Parts for your 2023 Mitsubishi Triton-Power steering pump

2023 Mitsubishi Triton power-steering-pump — what it does and how to look after it

Yes, the 2023 Mitsubishi Triton uses a power-steering pump. Technical references including the MR Triton Workshop Manual (2019–2023, Group 37 – Power Steering), Mitsubishi Motors Australia MY23 Triton specification sheets, and equivalent L200 service documentation all describe a hydraulic power-assisted rack-and-pinion system driven by a belt-mounted vane pump. That means a conventional hydraulic power-steering pump is fitted to 2023 Triton models rather than electric power steering.

On the 2023 Triton, the power-steering pump’s job is to supply pressurised fluid to the steering rack so turning the wheel feels light and predictable, even with a load in the tray or on rough tracks. It’s a tough bit of kit, built to handle towing and off-road work common across Australia and New Zealand. When everything’s healthy, assistance is smooth, quiet, and consistent at parking speeds and on the highway.

As part of regular servicing, it’s smart to give the pump and hydraulic circuit a once-over. Check the drive belt for cracks, glazing, or slack. Inspect hoses, clamps, and the pump body for weeps or leaks. Look at the fluid in the reservoir, it should be clean, the right colour, and free from foam or metallic sparkle. Use only a Mitsubishi-approved power-steering fluid/ATF per the owner’s or service manual (many Triton MR models specify an ATF such as SP-III or an equivalent Mitsubishi PSF). Keeping to the correct fluid is key for seal life and pump durability.

• Common warning signs: a whine or groan when turning, heavier steering at low speed, fluid loss under the front of the ute, or aerated/dirty fluid in the reservoir.
• Good practice: bleed the system after any hose or pump work by turning lock-to-lock with the front wheels raised, topping fluid as needed, and avoiding holding full lock for more than a couple of seconds.

Replacement is straightforward for a trained tech: isolate the battery where required, drain/contain fluid, swap the pump with new O-rings and seals, set correct belt tension, then refill and bleed. Many workshops recommend flushing old fluid, especially if there’s noise or contamination. While there’s no hard-and-fast replacement interval, fluid condition checks each service and a preventive fluid change around 60,000–100,000 kilometres can pay off, particularly for vehicles that tow, work hard, or see corrugations. Keeping the hydraulic system clean and leak-free helps the Triton steer sweetly and protects the rack and pump for the long haul.

Popular questions about the 2023 Mitsubishi Triton power-steering-pump

Does the 2023 Triton use electric power steering?
No. Technical documentation for the MR-series Triton (through MY23) specifies hydraulic power steering with a belt-driven pump. Some later, next-generation models moved to electric assist, but the 2023 Triton retains a hydraulic setup.

What fluid should go in the Triton’s power steering?
Use the fluid type specified in the owner’s or workshop manual for the MR Triton. Many listings call for a Mitsubishi-approved ATF (e.g., SP-III) or designated PSF. Sticking to the exact spec helps avoid noise, seal issues, and premature pump wear.

How long should a power-steering pump last on a Triton?
With clean, correct fluid and a healthy drive belt, pumps often last well past 150,000 km. Heavy towing, off-road work, heat, or running low on fluid can shorten life. Early attention to noises or leaks usually prevents bigger repairs down the track.
