Detailed Description

The Sunsong 5801270 is an OE-style engine oil cooler hose assembly engineered for vehicles that use a lower outlet configuration. It is built with pre-bent steel tubing and rubber hose sections to match factory routing, helping maintain proper clearance and fit in the engine bay. The steel sections are zinc-coated to resist rust and corrosion from moisture, road salt, and grime.

This part cross-references Dorman OE Solutions 625-163 for the same application. It is a direct-fit replacement for select 1991-1993 Chevrolet K1500, K2500, and K3500 models, along with 1992-1993 Chevrolet Blazer and K1500/K2500 Suburban, and 1992-1993 GMC Yukon applications. The Sunsong 5801270 is also listed for select GMC K1500, K2500, and K3500 trucks with the specified axle ratio and cooling package notes.

What It Helps Fix

• Oil cooler hose leaks caused by age, heat, or cracking
• Corrosion in steel cooler lines and fittings
• Improper routing from damaged or bent original hoses
• Restricted oil flow through worn cooler hose assemblies
• Fitment issues on lower outlet oil cooler line replacements

Installation Notes

Verify the vehicle’s year, make, model, and lower outlet configuration before ordering. Fitment includes application-specific notes such as axle ratio and auxiliary cooler requirements, so match the vehicle build details carefully. The hose uses a male end fitting on one side and a quick connect on the other, which helps support OE-style connection points during replacement.

For best results, compare the original hose routing and connection style before installation. Confirm that the replacement line follows the factory path and clears nearby components without stress or twisting.

Quality Assurance

Sunsong manufactures this oil cooler hose assembly to meet or exceed original equipment performance standards. The combination of pre-bent tubing, corrosion-resistant steel, and temperature-capable hose materials supports reliable service in harsh underhood conditions.
