1987 Mitsubishi Pajero Power-Steering Hose — What It Does and How To Look After It
Referencing the Mitsubishi Pajero/Montero Factory Service Manual for 1983–1991 (Group 37: Power Steering) and the Mitsubishi ASA/CAPS parts catalogue for 1987 L040/L140 chassis, the 1987 Mitsubishi Pajero uses a hydraulic power steering system with both a high-pressure hose and a low-pressure return hose. Those documents list the pressure hose between the pump and steering gear and a return hose to the reservoir, confirming a power-steering hose is absolutely relevant and fitted on this model.
On a 1987 Pajero, the power-steering hose is the lifeline of the hydraulic assist. The high-pressure side takes fluid from the pump to the steering box, while the return hose feeds it back to the reservoir. That closed loop lets the big wagon steer smoothly at low speeds — no wrestling the wheel in a car park.
Because this Pajero’s now well into classic territory, hose condition matters. Rubber hardens, crimps age, and fittings can sweat. During regular servicing, it’s smart to inspect both hoses for dampness, cracks, chafe marks, and bulges — especially around bends, brackets, and near heat sources. Any sign of red or amber ATF on the chassis rail or crossmember, a whining pump, or heavier-than-normal steering is a cue to act.
Replacement is straightforward if tackled methodically. Go for a quality OEM-equivalent pressure hose with the correct length, banjo fittings, and heat shielding. Always fit new sealing washers or O-rings where specified. For the return line, fresh hose and proper clamps (not worm-drives if the spec calls for spring clamps) help prevent weeps.
- Degrease the area so leaks are easy to spot later.
- Drain/contain old fluid, cap open lines, and keep debris out.
- Route the new hose exactly like the original — away from exhaust and moving parts.
- Refill with ATF meeting Dexron II spec (or a suitable Mitsubishi-approved PSF for the era).
- Bleed by turning lock-to-lock with the front wheels off the ground, topping up as bubbles clear.
Check for leaks under load, then recheck fluid level after a short drive. As a rule of thumb, inspect the hoses at every service, and don’t be shy about pre-emptive replacement on 30-plus-year-old lines. Fresh hoses keep the steering light, the pump quiet, and the driveway free of stains — too easy.
FAQs
What fluid should go in a 1987 Pajero’s power steering?
For most first-gen Pajero systems, an ATF meeting Dexron II specification is appropriate, unless a previous steering box or pump swap specifies otherwise. Using the correct spec fluid keeps the pump happy and reduces seal wear. If in doubt, check the factory manual or the label on the reservoir cap.
How can someone tell if the high-pressure hose is failing?
Common signs include fresh ATF around the hose crimps or banjo fittings, a burnt-ATF smell near the exhaust, heavier steering, or pump whine that changes with steering input. Any visible cracking, swelling, or chafe marks is grounds for replacement before it lets go under pressure.
Can the hose be repaired, or should it be replaced?
Low-pressure return hoses can sometimes be replaced with quality oil-rated hose and proper clamps. High-pressure hoses should be replaced with an OEM or professionally fabricated assembly rated for steering pressures. Quick fixes are false economy — a proper hose saves the pump and avoids roadside dramas.
