Detailed Description

Sunsong 5801269 is an engine oil cooler hose assembly made for vehicles that use a pre-formed upper inlet hose layout. The assembly uses pre-bent steel tubing with a rubber section to match the original routing and maintain proper clearance around surrounding components. High-grade steel tubing with zinc electroplating adds corrosion resistance against humidity, road salt, water, and grime, which is important for older Chevrolet and GMC truck platforms that see demanding road conditions.

This hose assembly is listed for 1991-1993 Chevrolet K1500, K2500, and K3500, 1992-1993 Chevrolet Blazer, K1500 Suburban, and K2500 Suburban, and 1992-1993 GMC Yukon. It also covers 1991-1993 GMC K1500, K2500, and K3500 applications with the specified axle ratio and without the HD auxiliary cooler where noted. If you are replacing a leaking or damaged upper oil cooler line on a Chevrolet K1500 or GMC K2500, this part number 5801269 provides a direct replacement path.

This part cross-references Dorman OE Solutions 625-162 for the same application.

What It Helps Fix

• Oil seepage or leakage from a worn cooler hose
• Cracked, hardened, or heat-damaged hose material
• Corrosion on the steel line section
• Restricted oil flow caused by a damaged hose assembly
• Fitment issues from an incorrect upper inlet replacement line

Installation Notes and Tips

Verify the vehicle’s axle ratio, cooling equipment, and oil cooler routing before ordering. This assembly is for the inlet (upper) position only and is listed with a male fitting on one end and a quick connect on the other. Compare the original hose shape, length, and connection style to confirm a proper match for your Chevrolet Blazer, GMC Yukon, or other listed GM truck application.

Quality Assurance

Sunsong states that this oil cooler hose assembly is manufactured to meet or exceed original equipment performance standards. The steel tubing is zinc electroplated for added resistance to rust and corrosion, and the hose is rated for a wide operating temperature range from -40 to 350 degrees Fahrenheit.
