Parts for your 2006 Mitsubishi Pajero-Power steering pump

2006 Mitsubishi Pajero Power Steering Pump

According to the Mitsubishi Pajero NM–NS Workshop Manual (Group 37: Power Steering) and the Mitsubishi ASA parts catalogue for 2006 build vehicles, the 2006 Mitsubishi Pajero (including late-2006 NS) uses a belt-driven hydraulic power-steering pump on both the 3.2 Di‑D 4M41 diesel and 3.8 V6 6G75 petrol engines. Mainstream aftermarket catalogues and workshop guides for 2000–2006 Pajero models also list a vane-type hydraulic pump with reservoir and high-pressure hose, confirming this vehicle is not fitted with an electric power steering system.

The power-steering pump’s job is to supply hydraulic pressure so the steering stays light and predictable at parking speeds yet stable on the open road. In a Pajero that tows, carries gear and sees corrugations or beach work, the pump keeps assist consistent even when wheel loads climb. It’s driven by the accessory belt, pulling fluid from the reservoir, pressurising it, and feeding the steering gear through the control valve to help turn the front wheels smoothly.

As part of routine servicing, a Pajero of this vintage benefits from regular checks of the pump, belt and hoses. Fluid condition should be inspected at each service, manufacturers often don’t specify a strict change interval, but many technicians refresh the fluid around 80,000–100,000 km, or sooner if it’s dark, smells burnt or is contaminated. Use the fluid specified in the owner’s manual (commonly ATF Dexron III or Mitsubishi PSF/SP‑III, depending on build). A fresh drive belt with correct tension and clean, dry connections go a long way to keeping the steering quiet and reliable.

• Signs it’s time for attention: whining or groaning on turns, a heavy or notchy steering feel, aerated fluid in the reservoir, leaks around the pump shaft or fittings, and blackened fluid.
• Replacement pointers: choose a quality new or reman pump, replace O‑rings/seals and any tired hoses, fit a new belt, and flush the system to remove debris that can shred a new unit.

Bleeding after service is straightforward: with the front wheels off the ground and engine off, turn lock-to-lock slowly to purge air, topping the reservoir as needed. Then start the engine and repeat, holding briefly near each lock without forcing it. Finalise at the MAX mark hot, check for seepage, and recheck belt tension after a short drive. Done right, the Pajero’s steering stays light, quiet and ready for the next trip.

Popular questions about 2006 Mitsubishi Pajero power-steering pumps

What fluid should go in the 2006 Pajero’s power steering?
The correct fluid is what Mitsubishi specifies for the exact build and market. Many 2006 Pajeros accept an ATF meeting Dexron III, while some listings call for Mitsubishi PSF or SP‑III. If the cap or service manual label differs, follow that. Mixing types isn’t recommended, if changing type, fully flush the system first.

How long does a Pajero power-steering pump typically last?
With clean fluid and a healthy belt, many pumps run well past 200,000 km. Heat, dirty fluid, oversized tyres and constant low-speed work can shorten lifespan. Early noise, weeping seals or metal in the fluid warrant prompt attention to protect the steering gear.

How is the system bled after replacing the pump?
Raise the front wheels, fill to the MAX mark, and with the engine off turn the wheel slowly lock-to-lock 10–15 times. Top up, start the engine and repeat gently, avoiding hard holds at full lock. When bubbles stop and assist is smooth, set the level hot at MAX and inspect for leaks.
