Nissan specifies ATF meeting Dexron II/III. Keep it at the “COLD” mark when checked on a level surface.
• If replacing, choose OE or OE-quality hoses, renew sealing washers, and route/clamp the lines exactly as per the workshop manual so they don’t chafe or touch hot/exhaust areas.

Bleeding after hose replacement is straightforward:

1. Raise the front wheels. Fill the reservoir with the correct ATF.
2. With engine off, turn the wheel lock-to-lock 10–15 times, topping up as bubbles purge.
3. Start the engine and slowly go lock-to-lock a few more times. Don’t hold it on the stops for more than a couple of seconds.
4. Recheck level and inspect for leaks after a short drive.

Most P11s are now well into classic daily territory, so a preventative hose replacement—especially the high-pressure line—can save a pump and keep the steering feel spot-on. Dispose of old ATF responsibly, and if fittings look seized or corroded, let a pro handle the job to avoid damaging the rack or pump.

What fluid does a 1998 Nissan Primera use in the power steering system?

Nissan specifies automatic transmission fluid meeting Dexron II or Dexron III for the P11’s power steering. Using the correct ATF keeps the pump lubricated and the rack happy. Mixing fluid types isn’t recommended—if unsure what’s in there, do a full flush and refill with fresh Dexron III.

How can someone tell if the power steering hose on a Primera is failing?

Common signs include red or brown oily wetness at the hose crimps or fittings, a whining or groaning noise from the pump, heavier-than-normal steering, and low fluid in the reservoir. You might also spot drips under the front left of the engine bay after parking.

Is it safe to drive with a leaking power steering hose?

It’s not a great idea. Leaks can quickly drop fluid level, making the steering heavy and risking pump damage. Fluid can also reach hot components. If a leak is noticed, top up to get home or to a workshop, then repair promptly rather than putting it off.
