1998 Mitsubishi Pajero Power-Steering Hose — What It Does and How to Look After It

Based on the Mitsubishi Pajero Workshop Manual (1997–1999, Group 37: Power Steering) and the Mitsubishi ASA parts catalogue for NL-series vehicles, the 1998 Pajero runs a conventional hydraulic power-steering system. That setup uses a belt-driven pump, a high‑pressure hose from the pump to the steering gear, and a low‑pressure return hose (often with a cooler loop). So yes, a power-steering hose is absolutely relevant and fitted to a 1998 Mitsubishi Pajero. These details are also consistent with common service data in Haynes and similar technical references for late‑90s Pajero/Montero models.

The hose’s job is straightforward but critical: the high‑pressure line carries ATF (automatic transmission fluid) from the pump to the steering box at serious pressure, while the return hose routes fluid back to the reservoir. Together they keep steering light and predictable at parking speeds and steady on the open road. Mitsubishi specifies ATF meeting Dexron II or III standards—don’t mix generic “power-steering fluid” unless it explicitly meets that spec.

As part of regular servicing, it’s smart to inspect the hoses every 10,000–15,000 kilometres. Under the bonnet, look for damp fittings, sweating rubber, chafing on brackets, or cracks and bulges. Check the reservoir level and fluid condition—ATF should be clean red, not black, gritty, or burnt-smelling. Make sure hose clips and brackets are snug and the lines aren’t rubbing on the body, crossmember, or exhaust.

• Heavier steering or intermittent assist at idle
• Whining or groaning from the pump
• Red ATF spots under the front end
• Foamy fluid in the reservoir
• Burnt ATF smell after a long drive

When replacement’s due, use quality hose assemblies that match your engine and VIN—diesel and petrol variants route differently and some have a factory cooler loop. Fit new sealing washers/O‑rings, follow the original routing and clip positions, and keep the line clear of heat sources. After installation, bleed the system: front wheels off the ground, turn lock‑to‑lock with the engine off, top up, then repeat with the engine running until bubbles disappear. Recheck for leaks after a day. Dispose of old ATF responsibly.

FAQs

What fluid should go in a 1998 Pajero’s power steering?
Mitsubishi specifies ATF meeting Dexron II or Dexron III. Many owners use a quality Dexron III. Avoid mixing in universal fluids that don’t state Dexron compatibility, and don’t top up with brake fluid (it’ll destroy seals). Check the cap or handbook to confirm.

How often should the power-steering hose be replaced?
There’s no fixed interval, replace on condition. On vehicles this age, any sweating, cracking, stiffness, or damp fittings are a cue to renew. It’s common to replace hoses when fitting a new pump or if the system shows recurring leaks or aeration.

Is it safe to drive with a leaking power-steering hose?
Not really. A small seep can quickly become a major leak, leading to sudden loss of assist and pump damage from running dry. If the hose is actively leaking, park it, top up only to move safely, and organise repair or a tow.
