Parts for your 2017 Mitsubishi Lancer-Power steering pump

2017 Mitsubishi Lancer Power-Steering Pump

Based on the Mitsubishi Lancer CF (2016–2017) Service Manual – Group 37: Steering, and OEM parts catalogues (Mitsubishi ASA/Global EPC), the 2017 Mitsubishi Lancer with 2.0L (4B11) and 2.4L (4B12) petrol engines uses a belt-driven hydraulic power-steering pump. It is not an electric power steering (EPS) system, so a conventional pump and fluid are absolutely relevant on this model.

On a 2017 Lancer, the power-steering pump’s job is to supply hydraulic pressure to the steering rack, making the wheel feel light at parking speeds and stable at highway pace. Driven by the engine via the accessory belt, the vane-type pump moves fluid through the system, with a built-in flow/pressure control to balance assist. When it’s healthy, steering is smooth and predictable, when it’s on the way out, the driver may notice a whine that rises with revs, heavier steering, or fluid aeration in the reservoir.

For day-to-day care, it pays to keep an eye on the fluid and the drive belt. At regular services, check the fluid level and colour, and top up only with the fluid specified in the owner’s manual (genuine Mitsubishi PSF or an equivalent ATF to the correct spec, as listed by Mitsubishi). If it’s dark, burnt-smelling, or glittery, organise a flush and chase any leaks at the pump, pressure hose, return hose, and rack. Don’t forget the belt—cracks, glazing, or slack tension can cause noise and poor pump output.

When replacement is on the cards, doing the job properly avoids headaches later. A smart approach is:

• Fit a quality pump and new O-rings/seals on the pressure and return fittings.
• Flush the system to clear out debris so the new pump isn’t chewed up by old contaminants.
• Bleed the hydraulics: with the front wheels off the ground, turn lock-to-lock (engine off) several times, then start the engine and repeat until there are no bubbles and no foaming in the reservoir.
• Set belt tension to spec and recheck after a short drive.

Common red flags include a groan or whine that tracks engine speed, intermittent assist when cold, and visible leaks around the pump snout or hose crimps. Driving with low fluid can cook the pump quickly, so if the wheel suddenly gets heavy, it’s best to park it, fix the leak, and refill with the correct fluid. A quick road test and a recheck for seepage under the bonnet round out a tidy repair.

• Does the 2017 Mitsubishi Lancer have a power-steering pump?
  Yes. Technical documentation for the CF-series Lancer (2016–2017) and OEM parts catalogues confirm a belt-driven hydraulic power-steering pump on the 2.0L and 2.4L petrol models. It’s not an EPS setup.
• What fluid should be used in a 2017 Lancer power steering system?
  Use the fluid specified by Mitsubishi for this model—genuine Mitsubishi PSF or an equivalent ATF meeting the stated Mitsubishi/DEXRON-type specification. Check the owner’s manual or a dealer parts counter and avoid mixing different fluid types.
• How often should the power-steering fluid be changed?
  There’s typically no strict factory interval, but many workshops in Australia and New Zealand recommend a preventative fluid exchange around 60,000–100,000 km, or sooner if the fluid is discoloured, contaminated, or there’s steering noise.
