Detailed Product Description and Specifications
This Sunsong power steering pressure line hose assembly (part number 3401690) is engineered to meet the hydraulic requirements of select Dodge trucks. The hose is made from chlorosulfonated polyethylene (CSM), a material known for its resistance to heat, oil, and abrasion, which is critical for maintaining pressure integrity in power steering systems. The assembly measures 29.8 inches (756 mm) in length, providing a precise fit for the specified Dodge models.
Both ends of the hose feature male inverted flare fittings, with the first end sized at 11/16 inch and the second at 5/8 inch. These fittings ensure secure, leak-free connections to the power steering pump and steering gear. The absence of a bracket or power steering switch port simplifies installation and reduces potential failure points.
Applications and Common Issues Addressed
- Replacement for worn or leaking power steering pressure lines on Dodge D100, D150, D200, D300, and Ramcharger
- Resolves power steering fluid leaks that cause steering difficulty or noise
- Prevents pressure loss that can lead to reduced steering responsiveness
- Addresses hose deterioration from heat and chemical exposure
- Eliminates issues related to damaged or corroded fittings
Installation Notes and Technical Tips
When installing the Sunsong 3401690 power steering pressure line hose assembly, ensure all connections are clean and free of debris. The male inverted flare fittings require proper torque to avoid leaks but should not be overtightened to prevent damage. The hose length of 29.8 inches allows for direct replacement without modification on compatible Dodge models. Note that this assembly does not include a bracket or power steering switch port, so existing mounting hardware should be reused if applicable.
