Detailed Description

Sunsong 5801277 is an engine oil cooler hose assembly designed for GM vehicles that use an inlet (lower) hose configuration. It is compatible with 1996-2000 Chevrolet C2500, C3500, K2500, and K3500, plus 1996-1999 Chevrolet C2500 Suburban and K2500 Suburban. The same fitment also covers 1996-2000 GMC C2500, C3500, K2500, and K3500, along with 1996-1999 GMC C2500 Suburban and K2500 Suburban. This part cross-references Dorman OE Solutions 625-178 for the same application.

The hose assembly combines rubber and steel materials to support oil flow while maintaining the correct shape and connection points. Sunsong 5801277 is engineered to restore the original hose path and performance on Chevrolet C2500, GMC K3500, and related GM truck platforms, making it a direct replacement for worn or leaking oil cooler lines.

Common Problems This Part Can Address

  • Oil seepage or leakage at the cooler hose assembly
  • Cracked, hardened, or deteriorated hose material
  • Corrosion or damage in the steel tube section
  • Improper routing or fit from a previous replacement hose
  • Reduced oil cooler line integrity on high-mileage GM trucks

Installation Notes and Tips

Verify the vehicle’s inlet (lower) hose position before ordering. Confirm the end connections match the existing setup: male on one end and quick connect on the other. Inspect adjacent fittings, brackets, and sealing surfaces during replacement so the new hose seats correctly and maintains proper routing.

Quality Assurance

This Sunsong oil cooler hose assembly is manufactured to meet or exceed original equipment performance standards. The tubing is made from high-grade steel with a zinc electroplated finish to improve resistance to rust and corrosion from humidity, road salt, water, and grime.
