Detailed Description

Rein PSH0456 is a power steering reservoir hose engineered as an OE-style replacement for the suction side of the steering system. It is formed to follow the original hose shape and uses a braided rubber compound selected for durability in the engine bay, where outside heat and underhood exposure can accelerate hose wear. This part cross-references Toyota 4434808030 for the same application.

Compatible With 2007-2010 Toyota Sienna, reservoir to pump. The Rein PSH0456 is a practical replacement when the original hose shows cracking, seepage, soft spots, or heat-related deterioration. It is also a strong match when the steering system has been serviced and the suction hose needs to be renewed to maintain proper fluid flow.

Common Repair Reasons

• Power steering fluid seepage at the reservoir hose
• Cracked or hardened hose material from heat exposure
• Loss of steering assist caused by suction-side air intrusion
• Noise or cavitation from a restricted or aging hose
• Preventive replacement during steering system service

Installation Notes

Verify routing against the original hose before installation and confirm the reservoir-to-pump position on the vehicle. Inspect mating fittings, clamps, and nearby heat sources for wear or damage before final assembly. After installation, check fluid level, bleed the steering system as required, and inspect for leaks with the engine running and the wheels turned lock-to-lock.

Quality Assurance

Rein OE Quality hoses are built to OE-comparable standards and include protective features specified for the application. PSH0456 is backed by a 24-month/24,000-mile warranty.
