1998 Mitsubishi Lancer Power Steering Pump — What It Does and How to Look After It

Technical references including the Mitsubishi Lancer CE (1996–2003) factory service manual, the Mitsubishi ASA electronic parts catalogue, and major aftermarket catalogues (Gates/Dayco belt and hose guides) confirm that 1998 Lancer models equipped with power steering use a belt-driven hydraulic power steering pump. In Australia and New Zealand, power steering was common across CE Lancer trims, making the pump a relevant service item under the bonnet.

The power steering pump on a 1998 Mitsubishi Lancer is a belt-driven vane-type unit that pressurises fluid and feeds the steering rack, so the wheel feels light and predictable at parking speeds while staying stable on the open road. When it’s healthy, steering effort is consistent, quiet and drama-free. When it’s tired, it’ll let everyone know with groans, whines, leaks and a steering feel that swings from heavy to vague.

For routine servicing, checking the fluid and drive belt is the best start. Use the correct fluid: Mitsubishi commonly specifies ATF meeting Dexron II/III for the CE Lancer’s hydraulic steering, and many shops in AU/NZ service these cars with Dexron III ATF or Mitsubishi PSF. Keep the level between the marks when hot, and watch the fluid colour—dark, burnt or glittery fluid means it’s time for a flush and a closer look at pump wear.

• Inspect the pump, hoses and rack for wet spots around hose crimps, banjo fittings and the front pump seal.
• Listen for whine that rises with revs—often low fluid, aeration or a failing pump.
• Check belt condition and tension, cracks, glazing or chirps under load mean it’s due.

Planned maintenance helps: a fluid exchange every 40,000–60,000 km (or 2–3 years) keeps varnish at bay and the vanes happy. If the pump is noisy after a fluid refresh and the belt is right, the internal clearances may be gone—replacement is the cure.

When replacing the pump on a 1998 Lancer, it’s smart to fit new sealing washers/O-rings on the pressure line, inspect the return hose, and flush the system so the new pump isn’t fed old grit. After install, bleed by turning the steering from lock to lock with the front wheels off the ground, engine off first, topping as bubbles clear, then finish with the engine running. Don’t overfill, don’t hold hard against the stops, and recheck for leaks after a short drive. Do it right and the steering will feel light as a feather and behave impeccably in city traffic and out on the motorway.

• Common symptoms of trouble: heavy steering, groaning on turns, fluid loss, shimmering or jerky feel at low speed.
• Quick wins: correct fluid, clean reservoir screen, sound belt, tidy hoses and clamps.

FAQs

What power steering fluid should a 1998 Mitsubishi Lancer use?
The CE Lancer typically specifies ATF meeting Dexron II or Dexron III for the hydraulic power steering system. Many Australian and New Zealand workshops use Dexron III ATF or Mitsubishi-branded PSF that meets the same spec. Stick with one compatible type and avoid mixing different formulations.

How can someone tell if the pump on a 1998 Lancer is failing?
Classic signs include a rising-and-falling whine with engine speed, heavier steering at low speed, foamy or dark fluid in the reservoir, and fresh leaks at the pump or pressure hose. If a fluid flush and correct belt tension don’t quiet it down, the pump’s internal vanes and bearings are probably worn.

Is bleeding necessary after replacing the power steering pump?
Yes. Air in the system causes noise, cavitation and poor assist. Bleed with the front wheels off the ground: engine off, turn lock-to-lock several times, top up, then repeat with the engine running until bubbles stop and the fluid stays at the correct mark.
