• Pre-bent tubing for exact fit and OE-style routing
• Rubber and steel hose construction
• Operating temperature range of -40 to 350 degrees Fahrenheit
• High-grade steel tubing with zinc electroplating for corrosion resistance
• Designed for upper outlet oil cooler applications
• Cross-references Dorman OE Solutions 625-134 for the same application

Detailed Description

This Sunsong oil cooler hose assembly is designed for Chevrolet and GMC C/K trucks that use an upper outlet configuration. The pre-formed tubing helps maintain the original hose path, while the steel sections are zinc-coated to resist rust and corrosion from humidity, road salt, water, and grime. Sunsong 5801255 is a practical replacement for worn, leaking, or damaged oil cooler hose assemblies on 1988-1994 Chevrolet C1500, C2500, C3500, K1500, K2500, K3500 and GMC C1500, C2500, C3500, K1500, K2500, K3500 models with the listed cooling configurations.

Part number 5801255 is built to restore oil flow between the engine and cooler while matching the original fitment requirements for these GM truck applications. It is also referenced by 12472265 and B64252.

What This Part Helps Fix

• Oil seepage or leakage from a damaged cooler hose
• Cracked, hardened, or heat-damaged hose material
• Corrosion on the original steel line sections
• Poor routing or fitment after previous repairs
• Reduced oil cooling performance from a restricted or failing hose assembly

Installation Notes and Tips

• Verify upper outlet routing before installation.
• Confirm vehicle year, make, model, and cooling configuration against the fitment list.
• Inspect mating connections and surrounding components for wear before installing the new assembly.
• Check clearance around the pre-bent tubing to ensure proper alignment with factory mounting points.

Quality Assurance

Sunsong 5801255 is manufactured to meet or exceed original equipment performance standards. The steel tubing uses a zinc coating for added resistance to corrosion and rust, and the assembly is engineered for the temperature range required in demanding engine oil cooling service.
