DURITE DE DIRECTION ASSISTÉE

The Ford 1469170 is the Power Steering High-Pressure Hose Assembly (Feed Line) — Pump to Rack fitted to Ford Focus Mk2 (DA/HCP/DP) and Ford C-MAX Mk1 (DM2) built 2004-2012. The component is identified in Ford EU service documentation as "Hydraulic Hose, steering system from hydraulic pump to steering gear, without box nut." It is a high-pressure hydraulic hose assembly conveying pressurised power steering fluid between the engine-driven vane pump and the steering rack's rotary valve input port, operating at 80-160 bar continuous working pressure (200 bar peak transient at full-lock manoeuvres). The hose has pre-crimped steel end fittings for leak-free connection at both pump outlet and rack inlet positions.

The Focus Mk2 / C-MAX hydraulic power steering system has 4 components: (1) Engine-driven vane pump belt-driven, 80-160 bar working pressure; (2) High-pressure feed hose (1469170) routing pressurised fluid pump to rack; (3) Steering rack with integrated rotary valve directing fluid to hydraulic piston sides depending on steering input; (4) Low-pressure return hose returning spent fluid to reservoir.

3-layer construction: inner tube (synthetic rubber, ATF/PS-fluid compatible); reinforcement layer (steel wire braid, 200+ bar burst capability); outer jacket (synthetic rubber, heat/ozone/fluid resistant). End fittings are swaged steel assemblies providing leak-free unions. Routing has specific bend radii and clearances from exhaust and accessories.

Three failure mechanisms: (1) internal rubber tube delamination = flow restriction, heavy steering at sustained lock without leak; (2) external jacket cracking from heat / ozone exposes wire braid to corrosion; (3) fitting-to-hose joint weeping from pressure fatigue — oily residue progressing to active drip under full lock.

Tubes, pipes and hoses of vulcanised rubber other than hard rubber, reinforced or otherwise combined only with textile materials, with fittings, are classified under HS 4009.32. Confirm exact 10-digit subheading with your customs broker. Commercial invoice description: hydraulic high-pressure hose assembly (power steering system feed line, pump to steering rack), wire-braid reinforced synthetic rubber inner tube with pre-crimped steel end fittings, rated 80-160 bar continuous working pressure / 200 bar peak transient pressure, for passenger vehicle hydraulic power steering system.

Does NOT fit: Ford Focus Mk1 (1998-2004 previous generation) — different platform, different hose references; Ford Focus Mk3 (2010-2018) and Focus Mk4 (2018+) — predominantly equipped with Electric Power Assisted Steering (EPAS) eliminating the hydraulic hose entirely; Ford C-MAX Mk2 (2010-2019, post-DM2 generation) — uses EPAS, no hydraulic hose; Ford Fiesta (any generation) — different platform with different power steering hose references; Ford Mondeo / Galaxy / S-MAX (CD platform) — different chassis with different hose references; Ford Focus Mk2 with EPAS option (selected later 2009-2012 model years) — EPAS-equipped vehicles do NOT use this hydraulic hose; verify by inspecting under-bonnet for steering hydraulic system presence; Ford USA-market vehicles outside C1 platform applications — verify by Ford USA catalogue for your specific vehicle and trim. Always verify by reading the OEM number stamped on existing hose, or confirming with Ford parts catalogue by VIN, before ordering.

Difficulty: Moderate. Estimated time: 60–120 minutes. Access constraints — pump end fitting requires accessory belt removal on most Focus Mk2 / C-MAX applications; rack end fitting requires lower radiator air deflector removal.

1. 1
   Allow engine to cool fully before disconnecting any power steering hose fitting. Hydraulic fluid reaches 80-100°C at operating temperature and system retains residual pressure after shutdown. Disconnect reservoir cap to release system pressure before opening any fitting.
2. 2
   Position drain container below hose routing path — residual fluid in hose will drain when fittings loosened. Have absorbent cloths ready at both fitting positions.
3. 3
   Remove accessory belt (Focus Mk2 / C-MAX-specific procedure) for pump pulley clearance to pump fitting. Note belt routing for refitting.
4. 4
   Remove lower radiator air deflector for steering rack fitting access. Some applications require removing battery and battery tray for engine bay access.
5. 5
   Detach pressure line from line retainer clip and note routing through engine bay clip positions. On vehicles with automatic transmission, disconnect Turbine Shaft Speed (TSS) sensor connector at transmission and position away from pressure line.
6. 6
   Use correct open-ended spanners or flare nut crow-foot wrenches for both fittings. Power steering high-pressure fittings use flare connections with specific hex sizes. Using adjustable spanners rounds the fitting hex and makes future removal impossible. Apply second spanner to adapter / union at pump or rack to prevent adapter rotation with fitting.
7. 7
   Disconnect both end fittings and remove old hose from engine bay routing path. Photograph routing details before removal — new hose must follow exactly same path for clearance from hot exhaust components, rotating accessory pulleys, and steering column.
8. 8
   Compare new hose to old — verify length, curvature profile, end fitting threads / sealing geometry, and intermediate clip positions match exactly. Confirm OEM 1469170 or supersession 1704088 / 1743276 / 1477817 / 1488112.
9. 9
   Replace sealing O-rings at fittings — on Focus Mk2 applications, some fittings use O-ring seals (single-use components that must be replaced at each disturbance). Lubricate new O-rings with power steering fluid before installation.
10. 10
    Install new hose in engine bay routing path following photographed routing exactly. Reattach pressure line to retainer clips. Verify clearance from hot exhaust components and rotating pulleys.
11. 11
    Torque both end fittings to OEM specification using torque wrench. Focus Mk2 / C-MAX power steering high-pressure fittings typically torqued to 25-55 Nm depending on fitting size. Critical: undertightening at 160 bar produces immediate leak; overtightening strips rack or pump housing thread.
12. 12
    Refill reservoir with correct power steering fluid, bleed system by turning steering slowly lock-to-lock 5 times with front wheels off ground. Top up reservoir as level drops. Start engine and repeat lock-to-lock bleeding. Inspect all fittings under pressure for weeping; confirm steering assistance is light and consistent at all angles; verify no leaks after 10-minute test drive.
