Parts for your 2000 Mitsubishi Pajero-Power steering pump

2000 Mitsubishi Pajero Power Steering Pump — Purpose, Service and Replacement Advice

Based on technical references including the Mitsubishi Pajero/Montero NM-series (MY2000) factory service manual (Group 37 – Steering) and the Mitsubishi ASA electronic parts catalogue for the 3.2 Di‑D and 3.5 V6 variants, the 2000 Mitsubishi Pajero is fitted with a belt‑driven hydraulic power steering pump. So yes, a power steering pump is relevant to this model and is part of the standard steering system.

The power steering pump on a 2000 Pajero provides hydraulic pressure that makes turning the wheel light and predictable, on-road and off. Driven by the accessory belt, it draws fluid from the reservoir, pressurises it, and feeds the steering gear so the driver isn’t wrestling the wheel at low speeds or on corrugations. Kept in good nick, it reduces steering effort, noise, and wear on the rack and hoses.

As part of regular servicing, it pays to keep an eye on a few simple items:

• Fluid: Use Mitsubishi PSF or Dexron III ATF as specified in the factory manual. Refresh the fluid every 60,000 km or 2–3 years, especially if it’s dark, smells burnt, or looks aerated.
• Leaks: Check the pump shaft seal, high‑pressure hose fittings, and banjo washers for weeping. Fluid on the underside of the pump or frame rails is a giveaway.
• Belt: Inspect for cracks or glazing and set tension to spec after any adjustment or replacement.
• Noises: Whine on cold starts, groaning at full lock, or a chirp from the belt are early warning signs.

Replacing the pump is a straightforward job for a competent home mechanic with basic tools, but many owners prefer a workshop handle it. Typical steps include disconnecting the battery, draining or extracting fluid from the reservoir, removing the belt, undoing the pressure and return lines, swapping the pump, renewing O‑rings/crush washers, and bleeding the system. Bleeding is simple: with the front wheels off the ground, slowly turn lock‑to‑lock several times with the engine running, avoiding holding it hard against the stops. Top up until the fluid stays clear and bubble‑free.

For high‑km Pajeros, a quality remanufactured or new OEM‑equivalent pump is a solid choice. If steering effort increases, the wheel judders, or the pump whines even with fresh fluid and correct belt tension, plan a pump replacement to protect the steering rack and keep the big wagon easy to handle around town and on the tracks.

Popular questions about 2000 Mitsubishi Pajero power steering pumps

What fluid does the 2000 Pajero power steering pump use?
The 2000 Pajero typically specifies Mitsubishi Power Steering Fluid or Dexron III ATF (as per the factory manual). Mixing fluid types isn’t recommended, if unsure what’s in there, do a full flush so it’s consistent and clean.

Always check the cap or service data for the exact spec for the engine variant. Using the right fluid reduces noise, improves assist, and extends pump and rack life.

What are common signs the pump is failing?
Tell-tales include a whining or groaning noise that follows engine speed, heavy steering at low rpm, foamy or dark fluid, and leaks around the pump nose seal or high‑pressure hose. A slipping or glazed belt can mimic pump noise, so rule that out first.

If noises persist after a fluid refresh and belt check, the pump’s internal vanes or bearings may be worn.

Can the 2000 Pajero’s pump be rebuilt, or should it be replaced?
Many pumps can be rebuilt with a seal/bearing kit if the housing and shaft are in good condition. It’s cost‑effective for handy owners or specialist shops. If the shaft is scored, the body is pitted, or vane wear is severe, a quality reman or new unit is the safer bet.

Either way, fit new O‑rings/crush washers, flush the system, and bleed it properly to protect the replacement.
