1997 Mitsubishi Lancer Power-Steering Pump: Purpose, Service and Replacement

Based on factory and aftermarket technical references, the 1997 Mitsubishi Lancer models equipped with power-assisted steering use a belt-driven, hydraulic power-steering pump. The Mitsubishi Lancer CK/CJ/CE factory service manual (Steering section) specifies a vane-type hydraulic pump and reservoir feeding a power rack. Mitsubishi ASA parts catalogues list complete pump assemblies and seals for 1997 Lancer variants, and common workshop manuals (e.g., Gregory’s/Haynes for 1996–2003 Lancer) outline pump service procedures. Some entry-level trims in certain markets could be manual-steer, but Australian and New Zealand-delivered 1997 Lancers with power steering rely on this hydraulic pump.

The pump’s job is simple but crucial: it pressurises fluid so the steering rack gets a helping hand, keeping the wheel light at low speeds and steady on the open road. It’s driven by the accessory belt, pulling fluid from the reservoir, through the pump, and on to the steering gear before returning to the tank.

For servicing, regular fluid checks matter. The system typically uses Mitsubishi PSF or ATF meeting Dexron II/III, owners should confirm the cap or handbook for the exact spec. Fresh, clean fluid (cherry red, no burnt smell) keeps the pump happy. A periodic drain-and-fill or professional flush can be considered every 60,000–100,000 km, especially if the steering feels heavy or the fluid is dark.

It also pays to keep an eye on the drive belt and hose condition. A slipping or glazed belt, cracked return hose, or weeping pressure hose can invite pump noise and aeration. If replacement is needed, a quality remanufactured or new unit, fresh O-rings, and new copper washers for any banjo fittings are the go. Priming the pump with fluid and bleeding the system properly helps avoid cavitation.

• Common pump symptoms: whining on turns, heavy feel at parking speeds, aerated or discoloured fluid, leaks at the pump shaft or fittings, and a belt squeal on start-up.
• Basic bleed tip: front wheels off the ground, slowly turn lock-to-lock with engine off to purge air, top up, then idle and repeat—without holding hard against the stops.

When done correctly—correct fluid, sound belt tension, and tight, leak-free lines—the 1997 Lancer’s hydraulic pump delivers years of quiet, predictable steering that suits Aussie and Kiwi city commutes and long highway runs alike.

Popular questions

What fluid does a 1997 Mitsubishi Lancer power-steering system use?
Most 1997 Lancers call for Mitsubishi PSF or ATF to Dexron II/III. The reservoir cap or owner’s handbook is the final word. In Australia and New Zealand, Dexron III ATF is commonly used. Avoid mixing fluid types and skip “stop-leak” unless diagnosing a specific issue.

How is the power-steering system bled after pump replacement?
With the front wheels off the ground, fill the reservoir, then slowly turn the wheel lock-to-lock with the engine off several times. Top up as bubbles clear. Start the engine, idle, and cycle the steering again without holding full lock. Recheck fluid level and inspect for leaks.

Why does the pump whine when turning, especially when cold?
Likely causes are low fluid, air in the system, a slipping belt, or a partially blocked reservoir screen/return hose. Topping up with the correct fluid, bleeding properly, and checking belt condition usually restores quiet operation.
