Parts for your 1986 Mitsubishi Pajero-Power steering hose

1986 Mitsubishi Pajero Power Steering Hose

Technical sources confirm the 1986 Mitsubishi Pajero uses hydraulic power steering with dedicated hoses. The Mitsubishi factory service manual (Group 37 – Power Steering) for first‑gen Pajero/Montero details a pump, a high‑pressure hose, and a return hose. Mitsubishi ASA/CAPS parts catalogues list model‑specific high‑pressure hose assemblies for 1986 variants (e.g., MB241504/MB241505 and related supersessions) along with return hoses across 4G54 petrol and 4D56 diesel models. Mainstream aftermarket catalogues from brands like Gates and Edelmann also supply pressure hoses for 1986 Pajero/Montero applications. That makes a power‑steering hose relevant and expected on power‑assisted 1986 Pajero models.

On a 1986 Mitsubishi Pajero, the power steering hose does the heavy lifting behind the scenes. The high‑pressure line carries fluid from the pump to the steering gear under serious pressure, while the return hose sends it back to the reservoir to cool off and go again. Together they let the hydraulic assist do its thing so the wheel turns smoothly at parking speeds without a wrestle, even with chunky tyres and a bull bar fitted.

Because these hoses live near heat, vibration and road grime, they age. Rubber can harden and crack, crimps can seep, and the internal lining can shed, sending debris through the system. As part of routine servicing, it’s smart to give both lines a close look every 10,000–15,000 km: check for dampness at fittings, swelling, chafe marks, and any aerated or dark fluid in the reservoir. Keep an ear out for pump groan on lock and a nose out for that sweet, oily smell after a drive — both are classic clues.

If replacement’s on the cards, go for quality hose assemblies with the correct banjo fittings and length for the engine/steering combo. Always fit new sealing washers or O‑rings, route the lines exactly like the originals, and keep them well clear of exhaust and moving bits. After refitting, top up with the specified fluid (Dexron‑type ATF was originally called for on these), then bleed the system with the front wheels off the ground: engine idling, turn lock‑to‑lock slowly a few times, pause, recheck level, and repeat until the fluid runs clear and foam‑free.

Two bonus tips for old Pajeros: don’t over‑tighten the banjo bolts — follow workshop spec — and consider a full fluid flush if the old hose failed internally. Fresh fluid is cheap insurance for the pump and steering box. With decent hoses, correct fluid and a quick check each service, the Pajero’s steering stays light, tidy and reliable from the beach to the back blocks. If the steering still feels heavy or noisy after bleeding, revisit the hose routing and clamp positions, and inspect the pump belt tension and pulley alignment.

Popular questions about 1986 Mitsubishi Pajero power steering hose

What fluid should a 1986 Pajero use in the power steering system?
Period workshop literature specifies a Dexron‑type ATF for the first‑gen Pajero’s hydraulic power steering. Many owners use a modern Dexron III‑compatible ATF. Avoid universal “stop‑leak” additives on older hoses, they can swell rubber and mask problems rather than fix them. Always check your handbook or factory manual for final confirmation.

How can someone tell if the power steering hose is failing?
Look for wetness around hose crimps and banjo fittings, red or amber fluid on the chassis or driveway, foamy or discoloured fluid in the reservoir, pump groan at low speeds, or a steering feel that’s heavy and shuddery at full lock. Any of these signs suggests it’s time to inspect, tighten to spec, or replace the hose and refresh the fluid.

Are petrol and diesel Pajero hose assemblies interchangeable?
Not reliably. Hose length, bends and fittings can differ between 4G54 petrol and 4D56 diesel models, and by steering box and RHD/LHD layout. Match by VIN and production date using a parts catalogue, and double‑check routing against the old hose before fitting to avoid chafe or heat issues.
