Detailed Description

This Sunsong power steering pressure line hose assembly is built to restore hydraulic steering performance on vehicles using a Chrysler power steering pump without an air pump. The hose is manufactured to exact fit standards and is designed around the original routing and connection points for the listed Chrysler New Yorker, Newport, Town & Country, Imperial, and Dodge Monaco applications. Sunsong 3403037 also cross-references Gates 364360 for the same application.

According to the manufacturer, the hose assembly is constructed to handle up to 1,500 psi working pressure, with an 8,700 psi burst rating and 1,600 lb tensile strength. The steel tubing uses a zinc coating to help resist rust and corrosion from humidity, road salt, water, and grime, making it a practical replacement for aging factory steering lines. Part number 3403037 is a direct-fit service part for the specified Chrysler and Dodge vehicles.

What It Helps Address

• Power steering fluid leaks from a worn pressure line
• Hard or inconsistent steering assist caused by hose deterioration
• Cracked, rusted, or corroded steering line tubing
• Noise or pressure loss in the hydraulic steering circuit
• Service replacement for an original hose that no longer seals properly

Installation Notes and Tips

Verify the vehicle uses a Chrysler PS pump and does not have an air pump before ordering. Confirm the 5/16 in. and 3/8 in. male O-ring connections match the original hose, and compare the 35 in. overall length to the removed part. Clean the mating surfaces and inspect related steering components for wear before installation to help ensure proper sealing and operation.

Quality Assurance

Each hose is subjected to a high-pressure quality assurance test before it leaves the factory. Sunsong builds this pressure line hose to exceed original equipment performance standards for pressure, burst strength, and corrosion resistance.
