1998 Nissan Navara Power-Steering-Fluid — What It Uses and How to Look After It

Technical sources including the Nissan D22 Navara Factory Service Manual (1997–2004), the 1998 Navara/Frontier Owner’s Manual, and well-known aftermarket workshop guides confirm the 1998 Nissan Navara (D22) uses a conventional hydraulic power steering system. These references specify automatic transmission fluid (ATF), typically Dexron II or Dexron III, as the correct power-steering fluid. So yes, power-steering fluid is absolutely relevant for this model.

On the 1998 Navara, power-steering fluid does the heavy lifting behind easy, predictable steering. The hydraulic pump pressurises the ATF and sends it to the steering gear, reducing the effort needed at the wheel and keeping feel consistent through city parks and country kays alike. Clean, correct fluid also lubricates the pump and rack components, cutting wear and keeping the system quiet.

For servicing, the go-to fluid is ATF meeting Dexron II or Dexron III specs, as noted in Nissan’s factory literature for the D22. Don’t mix fluid types, if you’re unsure what’s in there, it’s best to perform a complete change. Check the level on level ground with the engine off, using the reservoir markings (COLD/HOT as shown). The fluid should be a clear reddish colour, dark, burnt-smelling or foamy fluid is a prompt to replace and inspect for issues.

While some manuals don’t set a strict replacement interval, a practical workshop rule for an older hydraulic setup like the ’98 Navara is to refresh the fluid every 2–3 years or roughly 40,000–60,000 km—sooner if towing, off-roading, or in hot climates. Regular checks help spot weeps at hose crimps, the pump, or the rack boots before they become big leaks.

Two common ways to change it:

1. Drain-and-fill via the reservoir: extract old fluid, refill with fresh ATF, drive a few days, and repeat until the return fluid looks clean.
2. Return-line flush: disconnect the return hose at the reservoir, cap the spigot, and feed the hose into a catch bottle. With the front wheels off the ground, have a helper briefly start the engine while you add fresh ATF, stop immediately if flow stumbles—never run the pump dry.

After any fluid work, bleed air by turning the wheels lock-to-lock slowly with the engine off, then repeat briefly with the engine running. Recheck the level and inspect for leaks. Use fresh, sealed ATF and dispose of old fluid responsibly.

• Common signs it’s due: groaning/whining when turning, heavy steering, shudder, or fluid that’s dark or smells burnt.
• Handy tip: keep the belt tension and hose clamps in good nick—small tweaks here prevent big headaches later.

Popular questions about 1998 Nissan Navara power-steering-fluid

What power-steering fluid does a 1998 Nissan Navara take?
The D22 uses a hydraulic system that specifies ATF meeting Dexron II or Dexron III. Many owners and workshops stick with Dexron III. Avoid mixing different fluid types, if you’re changing brands or unsure what’s in there, do a full fluid refresh rather than a top-up.

How often should the power-steering fluid be changed?
For an older hydraulic setup, a 2–3 year or 40,000–60,000 km interval is a solid maintenance target. If the Navara tows regularly, sees dusty tracks, or operates in hotter regions, shorten the interval. Replace sooner if the fluid looks dark, smells burnt, or the steering gets noisy.

How do you bleed the system after a fluid change?
With the front wheels off the ground, top the reservoir and slowly turn the steering from lock to lock about 10 times with the engine off. Top up as needed. Then start the engine briefly, turn lock to lock a few more times, and recheck the level. If there’s foaming or chatter, let it sit, then repeat until the fluid is clear and quiet.
