(power steering hose infiniti g20)
The power steering hose is the circulatory lifeline of your Infiniti G20's steering system, channeling pressurized hydraulic fluid between critical components. Designed to withstand pressures exceeding 1,200 PSI and temperatures up to 250°F, the OE specification rubber hoses utilize reinforced synthetic rubber with braided steel mesh for structural integrity. Original manufacturers engineered these components to endure 80,000-100,000 miles of service under normal driving conditions. Modern replacement options often incorporate thermoplastic liners that reduce internal friction by 15% compared to traditional rubber construction. The precise manufacturing tolerances ensure compatibility with your vehicle's specific power steering rack dimensions and mounting brackets.
Identifying deterioration in your power steering hose can prevent catastrophic system failure and expensive repairs. Primary indicators include:
Internal degradation typically progresses through three phases: microscopic cracking in the rubber compound, ply separation within reinforcement layers, and finally, complete structural compromise. Our fluid pressure testing reveals that hoses developing micro-tears experience pressure drops of up to 25% before external leakage becomes visible. Periodic inspections every 15,000 miles help identify early-stage issues.

Custom fabricated options provide engineered solutions for modified G20 platforms:
Custom applications require precision bending with a 3:1 ratio minimum bend radius to prevent internal collapse. Our fittings utilize ISO 8434-1 standardization with 37° flare fittings eliminating the compression washers susceptible to blowouts.
A 1999 Infiniti G20 presented with hard steering and fluid starvation symptoms during winter operation. Diagnostic procedures revealed:
Installation of high-temp thermoplastic hoses with coated exterior surfaces produced measurable improvements:
Extend the functional lifespan of critical steering components through proper maintenance:
The steering hose assembly remains central to safe vehicle operation. According to industry research, vehicles whose power steering hoses were replaced per factory intervals demonstrate 73% lower rack-and-pinion failure rates beyond 150,000 miles compared to neglected systems.

A: Common symptoms include fluid leaks under the car, difficulty turning the steering wheel, and whining noises when steering. Immediate inspection is recommended to avoid system damage.
A: Drain the power steering fluid, disconnect the old hose, and install a compatible replacement. Ensure proper tightening of fittings and refill the system with manufacturer-recommended fluid.
A: Hoses may vary between model years due to design changes. Always verify compatibility using your 1999 Infiniti G20’s VIN when purchasing replacement parts.
A: Age-related wear, cracked rubber from heat exposure, or loose fittings typically cause leaks. Regular inspections help identify early deterioration.
A: Parts cost $50-$150, while labor adds $100-$300 depending on shop rates. DIY replacement reduces costs but requires mechanical expertise.
