Sunsong 5801154 Automatic Transmission Oil Cooler Hose Assembly - Transmission to Radiator (Upper)

Automatic Transmission Oil Cooler Hose for GM Trucks

Sunsong 5801154 is an automatic transmission oil cooler hose assembly built for upper transmission-to-radiator routing on select Chevrolet Silverado, GMC Sierra, and related GM full-size trucks. It uses quick connect ends and a steel-and-rubber construction to restore the transmission cooler line path with an OE-style fit.

Key Features

• Quick connect fittings on both ends for direct connection at the transmission and radiator
• Steel and rubber hose construction for the upper transmission cooler line route
• 20 in. length for the specified GM applications
• Operating temperature range from -40 to 350 degrees Fahrenheit
• Precision-formed tubing with corrosion-resistant zinc plating
• Built to meet or exceed original equipment performance standards

Detailed Product Overview

This Sunsong automatic transmission oil cooler hose assembly is engineered for the transmission to radiator (upper) position on applications such as the Chevrolet Silverado 1500, Silverado 2500 HD, Silverado 3500, GMC Sierra 2500 HD, Sierra 3500, and Yukon XL 2500. Part number 5801154 is designed to match the original routing and connection style used on these trucks, helping maintain proper transmission fluid flow through the cooler circuit. The steel tubing is zinc electroplated for added resistance to rust and corrosion from road salt, moisture, and grime.

This part cross-references Dorman OE Solutions 624-488 for the same application.

What This Hose Assembly Helps Address

• Transmission cooler line leaks at the upper radiator connection
• Corrosion or rust on the original cooler hose assembly
• Cracked, weakened, or damaged rubber sections in the cooler line
• Improper routing or fit after replacement of worn transmission lines
• Restricted transmission fluid transfer caused by deteriorated hose components

Installation Notes and Tips

Verify the vehicle’s transmission-to-radiator upper line routing before installation. Confirm quick connect end style, hose length, and application match for your Silverado, Sierra, or Suburban platform. Inspect surrounding brackets, grommets, heat shields, bushings, and sleeves during service and replace any worn related components as needed to restore the line path to original condition.
