1999 Mitsubishi Pajero Power Steering Fluid

For the 1999 Mitsubishi Pajero, power steering fluid is absolutely relevant and used. Mitsubishi’s own service literature for late-1990s Pajero models (V20/NL series) describes a hydraulic power-steering system that specifies ATF meeting Dexron II or Dexron III standards for the reservoir. This is echoed across workshop manuals for the period (Group 37A – Power Steering) and owner’s handbooks for closely related early-2000s Pajero models in Australia and New Zealand, which also nominate ATF Dexron III for the power steering system.

On this Pajero, the power steering fluid does the heavy lifting. It transmits hydraulic pressure from the pump to the steering gear, giving lighter wheel effort at parking speeds. Beyond that, it lubricates the pump and rack internals, carries away heat, and protects seals from drying out. When the fluid ages or gets contaminated, the driver might notice extra steering weight, a groaning or whining noise from the pump, shudder on full lock, or fluid that looks dark and smells burnt.

Mitsubishi commonly calls for inspection rather than a strict replacement interval, but in Aussie and Kiwi workshop practice it’s smart to refresh the fluid roughly every 60,000–100,000 km or about every 4 years, sooner if it’s discoloured. Use a quality ATF meeting Dexron II or Dexron III. Avoid mixing with generic “power steering fluid” unless it explicitly states Dexron compatibility.

• Checking level: Park level, warm the vehicle with a short drive, switch off, then use the reservoir dipstick. Keep fluid between the HOT or COLD marks as applicable.
• Top-up technique: Add small amounts only, don’t overfill. Wipe the cap and area clean first to keep grit out.
• Bleeding air: After a fluid change, raise the front wheels and slowly turn lock-to-lock several times with the engine idling, then recheck the level.

For a driveway service, a series of partial exchanges works well: suck old fluid from the reservoir, refill with fresh ATF, run the engine and turn the wheel, and repeat until the fluid stays cherry red. For a complete exchange, many workshops disconnect the low-pressure return and feed fresh ATF while the old fluid is directed into a container. Expect around 1–2 litres to do a thorough exchange.

Keep an eye on common leak points—hose crimps, pump shaft seal, and steering rack boots. If the fluid drops quickly after topping up, get it inspected before the pump runs dry.

Popular questions

What type of power steering fluid does a 1999 Mitsubishi Pajero use?
It uses automatic transmission fluid (ATF) meeting Dexron II or Dexron III specifications. Many owners in AU/NZ choose a reputable Dexron III ATF for consistent performance and seal compatibility.

How often should the power steering fluid be replaced?
Mitsubishi focuses on condition checks, but a practical approach is every 60,000–100,000 km or about every 4 years. Replace sooner if the fluid looks dark, smells burnt, or the steering gets noisy or heavy.

How do you check the power steering fluid level on a 1999 Pajero?
Warm the vehicle with a short drive, park level, switch the engine off, then use the dipstick on the reservoir. Read against the HOT or COLD marks as appropriate, and keep the level between the lines. Top up only with Dexron II/III ATF.
