Sunsong 3402463 Power Steering Return Line Hose Assembly - Cooler To Reservoir

Power Steering Return Hose for Chrysler Pacifica

The Sunsong 3402463 power steering return line hose assembly is built for low-pressure, high-temperature return-side service and is engineered for direct replacement on select Chrysler Pacifica applications. It is a fitment-specific solution for restoring proper fluid routing on 2004-2006 Chrysler Pacifica models at the cooler-to-reservoir position.

Key Features

• Direct-fit power steering return line hose assembly for the cooler to reservoir route
• 3/8 in. ID hose connections at both ends
• 56.5 in. overall length for application-specific routing
• CSM hose material for return-line service
• Rated for a maximum working pressure of 250 psi
• Steel tubing with zinc electroplating for corrosion and rust resistance
• Precision-engineered to restore original hose routing and wearable components as required by the application

Detailed Description

Sunsong 3402463 is a power steering return line hose assembly made for 2004-2006 Chrysler Pacifica vehicles in the cooler to reservoir position. This hose assembly uses 3/8 in. ID hose fittings on both ends and measures 56.5 in. in length, helping maintain the correct routing and connection points for the steering system. The steel tubing is zinc-coated to resist corrosion from humidity, road salt, water, and grime, making it a practical replacement for aging or damaged return lines. This part cross-references Dorman - HELP 80425 and Gates 363740 for the same application.

What This Part Helps Address

• Power steering fluid seepage from a worn return hose
• Cracked, hardened, or deteriorated hose material
• Corrosion on the original steel line section
• Incorrect routing or fitment after prior repairs
• Noise or steering performance issues caused by restricted fluid return

Installation Notes and Tips

Verify the cooler-to-reservoir routing before installation and compare the original hose length, end sizes, and connection style to the replacement part. On 2004-2006 Chrysler Pacifica models, confirm that the vehicle uses the listed return-line configuration and inspect nearby brackets, grommets, heat shields, bushings, and sleeves for wear before reassembly. Clean the connection points and check for leaks after filling and bleeding the power steering system.

Quality Assurance

Sunsong states that its return hoses exceed original equipment performance standards for low-pressure, high-temperature operation. The assembly is manufactured with corrosion-resistant steel tubing and application-specific engineering to support a proper OE-style replacement on the Chrysler Pacifica.
