It is a direct replacement style hose assembly for select GM trucks and SUVs, including Chevrolet Silverado and GMC Sierra applications, with fitment that varies by model and cooling package.

• Transfers heat away from transmission fluid to support stable fluid temperatures.
• Manufactured and leakage-tested to meet strict quality standards.
• Fits upper, inlet, and transmission-to-radiator upper applications, depending on vehicle.
• Compatible with select Chevrolet Silverado 1500, GMC Sierra 1500, and Cadillac Escalade applications.

What It Helps Address

• Transmission fluid overheating.
• Cracked, leaking, or deteriorated cooler hoses.
• Restricted fluid flow in the cooling circuit.
• Loss of cooling performance from a worn hose assembly.

Installation Notes and Tips

Verify the vehicle’s cooling configuration before ordering, since fitment depends on auxiliary cooler equipment and, on some applications, RPO code KNP. Match the hose routing and connection points to the original part before installation. This part cross-references Dorman - OE Solutions 624-153 for the same application.
