Detailed Description

This Dorman transmission line is built to move automatic transmission fluid between the transmission and the cooler while maintaining a secure connection at both ends. The hose assembly uses rubber hose material with metal and rubber components in the overall construction, helping maintain leak-free fluid delivery in demanding underhood conditions. Dorman 624-139 is a practical replacement for worn, damaged, or leaking cooler hose assemblies on the Chevrolet Cavalier and Pontiac Sunfire.

This part cross-references Sunsong 5801170 and OE number 22597967 for the same application.

What It Helps Fix

• Transmission fluid leaks at the cooler line connection
• Cracked or deteriorated cooler hose material
• Restricted fluid transfer between the transmission and cooler
• Damaged male-thread hose ends
• Heat-related hose failure in the transmission cooling circuit

Installation Notes and Tips

Verify outlet (lower) fitment before installation on 1995-2001 Chevrolet Cavalier and 1995-2001 Pontiac Sunfire models. Inspect the mating threads, sealing surfaces, and adjacent cooler lines for wear or contamination before connecting the new hose assembly. Confirm routing matches the original line path to avoid contact with hot or moving components.
