Parts for your 1999 Mitsubishi Pajero-Power steering hose

1999 Mitsubishi Pajero power-steering hose — what it does and how to look after it

Yes, a power-steering hose is absolutely relevant to a 1999 Mitsubishi Pajero. Mitsubishi’s factory Workshop Manual for the Pajero/Montero (Steering, Group 37) and the Mitsubishi ASA electronic parts catalogue for 1997–2000 models both show a hydraulic power-steering system with a pump, steering gear and dedicated high-pressure and return hoses. Late ‘99 NM models with rack-and-pinion and earlier ‘99 NL models with a steering box alike use hydraulic hoses to move ATF under pressure for steering assist.

On this Pajero, the power-steering hose set does two main jobs: the high‑pressure hose carries fluid from the pump to the steering gear so you get light, confident steering, while the low‑pressure return hose takes fluid back to the reservoir. Many have a small cooler loop in front of the radiator to keep fluid temps in check when towing or tackling corrugations.

Keeping these hoses in good nick matters. A tired hose can leak, aerate the fluid or collapse internally, which leads to heavy steering, pump whine and a messy driveway. Typical signs it’s time for attention include:

• Red/brown ATF weeping around crimped fittings or banjo bolts
• Steering effort rising at idle or when parking
• Chirps or whine from the pump, foamy fluid in the reservoir
• ATF smell on the exhaust or greasy buildup on the crossmember

As part of regular servicing, give the hoses and clamps a close look every 10,000–15,000 km. Wipe them clean, then check again after a drive. Make sure the hose routing is clear of the exhaust and not rubbing on the chassis or sway bar. Top up only with Mitsubishi‑approved ATF meeting Dexron III spec, not generic “power steering fluid”, and replace the reservoir screen if it’s clogged.

When replacing a hose, use quality parts with the correct crimped ends. Fit new sealing washers or O‑rings at banjo/flare connections, and snug everything to the workshop manual torque. A flare‑nut spanner helps avoid rounding fittings. After installation, bleed the system: front wheels off the ground, engine running, turn lock‑to‑lock slowly 10–15 times, pausing to top up until bubbles clear. If the old hose shed debris, consider a fluid flush and check the cooler for kinks. Done right, the Pajero’s steering stays light, quiet and leak‑free for years of touring.

Popular questions about 1999 Mitsubishi Pajero power-steering hoses

What fluid should be used in the 1999 Pajero’s power steering?
Mitsubishi specifies automatic transmission fluid that meets Dexron III for the power-steering system. Using the correct ATF keeps seals happy, protects the pump and maintains consistent steering feel in hot Aussie and Kiwi conditions.

How can someone tell if the power-steering hose is failing?
Look for wetness around hose crimps or fittings, low fluid level, a whining pump, or heavier-than-normal steering at parking speeds. Any ATF smell or drips on the front crossmember are a giveaway. If leaks are found, address them promptly to avoid pump damage.

How often should the hoses be replaced?
There’s no fixed interval, as life depends on heat, age and off-road use. Inspect at each service and replace at the first sign of cracking, swelling, chafing or leaks. Many original hoses last well over 10 years, but high-heat or towing duties can shorten that.
