Key Features

• Precision-engineered with pre-bent tubing for exact fit
• Includes brackets, grommets, heat shields, bushings, and protective sleeves as required
• High-grade steel tubing with zinc electroplating for corrosion resistance
• Built to meet or exceed original equipment performance standards
• Operating temperature range from -40 to 350 degrees Fahrenheit

Detailed Description

Part number 5801141 is an automatic transmission oil cooler hose assembly designed for 2009-2014 Chevrolet Silverado 1500 and 2007-2014 GMC Sierra 1500 models with HD trans cooling. The pre-bent steel tubing follows the intended routing for the transmission cooler circuit, while the zinc-coated finish helps resist rust and corrosion from humidity, road salt, water, and grime. Part number 5801141 is a practical replacement when the original hose assembly has deteriorated, corroded, or no longer maintains proper fluid transfer.

This part cross-references Dorman - OE Solutions (e.g., 624-145) for the same application.

What It Is Used For

• Replacing a corroded or rusted transmission oil cooler hose assembly
• Restoring proper transmission fluid flow through the cooling circuit
• Addressing leaks caused by worn tubing or degraded hose components
• Correcting fitment issues from damaged brackets, sleeves, or related wear parts
• Maintaining cooling-system routing on HD trans cooling applications

Installation Notes and Tips

Verify the vehicle’s HD trans cooling configuration before ordering. Compare the original routing, mounting points, and connection style to the replacement assembly to confirm application match. Use the existing vehicle-specific attachment points and inspect adjacent cooling components for wear before installation.

Quality Assurance

Sunsong manufactures this hose assembly from high-grade steel with zinc electroplating to improve resistance to corrosion and rust. The assembly is engineered to meet or exceed original equipment performance standards and is rated for a wide operating temperature range.
