Rein PSH0598 Power Steering Reservoir Hose - Reservoir To Pump

OE-Style Power Steering Suction Hose

Rein PSH0598 is a direct-fit power steering reservoir hose for reservoir-to-pump routing on select Nissan and INFINITI applications. It is built with an OE-quality braided rubber compound to handle engine bay heat and power steering fluid exposure while maintaining the correct formed shape.

For Nissan 370Z and INFINITI G37, Q60, Q40, EX35, EX37, G35, G25, and QX50 applications, this hose is made to match the original routing and connection points. Rein PSH0598 is a practical replacement when the original suction hose shows age-related wear, seepage, or heat damage.

Key Features

• Direct-fit replacement hose with clamps
• OE-quality braided rubber compound construction
• Formed to follow factory reservoir-to-pump routing
• Pre-attached protective jacket(s) and heat sleeve(s) where required
• Built for the engine bay environment and hot power steering fluid flow

Detailed Description

Rein PSH0598 is a power steering reservoir hose designed for reservoir-to-pump service on 2007-2020 Nissan and INFINITI vehicles listed in the fitment data. It is formed to OE blueprint standards and uses a braided rubber compound selected for durability in high-heat, high-vibration areas. Where required by the original design, protective jackets and heat sleeves are included on the hose assembly to help maintain proper routing and shielding.

This part cross-references Nissan 49717JK000 for the same application. It is a strong match for owners searching for a Nissan 370Z power steering reservoir hose, an INFINITI G37 power steering suction hose, or a replacement hose for INFINITI QX50 reservoir-to-pump routing. The Rein PSH0598 part number is also useful when verifying the correct OE-style replacement before service.

Common Problems This Hose Can Address

• Power steering fluid seepage at the reservoir hose
• Cracking or hardening from heat exposure
• Soft spots or collapse in the suction line
• Noise or poor steering assist caused by air intrusion from a worn hose
• Incorrect fitment from a damaged or previously repaired hose

Installation Notes and Tips

Confirm reservoir-to-pump routing before installation and compare the original hose shape, connection points, and any required shielding. Clean the mating surfaces and inspect nearby clamps, fittings, and fluid condition before reassembly. After installation, refill and bleed the power steering system according to the vehicle service procedure to remove trapped air.
