2002 Daihatsu Gran Move Power-Steering Hose

Yes, the 2002 Daihatsu Gran Move uses a power-steering hose. Technical sources including the Daihatsu Gran Move/Pyzar Workshop Manual (Steering section) and the Daihatsu Electronic Parts Catalogue for chassis codes such as G301/G303 list a hydraulic power-steering system with a belt-driven pump, a high-pressure hose and a low-pressure return hose. Aftermarket fitment catalogues also supply dedicated pressure and return hoses for the 2002 Gran Move, confirming the hose is a relevant, fitted component.

On the Gran Move, the power-steering hose carries automatic transmission fluid (ATF) between the pump and steering rack, letting the pump deliver high pressure so the wheel feels light around town and steady on the motorway. The high-pressure line is reinforced to handle serious pressure, while the return line directs fluid back to the reservoir. After two decades of heat, vibration and the odd splash of road grime, these hoses can harden, sweat, or crack—so they deserve a spot on any service checklist.

What owners should watch for:

• Heavier steering at low speeds, shuddering, or a whining pump
• Reddish/brown fluid spots under the front of the car or damp hose crimps
• Low fluid level in the reservoir or aerated/foamy fluid

Service tips for a Gran Move power-steering hose:

• Inspect hoses every service (or at least annually). Look for wetness at fittings, cracks, swelling, or chafe marks.
• Use the correct fluid: Daihatsu specifies ATF Dexron II or Dexron III for the power steering. Don’t mix fluid types.
• If replacing the pressure hose, fit new sealing washers/O-rings, keep everything spotless, and avoid twisting the rack fittings.
• Flush contaminated fluid and bleed the system by turning lock-to-lock with the front wheels off the ground. Don’t hold the wheel hard against the stops.
• Be safety-smart: the system runs high pressure—let it cool, wear eye protection, and cap open lines to keep dirt out.

A fresh hose protects the pump, keeps steering effort light, and stops leaks that can damage belts and bushings. Genuine or quality aftermarket hoses both work—just match by VIN/chassis code, as Gran Move variants (engine and rack differences) can change hose shape and fittings. If the hose shows its age or the fluid’s dropping, sorting it now is cheaper than a new pump later.

Popular questions about the 2002 Daihatsu Gran Move power-steering hose

Which fluid should go in the Gran Move’s power steering?
For this model, Daihatsu specifies ATF Dexron II or Dexron III in the power-steering system. Keep it clean, don’t mix brands or types, and top up only after checking for leaks. If the fluid is dark, burnt, or gritty, plan a flush when replacing hoses.

How do you bleed the Gran Move’s power steering after a hose change?
Raise the front wheels, fill the reservoir to the MAX line, then turn the steering slowly lock-to-lock about 10–15 times with the engine off. Top up, start the engine, and repeat a few slow lock-to-lock turns without holding it at the stops. Recheck for bubbles and leaks, then set the level once the fluid is clear and quiet.

Are all Gran Move power-steering hoses interchangeable?
Not always. Hose routing and fittings can vary by chassis code (e.g., G301 vs G303), steering rack type and market spec. Match the hose using the VIN or exact model details to avoid fitment hassles.
