Detailed Description

Sunsong 5801265 is an engine oil cooler hose assembly made to meet or exceed original equipment performance standards. The hose uses pre-bent tubing to match factory routing, helping maintain proper clearance and alignment in the engine bay. Its steel sections are zinc-coated to resist rust and corrosion from humidity, road salt, water, and grime, while the hose materials are selected for demanding operating conditions. This part cross-references Dorman OE Solutions 625-148 for the same application.

Compatible With select 1997-2000 Chevrolet C2500, C3500, K2500, and K3500 outlet (passenger side) applications, as well as 1997-1999 Chevrolet C1500 Suburban, C2500 Suburban, K1500 Suburban, K2500 Suburban, and Tahoe outlet (passenger side) applications. It also fits 1997-2000 GMC C2500, C3500, K2500, and K3500 outlet (passenger side) applications, plus 1997-1999 GMC C1500 Suburban, C2500 Suburban, K1500 Suburban, K2500 Suburban, and 1997 GMC C1500 and Yukon outlet (passenger side) applications.

What It Helps Fix

• Oil leaks from a cracked or corroded cooler hose
• Restricted oil flow through a damaged hose assembly
• Improper fit from a bent, fatigued, or rusted original line
• Heat-related deterioration in the engine oil cooler circuit
• Corrosion damage from road salt, moisture, and grime

Installation Notes and Tips

Verify the outlet (passenger side) location and confirm the 27mm connecting nut before installation. Compare the original routing, end fittings, and overall length to the replacement part number 5801265 to ensure the correct application for your Chevrolet or GMC truck or SUV. Inspect adjacent cooler lines, seals, and mounting points for wear before reassembly.
