Sunsong 5801004 Engine Oil Cooler Hose Assembly - Inlet (Lower)

Engine Oil Cooler Hose Assembly for GM Trucks

Sunsong 5801004 is an engine oil cooler hose assembly built for select Chevrolet and GMC trucks and SUVs from 1985-1991. It is engineered for the lower inlet position and uses a rubber-and-steel construction to match OE-style routing and durability.

With pre-bent tubing and corrosion-resistant steel, this hose assembly is made to restore the original oil cooler line path on applications such as Chevrolet Blazer, GMC Jimmy, and Chevrolet/GMC Suburban and V-series models. The Sunsong 5801004 also meets or exceeds original equipment performance standards and is rated for temperatures from -40 to 350 degrees Fahrenheit.

Detailed Description

This Sunsong oil cooler hose assembly is designed for direct replacement on 1985-1991 Chevrolet Blazer, 1985-1991 GMC Jimmy, and related Chevrolet and GMC K-series and V-series applications. The hose uses a combination of rubber and steel to support proper oil flow while maintaining the formed shape needed for factory-style fitment. Sunsong 5801004 is a practical choice when replacing a worn, leaking, or corroded lower inlet oil cooler line on these GM platforms.

This part cross-references Dorman OE Solutions 625-131 for the same application.

What It Helps Fix

• Oil leaks from a cracked or deteriorated cooler hose
• Corrosion on the original steel line
• Restricted oil flow caused by damaged tubing
• Improper routing after a previous repair
• Heat-related hose breakdown in the engine bay

Installation Notes and Tips

Verify the lower inlet position and compare the original line routing before installation. Check all connection points, brackets, and surrounding components for wear or damage so the replacement line seats correctly and maintains proper clearance from heat sources and moving parts.

Quality Assurance

Sunsong manufactures this hose assembly with high-grade steel, zinc plating, and OE-level temperature resistance to support long-term service in demanding underhood conditions. The design follows original equipment performance expectations for the listed Chevrolet and GMC applications.
